Method Details

triggerEventSubProcess

public void triggerEventSubProcess(ExecutableStartEvent startEvent,
 long flowScopeElementInstanceKey,
 ProcessInstanceRecord recordValue,
 org.agrona.DirectBuffer variables)

triggeringProcessEvent

public long triggeringProcessEvent(long processDefinitionKey,
 long processInstanceKey,
 long eventScopeKey,
 org.agrona.DirectBuffer catchEventId,
 org.agrona.DirectBuffer variables)

Triggers a process by updating the state with a new ProcessEventIntent.TRIGGERING event.

NOTE: this method assumes that the caller already verified that the target can accept new events!

Parameters:

processDefinitionKey - the event's corresponding process definition key

processInstanceKey - the event's corresponding process instance key

eventScopeKey - the event's scope key, which used to index the trigger in EventScopeInstanceState

catchEventId - the ID of the element which should be triggered by the event

variables - the variables/payload of the event (can be empty)

Returns:

the key of the process event

processEventTriggered

public void processEventTriggered(long eventTriggerKey,
 long processDefinitionKey,
 long processInstanceKey,
 long eventScopeKey,
 org.agrona.DirectBuffer catchEventId)

Marks a process to be triggered by updating the state with a new ProcessEventIntent.TRIGGERED event.

Parameters:

processInstanceKey - the process instance key of the event trigger

processDefinitionKey - the process instance key of the event trigger

eventScopeKey - the event's scope key, which is used as identifier for the event trigger

catchEventId - the ID of the element which was triggered by the event

activateTriggeredEvent

public void activateTriggeredEvent(long processEventKey,
 ExecutableFlowElement triggeredEvent,
 long eventScopeKey,
 long flowScopeKey,
 ProcessInstanceRecord elementRecord,
 org.agrona.DirectBuffer variables)
