Class CIM_MessageLog

extends CIM_Log
MessageLog represents any type of event, error or informational register or chronicle. The object describes the existence of the log and its characteristics. Several methods are defined for retrieving, writing and deleting log entries, and maintaining the log. This type of log uses iterators to access the log records, whereas its peer class, RecordLog, uses more abstracted access mechanisms.

		Description	string	CommunicationStatus indicates the ability of the instrumentation to communicate with the underlying ManagedElement. CommunicationStatus consists of one of the following values: Unknown, None, Communication OK, Lost Communication, or No Contact. A Null return indicates the implementation (provider) does not implement this property. "Unknown" indicates the implementation is in general capable of returning this property, but is unable to do so at this time. "Not Available" indicates that the implementation (provider) is capable of returning a value for this property, but not ever for this particular piece of hardware/software or the property is intentionally not used because it adds no meaningful information (as in the case of a property that is intended to add additional info to another property). "Communication OK " indicates communication is established with the element, but does not convey any quality of service. "No Contact" indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.

DetailedStatus	uint16
		Description	string	DetailedStatus compliments PrimaryStatus with additional status detail. It consists of one of the following values: Not Available, No Additional Information, Stressed, Predictive Failure, Error, Non-Recoverable Error, SupportingEntityInError. Detailed status is used to expand upon the PrimaryStatus of the element. A Null return indicates the implementation (provider) does not implement this property. "Not Available" indicates that the implementation (provider) is capable of returning a value for this property, but not ever for this particular piece of hardware/software or the property is intentionally not used because it adds no meaningful information (as in the case of a property that is intended to add additional info to another property). "No Additional Information" indicates that the element is functioning normally as indicated by PrimaryStatus = "OK". "Stressed" indicates that the element is functioning, but needs attention. Examples of "Stressed" states are overload, overheated, and so on. "Predictive Failure" indicates that an element is functioning normally but a failure is predicted in the near future. "Non-Recoverable Error " indicates that this element is in an error condition that requires human intervention. "Supporting Entity in Error" indicates that this element might be "OK" but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower-layer networking problems.	None	TRANSLATABLE= true

ElementName	string
ElementName	string	Description	string	A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.	None	TRANSLATABLE= true
EnabledDefault	uint16
		Description	string	An enumerated value indicating an administrator's default or startup configuration for the Enabled State of an element. By default, the element is "Enabled" (value=2).	None	TRANSLATABLE= true

		Write	boolean	true	None	None
EnabledState	uint16
		Description	string	EnabledState is an integer enumeration that indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value=4) and starting (value=10) are transient states between enabled and disabled. The following text briefly summarizes the various enabled and disabled states: Enabled (2) indicates that the element is or could be executing commands, will process any queued commands, and queues new requests. Disabled (3) indicates that the element will not execute commands and will drop any new requests. Shutting Down (4) indicates that the element is in the process of going to a Disabled state. Not Applicable (5) indicates the element does not support being enabled or disabled. Enabled but Offline (6) indicates that the element might be completing commands, and will drop any new requests. Test (7) indicates that the element is in a test state. Deferred (8) indicates that the element might be completing commands, but will queue any new requests. Quiesce (9) indicates that the element is enabled but in a restricted mode. Starting (10) indicates that the element is in the process of going to an Enabled state. New requests are queued.

