org.bonitasoft.engine.execution.event.EventsHandler

public class EventsHandler
extends java.lang.Object

Handle event depending on its type TODO * Move all code that instantiate process/execute flow node after a event was triggered here + make it call reachedCatchEvent * For event sub process: the instantiate process must cancel all activities then instantiate the process * the instantiate event subprocess method is like the start of the process executor but with less things: factorise it * check that there is no execution issues with event sub process (add more test) * add test for each kind of start event in event sub process * try to trigger event subprocess with multiple events

Method Detail

setProcessExecutor

public void setProcessExecutor(ProcessExecutor processExecutor)

handleCatchEvent

public void handleCatchEvent(SProcessDefinition processDefinition,
                             SEventDefinition eventDefinition,
                             SEventInstance eventInstance)
                      throws SBonitaException

called when a catchEvent is reached e.g. we are going on a catch event in the flow of a process This is different of trigger catch event: e.g. for a message handleCatchEvent will create the waiting event and triggerCatchEvent is called when the message is received

Parameters:

processDefinition -

eventDefinition -

eventInstance -

Throws:

SBonitaException
