public class PgGraph

extends PgElementSet

Graph over a two-dimensional domain.

Dimension of vertices in graph is equal to the sum of the dimension of domain and surface.

Connectivity of image surface and graph depends on connectivity of domain. Only the connectivity of the domain may change. Via the update mechanism the connectivity of image surface and graph are adjusted.

Method Detail

init

public void init()

Description copied from class: PgElementSet

Initialize and reset instance variables after call to super.init().

Overrides:

init in class PgElementSet

setSurfaces

public void setSurfaces(PgElementSet domain,
                        PgElementSet surface)

copy

public void copy(PgGeometry aGeom)

Description copied from class: PgElementSet

Copy instance variables by duplication, not by copying a reference.

Overrides:

update

public boolean update(java.lang.Object event)

Description copied from class: PgElementSet

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

Overrides:

Following copied from interface: jv.object.PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false
