public long triggeringProcessEvent(long processDefinitionKey,
                                   long processInstanceKey,
                                   long eventScopeKey,

                                   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:

processDefinitionKey - the process instance key of the event trigger

processInstanceKey - 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)
