public class PjHodge

extends PjProject

Study hodge splitting of discrete vector fields. An vector field is split in gradient and rotation free parts with a remaining harmonic component.

Version:

18.07.00, 1.10 revised (ep) Removed vector field calculation by use of PwVectorField.
06.06.00, 2.10 revised (ep) Removed splitting routine from project to PwHodge.
06.03.00, 2.00 revised (ep) Corrected updates and made various changes.
24.11.99, 1.00 created (kp).

public PjHodge()

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

start

public void start()

Description copied from class: PjProject

Method is invoked during loading of a project in JavaView.

If a project has an animation object, then the animation panel is shown when the project's this start() method is invoked during loading of the project. Use setAnimation(PsAnimation) to register an animation.

If auto fit is enabled then scenery is scaled to fit in each display.

Overrides:

start in class PjProject

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.start(), #isEnabledAutoFit(boolean)

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Overrides:

update in class PsObject

Following copied from interface: jv.object.PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false
