Detailed Description

This class manages subregions and cached data.

Each region can contain multiple subregions and entries for data. Regions provide a hierachical name space within the cache. Also, a region can be used to group cached objects for management purposes.

Entries managed by the region are key-value pairs. A set of region attributes is associated with the region when it is created.

The Region interface basically contains two set of APIs: Region management APIs and (potentially) distributed operations on entries. Non-distributed operations on entries are provided by RegionEntry.

Each Cache defines regions called the root regions. User applications can use the root regions to create subregions for isolated name space and object grouping.

A region's name can be any String, except that it should not contain the region name separator, a forward slash (/).

Regions can be referenced by a relative path name from any region higher in the hierarchy in Region::getSubregion. You can get the relative path from the root region with Region::getFullPath. The name separator is used to concatenate all the region names together from the root, starting with the root's subregions.

virtual void apache::geode::client::Region::clear ( const UserDataPtr & aCallbackArgument = ::apache::geode::client::NullSharedBase::s_instancePtr )

pure virtual

Removes all entries from this region and provides a user-defined parameter object to any CacheWriter or CacheListener invoked in the process.

See also: CacheListener::afterRegionClear; CacheWriter::beforeRegionClear

virtual bool apache::geode::client::Region::containsKey ( const CacheableKeyPtr & keyPtr ) const

pure virtual

Only the client's cache is searched for the key.

It does not go to the java server to which it is connected with.

template<class KEYTYPE >

bool apache::geode::client::Region::containsKey ( const KEYTYPE & key ) const

inline

Convenience method allowing key to be a const char* This operations checks for the key in the local cache .

It is not propagated to the Geode cache server to which it is connected.

virtual bool apache::geode::client::Region::containsKeyOnServer ( const CacheableKeyPtr & keyPtr ) const

pure virtual

The cache of the server, to which it is connected with, is searched for the key to see if the key is present.

Exceptions

UnsupportedOperationException if the region's scope is ScopeType::LOCAL.

virtual bool apache::geode::client::Region::containsValueForKey ( const CacheableKeyPtr & keyPtr ) const

pure virtual

This operations checks for the value in the local cache .

It is not propagated to the Geode cache server to which it is connected.

Convenience method allowing key to be a const char* This operations checks for the value in the local cache .

It is not propagated to the Geode cache server to which it is connected.

virtual void apache::geode::client::Region::create	(	const CacheableKeyPtr &	key,
		const CacheablePtr &	value,
		const UserDataPtr &	aCallbackArgument = `::apache::geode::client::NullSharedBase::s_instancePtr`
	)

pure virtual

Creates a new entry in this region with the specified key and value, providing a user-defined parameter object to any CacheWriter invoked in the process.

The same parameter is also passed to the CacheListener, if one is defined for this Region, invoked in the process. The new entry is propogated to the java server also to which it is connected with.

Updates the CacheStatistics::getLastAccessedTime and CacheStatistics::getLastModifiedTime for this region and the entry.

If remote server put fails throwing back a CacheServerException or security exception, then local put is tried to rollback. However, if the entry has overflowed/evicted/expired then the rollback is aborted since it may be due to a more recent notification or update by another thread.

Parameters

key	the key smart pointer for which to create the entry in this region.
value	the value for the new entry, which may be NULLPTR meaning the new entry starts as if it had been locally invalidated.
aCallbackArgument	a user-defined parameter to pass to callback events triggered by this method. Can be NULLPTR. Should be serializable if passed to remote callback events

Exceptions

IllegalArgumentException	if key is NULLPTR or if the key, value, or aCallbackArgument do not meet serializability requirements
CacheWriterException	if CacheWriter aborts the operation
CacheListenerException	if CacheListener throws an exception
RegionDestroyedException	if region is no longer valid
CacheServerException	If an exception is received from the Java cache server. Only for Native Client regions.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the servers given to it For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
MessageExcepton	If the message received from server could not be handled. This will be the case when an unregistered typeId is received in the reply or reply is not well formed. More information can be found in the log.
TimeoutException	if the operation timed out
OutOfMemoryException	if no memory for new entry
EntryExistsException	if an entry with this key already exists

virtual void apache::geode::client::Region::destroy	(	const CacheableKeyPtr &	key,
		const UserDataPtr &	aCallbackArgument = `::apache::geode::client::NullSharedBase::s_instancePtr`
	)

pure virtual

Destroys the entry with the specified key, and provides a user-defined parameter object to any CacheWriter invoked in the process.

The same parameter is also passed to the CacheListener, if one is defined for this Region, invoked in the process. Destroy removes not only the value, but also the key and entry from this region.

The destroy is propogated to the Geode cache server to which it is connected with. If the destroy fails due to an exception on server throwing back CacheServerException or security exception, then the local entry is still destroyed.

