author  Johann Sorel

Variables : -
Functions : getVertex1, getVertex2, getProperties, isLoop, getAdjacentVertices, isParallale


Get first vertex.
return  Vertex first edge vertex
Vertex getVertex1 ()


Get second vertex.
return  Vertex second edge vertex
Vertex getVertex2 ()


Get Properties attached to this edge.
return  Dictionary
Dictionary getProperties ()


A Loop is an edge which source and target vertex are the same.
return  true if edge is a loop
boolean isLoop ()


Return the adjacent vertex of two edges.
param  edge edge to test
return  0 : no adjacent vertices, 1 : first , 2 : second, 3 : both are adjacent
int getAdjacentVertices (Edge edge)


Two edge are parallale if they link the same vertices.
param  edge edge to test
return  true if edges are parallale
boolean isParallale (Edge edge)
