jv.vecmath.P_Vector

jv.vecmath.PiVector

jv.geom.PgEdgeStar

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public final class PgEdgeStar
extends PiVector

Edge of an element set with indices to both endpoints, adjacent elements, and local index of a vertex in each element, whose neighbour refers to an element at this edge.

There may be more than two elements joining an edge.

Note, when superclass was changed to PiVector then method this#getSize() was renamed to this#getValence() to avoid conflict PiVector#getSize().

Version:

23.06.07, 3.10 revised (kp) m_maxValence added to avoid too many allocations.
02.07.06, 3.00 revised (kp) Superclass changed to PiVector to allow usage as PiVector [] array.
Note, method this#getSize() renamed to this#getValence() since conflict with superclass.
23.12.01, 2.10 revised (ep) Internationalization.
23.06.00, 2.00 revised (kp) Superclass changed to P_Vector to allow tagging.
02.04.00, 1.20 revised (kp) Allocate array of 2 during construction to avoid reallocation.
03.09.99, 1.10 revised (kp) Former inner class of PgElementSet converted to public class.
00.00.98, 1.00 created (kp)
