DefaultEdge

public DefaultEdge()

Constructor for reflection

DefaultEdge

protected DefaultEdge(I targetVertexId,
                      E value)

Create the edge with final values. Don't call, use EdgeFactory instead.

Parameters:

targetVertexId - Desination vertex id.

value - Value of the edge.

Method Detail
