Constructor Detail

• PostProcessing

  public PostProcessing​(GProp<?> initialDispatcher)

  Constructor with initial dispatcher.

  Parameters:

  initialDispatcher - The initial dispatcher, can be null.

Method Detail

• setInitialProperty

  public void setInitialProperty​(GProp<?> initialDispatcher)

  Assigns the initial sender property that should perform post processing of events. This method should only be called from the initial GProp that sends the event the first time. This is done from the GProp.onEvent method and should not be called elsewhere.

  Specified by:

  setInitialProperty in interface IPostEventProcessing

  Parameters:

  initialDispatcher - The initial dispatcher.

• addPostProcessor

  public void addPostProcessor​(EventListener postProcessor)

  Adds a post-event processor that will be called when the event has completed its notification process. This method can be called at any time during the event notification phase, but calls to this method when post-processing is executing is not going to change the post-processors, thus will the postProcessor not be called.

  Note: the post-processors are called no matter if the event has been canceled, so the processor may have to check the cancel state.

  Calling this method with the same postProcessor more than once does not add it again.

  Specified by:

  addPostProcessor in interface IPostEventProcessing

  Parameters:

  postProcessor - Processor to add.

  Throws:

  java.lang.NullPointerException - If the postProcessor is null.

• getPostProcessors

  public EventListener[] getPostProcessors​(GProp<?> dispatcher)

  Gets the post-processors.

  Specified by:

  getPostProcessors in interface IPostEventProcessing

  Parameters:

  dispatcher - The property retrieving the post-processors, null for none.

  Returns:

  An array of the post-processors to call after all normal event notification, null for none.

• hasPostProcessors

  public boolean hasPostProcessors​(GProp<?> dispatcher)

  Checks for presence of post processors.

  Parameters:

  dispatcher - The property retrieving the post-processors, null for none.

  Returns:

  true if post processors are present, false otherwise.

• execute

  public void execute​(GProp<?> dispatcher,
                      GEvent event)

  Executes all post processors for a dispatcher.
