Class SyntheticEventFilter

java.lang.Object

com.hazelcast.map.impl.SyntheticEventFilter

All Implemented Interfaces:

DataSerializable, EventFilter

public class SyntheticEventFilter
extends Object
implements EventFilter, DataSerializable

Wrapper class for a filter which does not want to receive synthetic events.

Synthetic events are caused by map internals such as eviction or expiration; other events are natural events like an explicit call to IMap.put(K, V) or IMap.evict(K).

This event filter is used to prevent near cache evictions caused by internal eviction or expiration operations in IMap, since near cache should use its own eviction/expiration mechanism, this filter helps to provide right near cache behavior.
