## org.drools.event.process
Class DefaultProcessEventListener

    java.lang.Object
      org.drools.event.process.DefaultProcessEventListener

All Implemented Interfaces:
  EventListener, ProcessEventListener

    public class DefaultProcessEventListener

extends Object
implements ProcessEventListener

Constructor Summary
`DefaultProcessEventListener()`

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.
