Class MathListener

java.lang.Object

jvx.math.MathListener

Direct Known Subclasses:

MathCameraListener, MathPickListener, MathTimerListener, MathUpdateListener

public class MathListener
extends java.lang.Object

Superclass for all event listeners of JavaView supplies adapter functionality to invoke Mathematica functions whenever a JavaView listener method is invoked. This class contains the Math-Link and a hashtable for the method/function mapping.

Beside registration of Mathematica functions this class communicates with the Mathematica kernel and invokes the Mathematica function registered in the handler.

This class is provided as a convenience to simplify the writing of listeners. Subclasses do not implement the registration methods invoked by Mathematica to register handler commands and establishing of the kernel link.
