## org.jbpm.process.instance.event.listeners
Class RuleAwareProcessEventLister

    java.lang.Object
      org.jbpm.process.instance.event.listeners.RuleAwareProcessEventLister

All Implemented Interfaces:
  EventListener, ProcessEventListener

    public class RuleAwareProcessEventLister

extends Object
implements ProcessEventListener

Process event listener that is responsible for managing process instance as fact so rules can reason over it. It ensure that process instance is inserted as soon as it starts and gets retracted as soon as process instance completes. In addition it updates process instance whenever process variable is updated.

Constructor Summary
`RuleAwareProcessEventLister()`

Method Summary
`void` | `afterNodeLeft(ProcessNodeLeftEvent event)` This listener method is invoked right after a node in a process instance has been left (which is when the node was completed, for example when it performed the task it was designed for).
`void` | `afterNodeTriggered(ProcessNodeTriggeredEvent event)` This listener method is invoked right after a node in a process instance has been triggered (which is when the node was entered, for example when an incoming connection triggered it).
`void` | `afterProcessCompleted(ProcessCompletedEvent event)` This listener method is invoked right after a process instance has been completed (or aborted).
`void` | `afterProcessStarted(ProcessStartedEvent event)` This listener method is invoked right after a process instance has been started.
`void` | `afterVariableChanged(ProcessVariableChangedEvent event)` This listener method is invoked right after the value of a process variable has been changed.
`void` | `beforeNodeLeft(ProcessNodeLeftEvent event)` This listener method is invoked right before a node in a process instance is being left (which is when the node is completed, for example when it has performed the task it was designed for).
`void` | `beforeNodeTriggered(ProcessNodeTriggeredEvent event)` This listener method is invoked right before a node in a process instance is being triggered (which is when the node is being entered, for example when an incoming connection triggers it).
`void` | `beforeProcessCompleted(ProcessCompletedEvent event)` This listener method is invoked right before a process instance is being completed (or aborted).
`void` | `beforeProcessStarted(ProcessStartedEvent event)` This listener method is invoked right before a process instance is being started.
`void` | `beforeVariableChanged(ProcessVariableChangedEvent event)` This listener method is invoked right before the value of a process variable is being changed.
`protected FactHandle` | `getProcessInstanceFactHandle(Long processInstanceId, KieRuntime kruntime)`
