Method Details

throwErrorEvent

public void throwErrorEvent(CatchEventAnalyzer.CatchEventTuple catchEventTuple)

Throws an error event to the given element instance/catch event pair. Only throws the event if the given element instance is exists and is accepting events, e.g. isn't terminating, wasn't interrupted, etc.

Parameters:

catchEventTuple - a tuple representing a catch event and its current instance

findErrorCatchEvent

public Either<Failure,CatchEventAnalyzer.CatchEventTuple> findErrorCatchEvent(org.agrona.DirectBuffer errorCode,
 BpmnElementContext context)

Finds the right catch event for the given error. This is done by going up through the scope hierarchy recursively until a matching catch event is found. If none are found, a failure is returned.

The returned CatchEventAnalyzer.CatchEventTuple can be used to throw the event via throwErrorEvent(CatchEventTuple).

Parameters:

errorCode - the error code of the error event

context - the current element context

Returns:

a valid CatchEventAnalyzer.CatchEventTuple if a catch event is found, or a failure otherwise
