Method Detail

performDefaultOutgoingBehavior

public void performDefaultOutgoingBehavior(ActivityExecution activityExceution)

Performs the default outgoing BPMN 2.0 behavior, which is having parallel paths of executions for the outgoing sequence flow. More precisely: every sequence flow that has a condition which evaluates to true (or which doesn't have a condition), is selected for continuation of the process instance. If multiple sequencer flow are selected, multiple, parallel paths of executions are created.

performIgnoreConditionsOutgoingBehavior

public void performIgnoreConditionsOutgoingBehavior(ActivityExecution activityExecution)

Performs the default outgoing BPMN 2.0 behavior (@see performDefaultOutgoingBehavior(ActivityExecution)), but without checking the conditions on the outgoing sequence flow. This means that every outgoing sequence flow is selected for continuing the process instance, regardless of having a condition or not. In case of multiple outgoing sequence flow, multiple parallel paths of executions will be created.

performOutgoingBehavior

protected void performOutgoingBehavior(ActivityExecution execution,
                                       boolean checkConditions,
                                       boolean throwExceptionIfExecutionStuck,
                                       List<ActivityExecution> reusableExecutions)

Actual implementation of leaving an activity.

Parameters:

execution - The current execution context

checkConditions - Whether or not to check conditions before determining whether or not to take a transition.

throwExceptionIfExecutionStuck - If true, an ProcessEngineException will be thrown in case no transition could be found to leave the activity.

isAncestorCompensationThrowing

protected boolean isAncestorCompensationThrowing(ActivityExecution execution)
