All Implemented Interfaces:

DecorablePosition<E>, Edge<E>, Map<Object,Object>, Position<E>

Enclosing class:

AdjacencyListGraph<V,E>

protected class AdjacencyListGraph.MyEdge<E>
extends AdjacencyListGraph.MyPosition<E>
implements Edge<E>

Implementation of an edge for an undirected adjacency list graph. Each edge stores its endpoints (end vertices), its positions within the incidence containers of its endpoints, and position in the edge container of the graph.

Field Detail

endVertices

protected AdjacencyListGraph.MyVertex<V>[] endVertices

The end vertices of the edge.

Inc

protected Position<Edge<E>>[] Inc

The positions of the entries for the edge in the incidence containers of the end vertices.

loc

protected Position<Edge<E>> loc

The position of the edge in the edge container of the graph.

Method Detail

endVertices

public AdjacencyListGraph.MyVertex<V>[] endVertices()

Returns the end vertices of the edge. There are always two elements in the returned array.

incidences

public Position<Edge<E>>[] incidences()

Returns the positions of the edge in the incidence containers of its end vertices. The returned array always contains two elements.

setIncidences

public void setIncidences(Position<Edge<E>> pv,
                          Position<Edge<E>> pw)

Sets the positions of the edge in the incidence containers of its end vertices.

location

public Position<Edge<E>> location()

Returns the position of the edge in the edge container of the graph.

setLocation

public void setLocation(Position<Edge<E>> p)

Sets the position of the edge in the edge container of the graph.

toString

public String toString()

Returns a string representation of the edge via a tuple of vertices.

Overrides:
