Member Function Documentation

UserDataPtr gemfire::EntryEvent::getCallbackArgument ( ) const

inline

Returns the callbackArgument passed to the method that generated this event.

See the Region interface methods that take a callbackArgument parameter.

CacheableKeyPtr gemfire::EntryEvent::getKey ( ) const

inline

Returns

the key this event describes.

CacheablePtr gemfire::EntryEvent::getNewValue ( ) const

inline

If the event is a destroy or invalidate operation, then the new value will be NULLPTR.

Returns

the updated value from this event

CacheablePtr gemfire::EntryEvent::getOldValue ( ) const

inline

If the prior state of the entry was invalid, or non-existent/destroyed, then the old value will be NULLPTR.

Returns

the old value in the cache.

RegionPtr gemfire::EntryEvent::getRegion ( ) const

inline

Returns

the region this event occurred in.

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.

bool gemfire::EntryEvent::remoteOrigin ( ) const

inline

If the event originated in a remote process, returns true.