Updates the CacheStatistics::getLastAccessedTime and CacheStatistics::getLastModifiedTime for this region and the entry.

Parameters

key	the key of the entry to destroy
aCallbackArgument	a user-defined parameter to pass to callback events triggered by this method. Can be NULLPTR. If it is sent on the wire, it has to be Serializable.

Exceptions

IllegalArgumentException	if key is NULLPTR
CacheWriterException	if CacheWriter aborts the operation
CacheListenerException	if CacheListener throws an exception
CacheServerException	If an exception is received from the Geode cache server. Only for Native Client regions.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the servers given to it For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.

TimeoutException	if the operation timed out
RegionDestroyedException	if the region is destroyed.
EntryNotFoundException	if the entry does not exist in this region.

	)

inline

Convenience method allowing key to be a const char*.

virtual void apache::geode::client::Region::destroyRegion ( const UserDataPtr & aCallbackArgument = ::apache::geode::client::NullSharedBase::s_instancePtr )

pure virtual

Destroys the whole region and provides a user-defined parameter object to any CacheWriter invoked in the process.

Destroy cascades to all entries and subregions. After the destroy, this region object cannot be used any more. Any attempt to use this region object will get a RegionDestroyedException exception.

The region destroy not only destroys the local region but also destroys the server region. However, if server region destroy fails throwing back CacheServerException or security exception, the local region is still destroyed.

Parameters

aCallbackArgument a user-defined parameter to pass to callback events triggered by this call. Can be NULLPTR. If it is sent on the wire, it has to be Serializable.

Exceptions

CacheWriterException	if CacheWriter aborts the operation; if this occurs some subregions may have already been successfully destroyed.
CacheListenerException	if CacheListener throws an exception; if this occurs some subregions may have already been successfully invalidated
CacheServerException	If an exception is received from the Java cache server. Only for Native Client regions.
NotConnectedException	if not connected to the geode system because the client cannot establish usable connections to any of the servers given to it. For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
MessageExcepton	If the message received from server could not be handled. This will be the case when an unregistered typeId is received in the reply or reply is not well formed. More information can be found in the log.
TimeoutException	if operation timed out

See also: invalidateRegion

virtual bool apache::geode::client::Region::existsValue	(	const char *	predicate,
		uint32_t	timeout = `DEFAULT_QUERY_RESPONSE_TIMEOUT`
	)

pure virtual

Executes the query on the server based on the predicate and returns whether any result exists.

Valid only for a Native Client region.

Parameters

predicate	The query predicate (just the WHERE clause) or the entire query to execute.
timeout	The time (in seconds) to wait for the response, optional. This should be less than or equal to 2^31/1000 i.e. 2147483.

Exceptions

IllegalArgumentException	If predicate is empty or timeout parameter is greater than 2^31/1000.
QueryException	if some query error occurred at the server.
NotConnectedException	if a server connection error occurs. For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
MessageExcepton	If the message received from server could not be handled. This will be the case when the reply is not well formed. More information can be found in the log.
TimeoutException	if operation timed out
CacheClosedException	if the cache has been closed

Returns: true if the result size is non-zero, false otherwise.

virtual CacheablePtr apache::geode::client::Region::get	(	const CacheableKeyPtr &	key,
		const UserDataPtr &	aCallbackArgument = `::apache::geode::client::NullSharedBase::s_instancePtr`
	)

pure virtual

Returns the value associated with the specified key, passing the callback argument to any cache loaders that are invoked in the operation.

If the value is not present locally then it is requested from the java server. If even that is unsuccessful then a local CacheLoader will be invoked if there is one. The value returned by get is not copied, so multi-threaded applications should not modify the value directly, but should use the update methods.

Updates the CacheStatistics::getLastAccessedTime, CacheStatistics::getHitCount, CacheStatistics::getMissCount, and CacheStatistics::getLastModifiedTime (if a new value is loaded) for this region and the entry.

Parameters

key	whose associated value is to be returned. The key Object must implement the equals and hashCode methods.
aCallbackArgument	an argument passed into the CacheLoader if loader is used. If it is sent on the wire, it has to be Serializable.

Exceptions

IllegalArgumentException	if key is NULLPTR or aCallbackArgument is not serializable and a remote CacheLoader needs to be invoked
CacheLoaderException	if CacheLoader throws an exception
CacheServerException	If an exception is received from the Java cache server. Only for Native Client regions.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the servers given to it. For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
MessageExcepton	If the message received from server could not be handled. This will be the case when an unregistered typeId is received in the reply or reply is not well formed. More information can be found in the log.
TimeoutException	if operation timed out
RegionDestroyedException	if the method is called on a destroyed region

virtual void apache::geode::client::Region::getAll	(	const VectorOfCacheableKey &	keys,
		HashMapOfCacheablePtr	values,
		HashMapOfExceptionPtr	exceptions,
		bool	addToLocalCache = `false`,
		const UserDataPtr &	aCallbackArgument = `::apache::geode::client::NullSharedBase::s_instancePtr`
	)

pure virtual

Gets values for an array of keys from the local cache or server.

