Method Detail

getVertexA

Vertex getVertexA()

Returns the endpoint A of the edge.

Returns:

Vertex Endpoint A of the edge.

getVertexB

Vertex getVertexB()

Returns the endpoint B of the edge.

Returns:

Vertex Endpoint B of the edge.

getOppositeVertex

Vertex getOppositeVertex(Vertex v)

Returns the Vertex opposite to the specified Vertex in the edge.

Returns:

Vertex The Vertex object that is the opposite to the specifid Vertex. If the specified Vertex is not an endpoint of the edge, returns null.
