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

Method Detail

getFather

public PsUpdateIf getFather()

Get parent and do nothing else.

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
