gov.nih.mipav.view.renderer.J3D.model.structures.ModelTriangleMesh.Edge

Enclosing class:

ModelTriangleMesh

protected class ModelTriangleMesh.Edge
extends java.lang.Object

A representation of an edge for the vertex-edge-triangle table. This class stores the pair of vertex indices for the end points of the edge. The edges and are considered to be identical. To simplify comparisons, the class stores the ordered indices. The class extends Object to obtain support for hashing into a map of edges.

Constructor Detail

Edge

public Edge(int i0,
            int i1)

Constructs an edge in the table.

Parameters:

i0 - a vertex index for an end point

i1 - a vertex index for an end point

Method Detail

equals

public boolean equals(java.lang.Object kObject)

Support for hashing into a map of edges.

Overrides:

equals in class java.lang.Object

Parameters:

kObject - an edge for comparison to the current one

Returns:

true iff the edges are identical. Because the class stores ordered indices, it is not necessary to use the more expensive test (i0 == other.i0 && i1 == other.i1) || (i0 == other.i1 && i1 == other.i0).

hashCode

public int hashCode()

Support for hashing into a map of edges.

Overrides:

hashCode in class java.lang.Object

Returns:

the hash key for the edge
