Interface ZCameraListener

All Superinterfaces:

java.util.EventListener

All Known Implementing Classes:

ZCameraAdapter

public interface ZCameraListener

extends java.util.EventListener

ZCameraListener is an interface to support notification when changes occur to a ZCamera. Based on Swing's ComponentListener.

The class that is interested in processing a camera event either implements this interface (and all the methods it contains) or extends the abstract ZCameraAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with a ZCamera using the ZCamera's addCameraListener method. When the ZCamera's state changes, the relevant method in the listener object is invoked, and the ZCameraEvent is passed to it.

ZCamera events are provided for notification purposes ONLY; Jazz will automatically handle ZCamera state changes internally so that everything works properly regardless of whether a program registers a ZCameraListener or not.
