public interface MetricMesh<V>
extends CombinatoricMesh<V>

A mesh with edge length information.

This representation of a mesh conveys distance information along with the combinatorics of the mesh. It is suitably general to work for different geometries.

Method Detail

edgeLength

double edgeLength(V v1,
                  V v2)

Determine distance between adjacent vertices of the mesh.

The returned length need not necessarily be equal to the euclidean length as determined from the vertex coordinates, if such coordinates are known in the first place.

An implementation may throw any convenient RuntimeException if the vertices are not adjacent, or not part of this mesh, but it is not required to do so. The order of the arguments should be irrelevant.

Parameters:

v1 - one vertex of an edge

v2 - a second vertex of the same edge

Returns:

the distance between the two vertices

Throws:

RuntimeException - if the vertices are not adjacent
