Interface MuleEvent

All Known Implementing Classes:
  DefaultMuleEvent

    public interface MuleEvent

`MuleEvent` represents any data event occuring in the Mule environment. All data sent or received within the mule environment will be passed between components as an MuleEvent.

The MuleEvent holds a MuleMessage payload and provides helper methods for obtaining the data in a format that the receiving Mule component understands. The event can also maintain any number of properties that can be set and retrieved by Mule components.

  `MuleMessage`

### isStopFurtherProcessing

    boolean isStopFurtherProcessing()

  Determines whether the default processing for this event will be executed. By default, the Mule server will route events according to a components configuration. The user can override this behaviour by obtaining a reference to the MuleEvent context, either by implementing `org.mule.api.lifecycle.Callable` or calling `RequestContext.getEventContext` to obtain the MuleEventContext for the current thread. The user can programmatically control how events are dispached.

    Returns true is the user has set stopFurtherProcessing.

    `MuleContext`, `MuleEventContext`, `Callable`

### setStopFurtherProcessing

    void setStopFurtherProcessing(boolean stopFurtherProcessing)

  Determines whether the default processing for this event will be executed. By default, the Mule server will route events according to a components configuration. The user can override this behaviour by obtaining a reference to the MuleEvent context, either by implementing `org.mule.api.lifecycle.Callable` or calling `RequestContext.getEventContext` to obtain the MuleEventContext for the current thread. The user can programmatically control how events are dispached.

  Parameters:
    `stopFurtherProcessing` - the value to set.

### isSynchronous

    boolean isSynchronous()

  Determines whether the was sent synchrounously or not

### setSynchronous

    void setSynchronous(boolean value)

  Determines whether the was sent synchrounously or not

  Parameters:
    `value` - true if the event is synchronous

### getTimeout

    int getTimeout()

  The number of milliseconds to wait for a return event when running synchronously. 0 wait forever -1 try and receive, but do not wait or a positive millisecond value

  Returns:
    the event timeout in milliseconds

### setTimeout
