public interface EdgeSegment
extends Serializable, ExternalIdable

EdgeSegment represents an edge in a particular (single) direction. Each edge has either one or two edge segments where each edge segment may have a more detailed geography than its parent edge

Method Detail

remove

boolean remove(DirectedVertex vertex)

Remove the vertex from the edge segment if it is either the up or downstream vertex

Parameters:

vertex - to remove

Returns:

true when successful, false otherwise

setUpstreamVertex

void setUpstreamVertex(DirectedVertex vertexToReplaceWith)

Set another upstream vertex.

Parameters:

vertexToReplaceWith - to use

getUpstreamVertex

DirectedVertex getUpstreamVertex()

isDirectionAb

boolean isDirectionAb()

check if edge segment runs from vertex a to b or b to a

Returns:

true when running from a to b, otherwise false

replace

default boolean replace(DirectedVertex vertexToReplace,
                        DirectedVertex vertexToReplaceWith)

Replace one of the vertices of the edge segment

Parameters:

vertexToReplace - the vertex to replace
