Method Details

directionOf

public static com.here.platform.location.inmemory.graph.Direction directionOf(Vertex vertex)

directionOf

public static com.here.platform.location.inmemory.graph.Direction directionOf(VertexIndex index)

toDirection

public static Vertex toDirection(Vertex vertex,
 com.here.platform.location.inmemory.graph.Direction direction)

Invert the vertex direction for vertex, if necessary.

toDirection

public static VertexIndex toDirection(VertexIndex index,
 com.here.platform.location.inmemory.graph.Direction direction)

Invert the vertex direction for index, if necessary.

invertDirection

public static VertexIndex invertDirection(VertexIndex index)

Calculate the index of the vertex associated with the same segment but pointing in the opposite direction from index.

invertDirection

public static Vertex invertDirection(Vertex vertex)

Returns the vertex in the opposite direction of travel.

Each topology segment is associated with two vertices, one for each direction. Given a vertex, that corresponds to a topology segment in a direction, this method returns the one in the opposite direction.