HeaderFormat	string
HeaderFormat	string	Description	string	If the SizeOfHeader property is non-zero, this property describes the structure and format of the Log header. It is a free-form string. If the SizeOfHeader property is 0, then the information in this property is undefined.	None	TRANSLATABLE= true
HealthState	uint16
		Description	string	Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely non-functional. The following continuum is defined: "Non-recoverable Error" (30) - The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost. "Critical Failure" (25) - The element is non-functional and recovery might not be possible. "Major Failure" (20) - The element is failing. It is possible that some or all of the functionality of this component is degraded or not working. "Minor Failure" (15) - All functionality is available but some might be degraded. "Degraded/Warning" (10) - The element is in working order and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors. "OK" (5) - The element is fully functional and is operating within normal operational parameters and without error. "Unknown" (0) - The implementation cannot report on HealthState at this time. DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.	None	TRANSLATABLE= true
		ValueMap	string	0, 5, 10, 15, 20, 25, 30, ..	None	None
		Values	string	Unknown, OK, Degraded/Warning, Minor failure, Major failure, Critical failure, Non-recoverable error, DMTF Reserved	None	TRANSLATABLE= true
InstallDate	datetime
		Description	string	A datetime value that indicates when the object was installed. Lack of a value does not indicate that the object is not installed.	None	TRANSLATABLE= true
		MappingStrings	string	MIF.DMTF\|ComponentID\|001.5	None	None
InstanceID	string
InstanceID	string	Description	string	InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: <OrgID>:<LocalID> Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>. <LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. If not set to null for DMTF-defined instances, the "preferred" algorithm must be used with the <OrgID> set to CIM.	None	TRANSLATABLE= true
IsFrozen	boolean
IsFrozen	boolean	Description	string	Boolean indicating that the Log is currently frozen and modifications are not allowed.	None	TRANSLATABLE= true

		Values	string	Unknown, Add, Delete, Modify, Log Cleared	None	TRANSLATABLE= true
LogState	uint16
		Description	string	LogState is an integer enumeration that indicates the current state of a log represented by CIM_Log subclasses. LogState is to be used in conjunction with the EnabledState property to fully describe the current state of the log. The following text briefly summarizes the various log states: Unknown (0) indicates the state of the log is unknown. Normal (2) indicates that the log is or could be executing logging commands, will process any queued log entries, and will queue new logging requests. Erasing (3) indicates that the log is being erased. Not Applicable (4) indicates the log does not support representing a log state.	None	TRANSLATABLE= true
		ModelCorrespondence	string	CIM_EnabledLogicalElement.EnabledState	None	None

MaxLogSize	uint64
		Description	string	The maximum size, in bytes, to which the Log can grow. If there is no maximum, then MaxLogSize should be set to 0.	None	TRANSLATABLE= true
		Units	string	Bytes	None	TRANSLATABLE= true
MaxNumberOfRecords	uint64
MaxNumberOfRecords	uint64	Description	string	Maximum number of records that can be captured in the Log. If undefined, a value of zero should be specified.	None	TRANSLATABLE= true
MaxRecordSize	uint64
		Description	string	Maximum size, in bytes, to which an individual Log entry (record) can grow - if the Capabilities array includes a value of 7 ("Variable Length Records Supported"). If the Capabilities array does not include a 7, then the Log only supports fixed length entries. The size of these entries is described by this property.	None	TRANSLATABLE= true
		Units	string	Bytes	None	TRANSLATABLE= true

		Override	string	Name	TOSUBCLASS= false	None
OperatingStatus	uint16
		Description	string	OperatingStatus provides a current status value for the operational condition of the element and can be used for providing more detail with respect to the value of EnabledState. It can also provide the transitional states when an element is transitioning from one state to another, such as when an element is transitioning between EnabledState and RequestedState, as well as other transitional conditions. OperatingStatus consists of one of the following values: Unknown, Not Available, In Service, Starting, Stopping, Stopped, Aborted, Dormant, Completed, Migrating, Emmigrating, Immigrating, Snapshotting. Shutting Down, In Test A Null return indicates the implementation (provider) does not implement this property. "Unknown" indicates the implementation is in general capable of returning this property, but is unable to do so at this time. "None" indicates that the implementation (provider) is capable of returning a value for this property, but not ever for this particular piece of hardware/software or the property is intentionally not used because it adds no meaningful information (as in the case of a property that is intended to add additional info to another property). "Servicing" describes an element being configured, maintained, cleaned, or otherwise administered. "Starting" describes an element being initialized. "Stopping" describes an element being brought to an orderly stop. "Stopped" and "Aborted" are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the state and configuration of the element might need to be updated. "Dormant" indicates that the element is inactive or quiesced. "Completed" indicates that the element has completed its operation. This value should be combined with either OK, Error, or Degraded in the PrimaryStatus so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error). "Migrating" element is being moved between host elements. "Immigrating" element is being moved to new host element. "Emigrating" element is being moved away from host element. "Shutting Down" describes an element being brought to an abrupt stop. "In Test" element is performing test functions. "Transitioning" describes an element that is between states, that is, it is not fully available in either its previous state or its next state. This value should be used if other values indicating a transition to a specific state are not applicable. "In Service" describes an element that is in service and operational.	None	TRANSLATABLE= true

