Package com.wolfram.jlink

Class MathPropertyChangeListener

java.lang.Object
com.wolfram.jlink.MathListener
com.wolfram.jlink.MathPropertyChangeListener
All Implemented Interfaces:
java.beans.PropertyChangeListener, java.util.EventListener
public class MathPropertyChangeListener
extends MathListener
implements java.beans.PropertyChangeListener
This class lets you trigger a call into Mathematica on the occurrence of a particular event. Like all the MathXXXListener classes, it is intended to be used primarily from Mathematica, although it can be used from Java code as well.

In response to a PropertyChangeEvent, objects of this class send to Mathematica: 

     userFunc[thePropertyChangeEvent]
userFunc is specified as a string, either a function name or an expression (like a pure function "foo[#]&"), via the setHandler() method.

  • Constructor Summary

    Constructors 
    Constructor Description
    MathPropertyChangeListener()
    The constructor that is typically called from Mathematica.
    MathPropertyChangeListener​(KernelLink ml)
    You must use this constructor when using this class in a Java program, because you need to specify the KernelLink that will be used.
    MathPropertyChangeListener​(java.lang.String func)
    Because the PropertyChangeListener interface has only one method, propertyChange(), you can specify the Mathematica function to be called with this constructor, rather than having to separately call setHandler().

    • MathPropertyChangeListener

      public MathPropertyChangeListener()
      The constructor that is typically called from Mathematica.

    • MathPropertyChangeListener

      public MathPropertyChangeListener​(KernelLink ml)
      You must use this constructor when using this class in a Java program, because you need to specify the KernelLink that will be used.
      Parameters:
      ml - The link to which computations will be sent when PropertyChangeEvents arrive.

    • MathPropertyChangeListener

      public MathPropertyChangeListener​(java.lang.String func)
      Because the PropertyChangeListener interface has only one method, propertyChange(), you can specify the Mathematica function to be called with this constructor, rather than having to separately call setHandler(). Use this constructor from Mathematica code only.
      Parameters:
      func - The Mathematica function to be executed in response to a PropertyChangeEvent.
