Interface CacheEntryModifiedEvent<K,V>

All Superinterfaces:

CacheEntryEvent<K,V>, Event<K,V>, TransactionalEvent<K,V>

All Known Implementing Classes:

EventImpl

public interface CacheEntryModifiedEvent<K,V>
extends CacheEntryEvent<K,V>

This event subtype is passed in to any method annotated with CacheEntryModified

The getValue() method's behavior is specific to whether the callback is triggered before or after the event in question. For example, if event.isPre() is true, then event.getValue() would return the old value, prior to modification. If event.isPre() is false, then event.getValue() would return new new value. If the event is creating and inserting a new entry, the old value would be null.