		ValueMap	string	0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, .., 0x8000..	None	None

OperationalStatus	uint16
		ArrayType	string	Indexed	None	OVERRIDABLE= false
		Description	string	Indicates the current statuses of the element. Various operational statuses are defined. Many of the enumeration's values are self-explanatory. However, a few are not and are described here in more detail. "Stressed" indicates that the element is functioning, but needs attention. Examples of "Stressed" states are overload, overheated, and so on. "Predictive Failure" indicates that an element is functioning nominally but predicting a failure in the near future. "In Service" describes an element being configured, maintained, cleaned, or otherwise administered. "No Contact" indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it. "Lost Communication" indicates that the ManagedSystem Element is known to exist and has been contacted successfully in the past, but is currently unreachable. "Stopped" and "Aborted" are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the state and configuration of the element might need to be updated. "Dormant" indicates that the element is inactive or quiesced. "Supporting Entity in Error" indicates that this element might be "OK" but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower-layer networking problems. "Completed" indicates that the element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error). "Power Mode" indicates that the element has additional power model information contained in the Associated PowerManagementService association. OperationalStatus replaces the Status property on ManagedSystemElement to provide a consistent approach to enumerations, to address implementation needs for an array property, and to provide a migration path from today's environment to the future. This change was not made earlier because it required the deprecated qualifier. Due to the widespread use of the existing Status property in management applications, it is strongly recommended that providers or instrumentation provide both the Status and OperationalStatus properties. Further, the first value of OperationalStatus should contain the primary status for the element. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.	None	TRANSLATABLE= true

OtherEnabledState	string
		Description	string	A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1.	None	TRANSLATABLE= true
		ModelCorrespondence	string	CIM_EnabledLogicalElement.EnabledState	None	None

		ModelCorrespondence	string	CIM_MessageLog.OverwritePolicy	None	None
OverwritePolicy	uint16
		Description	string	An enumeration describing the behavior of the Log, when it becomes full or near full. For example, the Log may wrap (value=2) or may simply stop recording entries (value =7). Some of the property's possible values need further explanation: 3="Clear When Near Full" indicates that all of the Log's entries will be deleted when a specified record capacity is reached. The capacity is specified in percentage, using the property, PercentageNearFull. 'Near Full' may be less than 100% if the Log takes time to clear, and a position should always be available for new records. 4="Overwrite Outdated When Needed" describes that Log entries (timestamped later than the date/time specified in the property, TimeWhenOutdated) can be overwritten. 5="Remove Outdated Records" specifies that records (timestamped later than the date/time specified in the property, TimeWhenOutdated) are logically and/or physically removed from the Log. 6="Overwrite Specific Records" indicates that specially flagged records may be overwritten. This property only makes sense when the Capabilities array includes a value of 10, "Can Flag Records for Overwrite".	None	TRANSLATABLE= true

		Units	string	Percent	None	TRANSLATABLE= true
PrimaryStatus	uint16
		Description	string	PrimaryStatus provides a high level status value, intended to align with Red-Yellow-Green type representation of status. It should be used in conjunction with DetailedStatus to provide high level and detailed health status of the ManagedElement and its subcomponents. PrimaryStatus consists of one of the following values: Unknown, OK, Degraded or Error. "Unknown" indicates the implementation is in general capable of returning this property, but is unable to do so at this time. "OK" indicates the ManagedElement is functioning normally. "Degraded" indicates the ManagedElement is functioning below normal. "Error" indicates the ManagedElement is in an Error condition.	None	TRANSLATABLE= true

