All Implemented Interfaces:

java.lang.Runnable, PsUpdateIf

public class MathUpdateListener
extends MathListener
implements PsUpdateIf, java.lang.Runnable

Listener for update mechanism of JavaView to invoke Mathematica commands. The event contains information about the change JavaView object, often it contains the changed object.

Method Detail

getFather

public PsUpdateIf getFather()

Get parent and do nothing else.

Specified by:

getFather in interface PsUpdateIf

See Also:

setParent(PsUpdateIf), update(Object)

setParent

public void setParent(PsUpdateIf parent)

Set parent and do nothing else.

Specified by:

setParent in interface PsUpdateIf

Parameters:

parent - will receive events which this does not handle

See Also:

getFather(), update(Object)

update

public boolean update(java.lang.Object event)

Event handling method in the update mechanism calls handling method inside Mathematica to process the event.

Note, currently this method starts a new thread to let Mathematica work asyncronously. If this method is invoked while Mathematica is working then only the last request is used to initiate another Mathematica operation.

Specified by:

update in interface PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false
