public interface DirectedEdge
extends Edge

Directed Edge interface connecting two vertices in a directional fashion. Each edge has one or two underlying edge segments in a particular direction which may carry additional information for each particular direction of the edge.

Method Detail

getVertexA

DirectedVertex getVertexA()

Vertex A of the edge

Specified by:

getVertexA in interface Edge

Returns:

vertex A

getVertexB

DirectedVertex getVertexB()

Vertex B of the edge

Specified by:

getVertexB in interface Edge

Returns:

vertex B

registerEdgeSegment

EdgeSegment registerEdgeSegment(EdgeSegment edgeSegment,
                                boolean directionAB)

Register EdgeSegment. If there already exists an edgeSegment for that direction it is replaced and returned. If the edge segment has no parent edge, this edge is set. If there is a discrepancy between the edge segment's parent edge and this edge a warning is issued and the edge segment is not registered

Parameters:

edgeSegment - the edgeSegment to be registered

directionAB - direction of travel

Returns:

replaced egeSegment (if any)

getEdgeSegmentAb

EdgeSegment getEdgeSegmentAb()

Edge segment in the direction from A to B

Returns:

edge segment AB

getEdgeSegmentBa

EdgeSegment getEdgeSegmentBa()

Edge segment in the direction from B to A

Returns:

edge segment BA

replace

void replace(EdgeSegment edgeSegmentToReplace,
             EdgeSegment edgeSegmentToReplaceWith)

replace passed in edge segment (if present) with the passed in one

Parameters:

edgeSegmentToReplace - the one to replace

edgeSegmentToReplaceWith - the one to replace it with

getEdgeSegment

default EdgeSegment getEdgeSegment(boolean directionAb)

Edge segment in the direction indicated

Parameters:

directionAb - direction of segment

Returns:

edge segment if present

hasEdgeSegmentBa

default boolean hasEdgeSegmentBa()

Verify if edge segment BA exists

Returns:

true if present, false otherwise

hasEdgeSegmentAb

default boolean hasEdgeSegmentAb()

Verify if edge segment BA exists

Returns:

true if present, false otherwise

getEdgeSegments

default Collection<? extends EdgeSegment> getEdgeSegments()

collect all edge segments available on the edge

Returns:

available edge segments