RecordHeaderFormat	string
RecordHeaderFormat	string	Description	string	If the SizeOfRecordHeader property is non-zero, this property describes the structure and format of the record headers. It is a free-form string. If the SizeOfRecordHeader property is 0, then the information in this property is undefined.	None	TRANSLATABLE= true
RecordLastChanged	uint64
RecordLastChanged	uint64	Description	string	When a change is made to the Log, the record number that was modified is captured.	None	TRANSLATABLE= true
RequestedState	uint16
		Description	string	RequestedState is an integer enumeration that indicates the last requested or desired state for the element, irrespective of the mechanism through which it was requested. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. Note that when EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. "Unknown" (0) indicates the last requested state for the element is unknown. Note that the value "No Change" (5) has been deprecated in lieu of indicating the last requested state is "Unknown" (0). If the last requested or desired state is unknown, RequestedState should have the value "Unknown" (0), but may have the value "No Change" (5).Offline (6) indicates that the element has been requested to transition to the Enabled but Offline EnabledState. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the element is first "Disabled" and then "Enabled". The distinction between requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as Start or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. If knowledge of the last RequestedState is not supported for the EnabledLogicalElement, the property shall be NULL or have the value 12 "Not Applicable".	None	TRANSLATABLE= true

SizeOfHeader	uint64
		Description	string	The size of the Log header, in bytes, if one is present. If there is no Log header, then this property should be set to 0. Headers may include general information about the Log such as the current number of records, time of last update, or a pointer to the location of the first Log entry. Note that this property is NOT the size of the header for an individual Log entry. The latter is described by the property, SizeOfRecordHeader.	None	TRANSLATABLE= true
		Units	string	Bytes	None	TRANSLATABLE= true
SizeOfRecordHeader	uint64
		Description	string	The size of the header for the Log's individual entries, in bytes, if record headers are defined. If there are no record headers, then this property should be set to 0. Record headers may include information such as the type of the Log entry, the date/time that the entry was last updated, or a pointer to the start of optional data. Note that this property defines the header size for individual records in the Log, while the SizeOfHeader property describes the Log's overall header, typically located at the start of the MessageLog.	None	TRANSLATABLE= true
		Units	string	Bytes	None	TRANSLATABLE= true
Status	string
		Deprecated	string	CIM_ManagedSystemElement.OperationalStatus	TOSUBCLASS= false	None
		Description	string	A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for 3 reasons: 1) Status is more correctly defined as an array. This definition overcomes the limitation of describing status using a single value, when it is really a multi-valued property (for example, an element might be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus.	None	TRANSLATABLE= true

