Method Detail

getSource

public Vertex getSource()

Returns the source Vertex of the edge.

Specified by:

getSource in interface DirectedEdge

Returns:

The source Vertex.

getSink

public Vertex getSink()

Returns the sink Vertex of the edge.

Specified by:

getSink in interface DirectedEdge

Returns:

The sink Vertex.

getDirection

public int getDirection()

Returns the direction of the Edge

Specified by:

getDirection in interface DirectedEdge

toString

public String toString()

Description copied from class: EdgeImpl

Returns a String representation of the Edge. By default, the format is: fromVertex.toString() + "->" + toVertex.toString()

Overrides:

toString in class EdgeImpl

Returns:

The String representation of the Edge

clone

protected Object clone()

Creates a clone of this Edge. This calls the Edge constructor, thereby creating a new instance of Edge. However, the vertices in both endpoints of the Edge are not cloned.

Overrides:

clone in class EdgeImpl

Returns:

A clone of an instance of Edge.
