public class EventsHandler
extends 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

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

handleCatchMessage

public void handleCatchMessage(SProcessDefinition processDefinition,
 SReceiveTaskDefinition receiveTaskDefinition,
 SReceiveTaskInstance receiveTaskInstance)
                        throws SBonitaException

Throws:

SBonitaException

handleEventSubProcess

public void handleEventSubProcess(SProcessDefinition sDefinition,
 SProcessInstance parentProcessInstance)
                           throws SBonitaException

Throws:

SBonitaException

unregisterEventSubProcess

public void unregisterEventSubProcess(SProcessDefinition sDefinition,
 SProcessInstance parentProcessInstance)
                               throws SBonitaException

Throws:

SBonitaException

handleThrowEvent

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

called when we reach a throw event in the flow of a process

Parameters:

processDefinition -

eventDefinition -

eventInstance -

Throws:

SBonitaException

handleThrowMessage

public void handleThrowMessage(SProcessDefinition processDefinition,
 SSendTaskDefinition sendTaskDefinition,
 SSendTaskInstance sendTaskInstance)
                        throws SMessageInstanceCreationException,
SDataInstanceException,
SExpressionException,
STransactionNotFoundException

Throws:

SMessageInstanceCreationException

SDataInstanceException

SExpressionException

STransactionNotFoundException

public boolean handlePostThrowEvent(SProcessDefinition sProcessDefinition,
 SEndEventDefinition sEndEventDefinition,
 SThrowEventInstance sThrowEventInstance,
 SFlowNodeInstance sFlowNodeInstance)
                             throws SBonitaException

Throws:

SBonitaException

handleThrowEvent

public void handleThrowEvent(SEventTriggerDefinition sEventTriggerDefinition)
                      throws SBonitaException

called when a BPM event is triggered by the API

Parameters:

sEventTriggerDefinition -

Throws:

SBonitaException

triggerCatchEvent

public void triggerCatchEvent(SWaitingEvent waitingEvent,
 Long triggeringElementID)
                       throws SBonitaException

Parameters:

waitingEvent -

triggeringElementID -

Throws:

SBonitaException

Throws:

SBonitaException

triggerCatchEvent

public void triggerCatchEvent(SEventTriggerType eventTriggerType,
 Long processDefinitionId,
 Long targetSFlowNodeDefinitionId,