Name	Return Type	Qualifiers
Name	Return Type	Name	Data Type	Value	Scope	Flavors
CancelIteration()	uint32
CancelIteration()	uint32	Description	string	Requests that an iteration of the Log, identified by the IterationIdentifier input parameter, be stopped. The return value from CancelIteration should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
DeleteRecord()	uint32
DeleteRecord()	uint32	Description	string	Requests that the record indicated by the IterationIdentifier be deleted from the MessageLog. After deletion, the Iteration Identifier may be advanced to the next record by setting the PositionToNext input parameter to TRUE. If set to FALSE, then the IterationIdentifier will be positioned at the previous record. Two output parameters are defined for the method - RecordData which holds the contents of the deleted Log entry (as an array of bytes that can be recast to an appropriate format or discarded), and RecordNumber which returns the current record number addressed via the IterationIdentifier. The RecordNumber parameter is only defined/valid when the Capabilities array indicates that ordinal record number addressing is supported (a value of 7). IterationIdentifier is defined as an Input/Output method parameter to allow the Log to embed state information in the Identifier and potentially let the identifier be maintained by the using application. The return value from DeleteRecord should be 0 if the request was successfully executed, 1 if the request is not supported, and some other value if an error occurred. If the request is not supported, check the Capabilities array that a value of 3 ("Delete Record Supported") is specified. Note: In a subclass, the set of possible return codes could be described using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
FlagRecordForOverwrite()	uint32
FlagRecordForOverwrite()	uint32	Description	string	Requests that the record indicated by the IterationIdentifier be flagged as overwriteable. This method is only supported when the Capabilities array includes a value of 10, "Can Flag Records for Overwrite". After updating the entry, the IterationIdentifier may be advanced to the next record by setting the PositionToNext input parameter to TRUE. One output parameter is defined for the method RecordNumber. It returns the current record number addressed via the Iteration Identifier. This parameter is only defined/valid when the Capabilities array indicates that ordinal record number addressing is supported (a value of 7). IterationIdentifier is defined as an Input/Output method parameter to allow the Log to embed state information in the Identifier and potentially let the identifier be maintained by the using application. The return value from FlagRecordForOverwrite should be 0 if the request was successfully executed, 1 if the request is not supported, and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
FreezeLog()	uint32
FreezeLog()	uint32	Description	string	Requests that the MessageLog be placed in a frozen state ("Freeze" input parameter = TRUE) or 'unfrozen' (= FALSE). If frozen, modifications to the Log will not be allowed. If successful, the Log's IsFrozen boolean property will be updated to reflect the desired state. The method's return code should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. If the request is not supported, check the Capabilities array that a value of 5 ("Freeze Log Supported") is specified. Note: In a subclass, the set of possible return codes could be described using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
GetRecord()	uint32
GetRecord()	uint32	Description	string	Requests that the record indicated by the IterationIdentifier be retrieved from the MessageLog. After retrieval, the IterationIdentifier may be advanced to the next record by setting the PositionToNext input parameter to TRUE. Two output parameters are defined for the method - RecordData which holds the contents of the Log entry (as an array of bytes that can be recast to an appropriate format), and RecordNumber which returns the current record number addressed via the Iteration Identifier. The RecordNumber parameter is only defined/valid when the Capabilities array indicates that ordinal record number addressing is supported (a value of 7). IterationIdentifier is defined as an Input/Output method parameter to allow the Log to embed state information in the Identifier and potentially let the identifier be maintained by the using application. The return value from GetRecord should be 0 if the request was successfully executed, 1 if the request is not supported, and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
PositionAtRecord()	uint32
PositionAtRecord()	uint32	Description	string	Requests that the Log's iteration identifier be advanced or retreated a specific number of records, or set to the entry at a specified numeric location. These two different behaviors are accomplished using the input parameters of the method. Advancing or retreating is achieved by setting the MoveAbsolute boolean to FALSE, and then specifying the number of entries to advance or retreat as positive or negative values in the RecordNumber parameter. Moving to a specific record number is accomplished by setting the MoveAbsolute input parameter to TRUE, and then placing the record number into the RecordNumber parameter. This can only be done if the Capabilities array includes a value of 7, "Supports Addressing by Ordinal Record Number". After the method completes and if ordinal record numbers are supported (the Capabilities array includes a 7), the current record number is returned in the RecordNumber output parameter. Otherwise, the value of the parameter is undefined. IterationIdentifier is defined as an Input/Output method parameter to allow the Log to embed state information in the Identifier and potentially let the identifier be maintained by the using application. The return value from PositionAtRecord should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. If the request is not supported, check the Capabilities array regarding support for ordinal record number addressing and backward movement in the Log (values 7 and 4, respectively). Note: In a subclass, the set of possible return codes could be described using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
PositionToFirstRecord()	uint32
PositionToFirstRecord()	uint32	Description	string	Requests that an iteration of the MessageLog be established and that the iterator be set to the first entry in the Log. An identifier for the iterator is returned as an output parameter of the method. Regarding iteration, you have 2 choices: 1) Embed iteration data in the method call, and allow implementations to track/ store this data manually; or, 2) Iterate using a separate object (for example, class ActiveIterator) as an iteration agent. The first approach is used here for interoperability. The second requires an instance of the Iterator object for EACH iteration in progress. 2's functionality could be implemented underneath 1. The return value from PositionToFirstRecord should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
WriteRecord()	uint32
WriteRecord()	uint32	Description	string	Requests that a record be inserted at the Log position indicated by the IterationIdentifier. The entry's data is provided in the RecordData input parameter. After insertion, the IterationIdentifier may be advanced to the next record by setting the PositionToNext input parameter to TRUE. The output parameter, RecordNumber, returns the current record number addressed via the IterationIdentifier. This parameter is only defined/valid when the Capabilities array indicates that ordinal record number addressing is supported (a value of 7). IterationIdentifier is defined as an Input/Output method parameter to allow the Log to embed state information in the Identifier and potentially let the identifier be maintained by the using application. The return value from WriteRecord should be 0 if the request was successfully executed, 1 if the request is not supported, and some other value if an error occurred. If the request is not supported, check the Capabilities array that a value of 2 ("Write Record Supported") is specified. Note: In a subclass, the set of possible return codes could be described using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.	None	TRANSLATABLE= true
