All Implemented Interfaces:

Serializable, Cloneable, Comparable<org.drools.core.common.EventFactHandle>, javax.rules.Handle, org.drools.core.common.InternalFactHandle, org.drools.core.util.Entry<org.drools.core.common.DefaultFactHandle>, org.drools.core.util.LinkedListNode<org.drools.core.common.DefaultFactHandle>, org.kie.api.runtime.rule.FactHandle

public class Jsr94EventFactHandle
extends org.drools.core.common.EventFactHandle
implements javax.rules.Handle

The Drools implementation of the Handle interface which provides a marker interface for Drools-specific object identity mechanism. When using the StatefulRuleSession objects that are added to rule session state are identified using a Drools-supplied Handle implementation.

Handles are used to unambigiously identify objects within the rule session state and should not suffer many of the object identity issues that arise when using muliple class loaders, serializing StatefulRuleSessions, or using Object.equals or object1 == object2 reference equality.

Jsr94EventFactHandle

public Jsr94EventFactHandle(long id,
                            Object object,
                            long recency,
                            long timestamp,

                            org.kie.api.runtime.rule.SessionEntryPoint entryPoint)

Creates a new event fact handle.

Parameters:

id - this event fact handle ID

object - the event object encapsulated in this event fact handle

recency - the recency of this event fact handle

timestamp - the timestamp of the occurence of this event

duration - the duration of this event. May be 0 (zero) in case this is a primitive event.
