All Implemented Interfaces:

java.lang.Cloneable, PsUpdateIf, java.io.Serializable

public class PwVectorField

extends PsObject

With this class one is allowed to create a vector field to a given geometry right from scrap.

Version:

Method Detail

init

public void init()

Description copied from class: PsObject

If instance has missing name then assign default name 'object_NUMBER' where number is the total number of already created instances.

Overrides:

init in class PsObject

setDisplay

public void setDisplay(PvDisplayIf disp)

update

public boolean update(java.lang.Object event)

Description copied from class: PsObject

Update all inspector panels, send update to all registered update listeners and finally update parent. Each of those updates has this object as event independent of the argument of this method.

Central update method of this object. Must be overwritten if this class receives unknown events, say, from new children. Any subclass must class invoke super.update(event) on all events it does handle itself.

Overrides:

update in class PsObject

Following copied from class: jv.object.PsObject
