Class ReferenceSessionEntryProcessor

java.lang.Object

com.hazelcast.map.AbstractEntryProcessor<String,T>

com.hazelcast.web.AbstractWebDataEntryProcessor<Integer>

com.hazelcast.web.ReferenceSessionEntryProcessor

All Implemented Interfaces:

com.hazelcast.map.EntryProcessor<String,Integer>, DataSerializable, IdentifiedDataSerializable, Serializable

public class ReferenceSessionEntryProcessor
extends AbstractWebDataEntryProcessor<Integer>

Increments the reference count, returning Boolean.FALSE if the entry does not exist and Boolean.TRUE otherwise.

This EntryProcessor is intended to be used to check whether a session is known to the cluster in preparation to create a local "copy". When Boolean.FALSE is returned, it means the session is not known and a new session should be created. Otherwise, if the entry already exists, the reference count is incremented and Boolean.TRUE is returned to indicate a "copy" should be made.