If value for a key is not present locally then it is requested from the java server. The value returned is not copied, so multi-threaded applications should not modify the value directly, but should use the update methods.

Updates the CacheStatistics::getLastAccessedTime, CacheStatistics::getHitCount and CacheStatistics::getMissCount for this region and the entry.

Parameters

keys	the array of keys
values	Output parameter that provides the map of keys to respective values. It is ignored if NULLPTR, and when NULLPTR then at least the `addToLocalCache` parameter should be true and caching should be enabled for the region to get values into the region otherwise an `IllegalArgumentException` is thrown.
exceptions	Output parameter that provides the map of keys to any exceptions while obtaining the key. It is ignored if NULLPTR.
addToLocalCache	true if the obtained values have also to be added to the local cache

Since: 8.1

Parameters

aCallbackArgument an argument that is passed to the callback functions. It may be NULLPTR. Must be serializable if this operation is distributed.

Exceptions

IllegalArgumentException	If the array of keys is empty. Other invalid case is when the `values` parameter is NULLPTR, and either `addToLocalCache` is false or caching is disabled for this region.
CacheServerException	If an exception is received from the Java cache server while processing the request.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the given servers For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
RegionDestroyedException	If region destroy is pending.
TimeoutException	if operation timed out.
UnknownException	For other exceptions.

Updates the CacheStatistics::getLastAccessedTime and CacheStatistics::getLastModifiedTime for this region and the entry.

Parameters

key	the key of the entry to remove
value	the value of the key to remove, it can be NULLPTR.
aCallbackArgument	a user-defined parameter to pass to callback events triggered by this method. Can be NULLPTR. If it is sent on the wire, it has to be Serializable.

Exceptions

IllegalArgumentException	if key is NULLPTR
CacheWriterException	if CacheWriter aborts the operation
CacheListenerException	if CacheListener throws an exception
CacheServerException	If an exception is received from the Geode cache server. Only for Native Client regions.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the servers given to it For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
MessageExcepton	If the message received from server could not be handled. This will be the case when an unregistered typeId is received in the reply or reply is not well formed. More information can be found in the log.
TimeoutException	if the operation timed out
RegionDestroyedException	if the region is destroyed.

Returns: the boolean true if an entry(key, value)has been removed or false if an entry(key, value) has not been removed.

virtual void apache::geode::client::Region::removeAll	(	const VectorOfCacheableKey &	keys,
		const UserDataPtr &	aCallbackArgument = `::apache::geode::client::NullSharedBase::s_instancePtr`
	)

pure virtual

Removes all of the entries for the specified keys from this region.

The effect of this call is equivalent to that of calling destroy on this region once for each key in the specified collection. If an entry does not exist that key is skipped; EntryNotFoundException is not thrown.

Updates the CacheStatistics::getLastAccessedTime and CacheStatistics::getLastModifiedTime for this region and the entries.

Since: 8.1

Parameters

keys	the keys to remove from this region.
aCallbackArgument	an argument that is passed to the callback functions. It is ignored if NULLPTR. It must be serializable if this operation is distributed.

Exceptions

IllegalArgumentException	If the array of keys is empty.
CacheServerException	If an exception is received from the Java cache server while processing the request.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the given servers For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
RegionDestroyedException	If region destroy is pending.
TimeoutException	if operation timed out.
UnknownException	For other exceptions.

		const UserDataPtr &	aCallbackArgument = `::apache::geode::client::NullSharedBase::s_instancePtr`
	)

pure virtual

Removes the entry with the specified key and provides a user-defined parameter object to any CacheWriter invoked in the process.

The same parameter is also passed to the CacheListener and CacheWriter, if one is defined for this Region, invoked in the process. remove removes not only the value, but also the key and entry from this region.

The remove is propogated to the Geode cache server to which it is connected with. If the destroy fails due to an exception on server throwing back CacheServerException or security exception, then the local entry is still removed.

Updates the CacheStatistics::getLastAccessedTime and CacheStatistics::getLastModifiedTime for this region and the entry.

Parameters

key	the key of the entry to remove

Exceptions

IllegalArgumentException	if key is NULLPTR
CacheWriterException	if CacheWriter aborts the operation
CacheListenerException	if CacheListener throws an exception
CacheServerException	If an exception is received from the Geode cache server. Only for Native Client regions.
NotConnectedException	if it is not connected to the cache because the client cannot establish usable connections to any of the servers given to it For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException.
