Class PgEdgeStar

java.lang.Object

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 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 has changed to PiVector then method this#getSize() has been renamed to this#getValence() to avoid conflict PiVector#getSize().

See Also:

PiVector.toShortString()

getValence

public int getValence()

Get currently number of adjacent elements sharing this edge.

Since:

JavaView 3.96.026, replaces original method getSize() since conflict with PiVector#getSize().
