Method Detail

doLeave

public void doLeave(ActivityExecution execution)

Subclasses that call leave() will first pass through this method, before the regular FlowNodeActivityBehavior.leave(ActivityExecution) is called.

Overrides:

doLeave in class FlowNodeActivityBehavior

isCompensationEventSubprocess

protected boolean isCompensationEventSubprocess(ActivityImpl activity)

createCompensateEventSubscription

protected void createCompensateEventSubscription(ActivityExecution execution,
                                     ActivityImpl compensationHandler)

propagateExceptionAsError

protected void propagateExceptionAsError(Exception exception,
                             ActivityExecution execution)
                                  throws Exception

Throws:

Exception

executeWithErrorPropagation

protected void executeWithErrorPropagation(ActivityExecution execution,
                               Callable<Void> toExecute)
                                    throws Exception

Takes an ActivityExecution and an Callable and wraps the call to the Callable with the proper error propagation. This method also makes sure that exceptions not caught by following activities in the process will be thrown and not propagated.

Parameters:

execution -

toExecute -

Throws:

Exception

propagateException

protected void propagateException(ActivityExecution execution,
                      Exception ex)
                           throws Exception

Decides how to propagate the exception properly, e.g. as bpmn error or "normal" error.

Parameters:

execution - the current execution

ex - the exception to propagate

Throws:

Exception - if no error handler could be found

checkIfCauseOfExceptionIsBpmnError

protected BpmnError checkIfCauseOfExceptionIsBpmnError(Throwable e)

Searches recursively through the exception to see if the exception itself or one of its causes is a BpmnError.

Parameters:

e - the exception to check

Returns:

the BpmnError that was the cause of this exception or null if no BpmnError was found

isTransactionNotActive

protected boolean isTransactionNotActive()

isProcessEngineExceptionWithoutCause

protected boolean isProcessEngineExceptionWithoutCause(Exception exception)

propagateBpmnError

protected void propagateBpmnError(BpmnError error,
                      ActivityExecution execution)
                           throws Exception

Throws:

Exception

propagateError

protected void propagateError(String errorCode,
                  String errorMessage,
                  Exception origException,
                  ActivityExecution execution)
                       throws Exception

Throws:

Exception

signal

public void signal(ActivityExecution execution,
          String signalName,
          Object signalData)
            throws Exception

Specified by:

signal in interface SignallableActivityBehavior

Overrides:

signal in class FlowNodeActivityBehavior

Throws:

Exception

signalCompensationDone

protected void signalCompensationDone(ActivityExecution execution)
