start or end.

Get the graph which contains this vertex.
return  Graph
Graph getGraph ()

Two vertices are adjacent when an edge links them.
param  vertex vertex to test
return  true if current vertex is adjacent with given vertex.
boolean isAdjacent (Vertex vertex)


The degree of a vertex is the number of edges ends which match this vertex.
return  int degree
int getDegree ()


The degree of a vertex is the number of edges which start by this vertex.
return  int degree
