Interface ZEvent

All Known Implementing Classes:

ZCameraEvent, ZGroupEvent, ZMouseEvent, ZTransformEvent, ZNodeEvent

public interface ZEvent

This interface ensures that the implementing event can dispatch itself without someone else needing to look at the events ID or type. This allows us to get ride of all fireEvent(SpecificEventType) methods and replace them with one fireEvent(ZEvent) method that is located in ZSceneGraphObject.

Method Summary

void	dispatchTo(java.lang.Object listener) This method should dispatch this event to the listener using this events ID code to determine what method in the listener to call.
java.lang.Class	getListenerType() Get the listener type for this event.
boolean	isConsumed() Returns true if this event has previously been consumed by a listener.
void	setSource(java.lang.Object aSource) Set the souce of this event.

Method Detail

dispatchTo

public void dispatchTo(java.lang.Object listener)

This method should dispatch this event to the listener using this events ID code to determine what method in the listener to call.

getListenerType

public java.lang.Class getListenerType()

Get the listener type for this event. This is used by fireEvent in ZSceneGraphObject to determine what listeners should receive this event.

isConsumed

public boolean isConsumed()

Returns true if this event has previously been consumed by a listener.

setSource

public void setSource(java.lang.Object aSource)

Set the souce of this event. As the event is fired up the tree the source of the event will keep changing to reflect the scenegraph object that is firing the event.
