Class FacetHandle<X extends Point_3>

java.lang.Object

Jcg.triangulations3D.FacetHandle<X>

public class FacetHandle<X extends Point_3>
extends java.lang.Object

A dummy class used to represent a triangulation facet as a pair (TriangulationDSCell_3, int). The integer parameter is the index of the vertex opposite to the facet in the cell. Note that no facet is stored in the triangulation data structure, as this information is redundant with the one provided by the cells themselves and their vertices.

Method Summary

Modifier and Type	Method and Description
TriangulationDSCell_3<X>	cell() returns a cell containing the facet.
boolean	equals(java.lang.Object o) tests equality between FaceHandles, which is defined by equality of their vertices.
int	hashCode() provides a hashing index for a FaceHandle, based on the hashing indices of its vertices.
boolean	hasVertex(TriangulationDSVertex_3<X> v) returns whether the current facet has v as vertex.
int	index() returns the index of the vertex opposite of the current fact in cell().
int	index(TriangulationDSVertex_3<X> v) returns the index of v in the current facet.
TriangulationDSVertex_3<X>	vertex(int index) returns the vertex of prescribed index in the facet.

FacetHandle

public FacetHandle(TriangulationDSCell_3<X> c,
                   int i)

Method Detail

cell

public TriangulationDSCell_3<X> cell()

returns a cell containing the facet.

index

public int index()

returns the index of the vertex opposite of the current fact in cell().

vertex

public TriangulationDSVertex_3<X> vertex(int index)

returns the vertex of prescribed index in the facet.

hasVertex

public boolean hasVertex(TriangulationDSVertex_3<X> v)

returns whether the current facet has v as vertex.

index

public int index(TriangulationDSVertex_3<X> v)

returns the index of v in the current facet. The pre-requisite is that v must be a vertex of the facet.

equals

public boolean equals(java.lang.Object o)

tests equality between FaceHandles, which is defined by equality of their vertices.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

provides a hashing index for a FaceHandle, based on the hashing indices of its vertices.

Overrides:

hashCode in class java.lang.Object
