Detailed Description

Supports modification of certain region attributes after the region has been created.

It is required that the attributes be completely initialized using an AttributesFactory before creating the region. AttributesMutator can be applied to adjusting and tuning a subset of attributes that are modifiable at runtime.

The setter methods all return the previous value of the attribute.

Constructor & Destructor Documentation

gemfire::AttributesMutator::AttributesMutator ( const RegionPtr & region )

Internal constructor.

Use Region::getAttributesMutator() to acquire the mutator for a region.

Member Function Documentation

void gemfire::SharedBase::preserveSB ( ) const

inherited

Atomically increment reference count.

int32_t gemfire::SharedBase::refCount ( )

inlineinherited

Returns: the reference count

void gemfire::SharedBase::releaseSB ( ) const

inherited

Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.

void gemfire::AttributesMutator::setCacheListener ( const CacheListenerPtr & aListener )

Sets cache listener for region.

The previous cache listener will be replaced with aListener.

Parameters

aListener cache listener

void gemfire::AttributesMutator::setCacheListener	(	const char *	libpath,
		const char *	factoryFuncName
	)

Sets cache listener for region.

The previous cache listener will be replaced with a listener created using the factory function provided in the given library.

Parameters

libpath	path of the library containing cache listener factory function.
factoryFuncName	factory function for creating cache listener.

void gemfire::AttributesMutator::setCacheLoader ( const CacheLoaderPtr & aLoader )

Sets cache loader for region.

The previous cache loader will be replaced with aLoader.

Parameters

aLoader cache loader

void gemfire::AttributesMutator::setCacheLoader	(	const char *	libpath,
		const char *	factoryFuncName
	)

Sets cache loader for region.

The previous cache loader will be replaced with a loader created using the factory function provided in the given library.

Parameters

libpath	path of the library containing cache loader factory function.
factoryFuncName	factory function for creating cache loader.

void gemfire::AttributesMutator::setCacheWriter ( const CacheWriterPtr & aWriter )

Sets cache writer for region.

The previous cache writer will be replaced with aWriter.

Parameters

aWriter cache writer

void gemfire::AttributesMutator::setCacheWriter	(	const char *	libpath,
		const char *	factoryFuncName
	)

Sets cache writer for region.

The previous cache writer will be replaced with a writer created using the factory function provided in the given library.

Parameters

libpath	path of the library containing cache writer factory function.
factoryFuncName	factory function for creating cache writer.

int32_t gemfire::AttributesMutator::setEntryIdleTimeout ( int32_t idleTimeout )

Sets the idleTimeout duration for region entries.

Parameters

idleTimeout the idleTimeout in seconds for entries in this region.

Returns: the previous value.

Exceptions

IllegalStateException if the new idleTimeout changes entry expiration from disabled to enabled or enabled to disabled.

ExpirationAction::Action gemfire::AttributesMutator::setEntryIdleTimeoutAction ( ExpirationAction::Action action )

Set the idleTimeout Action for region entries.

Parameters

action the idleTimeout ExpirationAction::Action for entries in this region.

Returns: the previous value.

Sets the timeToLive duration for region entries.

Parameters

timeToLive the timeToLive in seconds for entries in this region.

Returns: the previous value.

Exceptions

IllegalStateException if the new timeToLive changes entry expiration from disabled to enabled or enabled to disabled.

ExpirationAction::Action gemfire::AttributesMutator::setEntryTimeToLiveAction ( ExpirationAction::Action action )

Set the timeToLive Action for region entries.

Parameters

action the timeToLive ExpirationAction::Action for entries in this region.

Returns: the previous value.

uint32_t gemfire::AttributesMutator::setLruEntriesLimit ( uint32_t entriesLimit )

Sets the Maximum entry count in the region before LRU eviction.

Parameters

entriesLimit the number of entries to allow.

Returns: the previous value.

Exceptions

IllegalStateException if the new entriesLimit changes LRU from disabled to enabled or enabled to disabled.

int32_t gemfire::AttributesMutator::setRegionIdleTimeout ( int32_t idleTimeout )

Sets the idleTimeout duration for the region itself.

Parameters

idleTimeout the ExpirationAttributes for this region idleTimeout

Returns: the previous value.

Exceptions

IllegalStateException if the new idleTimeout changes region expiration from disabled to enabled or enabled to disabled.

ExpirationAction::Action gemfire::AttributesMutator::setRegionIdleTimeoutAction ( ExpirationAction::Action action )

Set the idleTimeout Action for the region itself.

Parameters

action the idleTimeout ExpirationAction::Action for this region.

Returns: the previous value.

int32_t gemfire::AttributesMutator::setRegionTimeToLive ( int32_t timeToLive )

Sets the timeToLive duration for the region itself.

Parameters

timeToLive the ExpirationAttributes for this region timeToLive

Returns: the previous value.

Exceptions
