Interface PathService

public interface PathService

Service for obtaining pre-computed paths or for requesting computation of paths using the current topology snapshot.

Method Summary

Modifier and Type	Method and Description
Set<Path>	getPaths(ElementId src, ElementId dst) Returns the set of all shortest paths, precomputed in terms of hop-count, between the specified source and destination elements.
Set<Path>	getPaths(ElementId src, ElementId dst, LinkWeight weight) Returns the set of all shortest paths, computed using the supplied edge-weight entity, between the specified source and destination network elements.

Method Detail

getPaths

Set<Path> getPaths(ElementId src,
                   ElementId dst)

Returns the set of all shortest paths, precomputed in terms of hop-count, between the specified source and destination elements.

Parameters:

src - source element

dst - destination element

Returns:

set of all shortest paths between the two elements

getPaths

Set<Path> getPaths(ElementId src,

Returns the set of all shortest paths, computed using the supplied edge-weight entity, between the specified source and destination network elements.

Parameters:

src - source element

dst - destination element

weight - edge-weight entity

Returns:

set of all shortest paths between the two element
