Constructor Detail

LineMergeDirectedEdge

public LineMergeDirectedEdge(Node from,
                     Node to,
                     Point directionPt,
                     boolean edgeDirection)

Constructs a LineMergeDirectedEdge connecting the from node to the to node.

Parameters:

directionPt - specifies this DirectedEdge's direction (given by an imaginary line from the from node to directionPt)

edgeDirection - whether this DirectedEdge's direction is the same as or opposite to that of the parent Edge (if any)

Method Detail

getNext

public LineMergeDirectedEdge getNext()

Returns the directed edge that starts at this directed edge's end point, or null if there are zero or multiple directed edges starting there.

Returns:

the directed edge
