                       org.kie.api.runtime.rule.EntryPoint wmEntryPoint)

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 occurrence of this event

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

isEvent

public boolean isEvent()

Always returns true, since the EventFactHandle is only used for Events, and not for regular Facts

Specified by:

isEvent in interface InternalFactHandle

Overrides:

isEvent in class DefaultFactHandle

Returns:

getStartTimestamp

public long getStartTimestamp()

Returns the timestamp of the occurrence of this event.

Returns:

getDuration

public long getDuration()
