org.onosproject.net.topology.AbstractPathService

All Implemented Interfaces:

PathService

public abstract class AbstractPathService
extends Object
implements PathService

Helper class for path service.

Class inheriting this must manually initialize topologyService and hostService fields.

Method Detail

getPaths

public Set<Path> getPaths(ElementId src,
                          ElementId dst,
                          LinkWeigher weigher)

Description copied from interface: PathService

Returns the set of all shortest paths between the specified source and destination network elements. The path is computed using the supplied edge-weight function.

Specified by:

getPaths in interface PathService

Parameters:

src - source element

dst - destination element

weigher - edge-weight entity

Returns:

set of all shortest paths between the two element

getKShortestPaths

public Stream<Path> getKShortestPaths(ElementId src,
                                      ElementId dst,
                                      LinkWeigher weigher)

Description copied from interface: PathService

Returns the k-shortest paths between source and destination devices.

Specified by:

getKShortestPaths in interface PathService

Parameters:

src - source device

dst - destination device

weigher - edge-weight entity

Returns:

stream of k-shortest paths

getDisjointPaths

public Set<DisjointPath> getDisjointPaths(ElementId src,
                                          ElementId dst,
                                          LinkWeigher weigher)

Description copied from interface: PathService

Returns the set of all disjoint shortest path pairs between the specified source and destination elements. The path is computed using the supplied edge-weight function.

Specified by:

getDisjointPaths in interface PathService

Parameters:

src - source device

dst - destination device

weigher - edge-weight entity

Returns:

set of all shortest paths between the two devices

getDisjointPaths

public Set<DisjointPath> getDisjointPaths(ElementId src,
                                          ElementId dst,
                                          LinkWeigher weigher,
                                          Map<Link,Object> riskProfile)

Description copied from interface: PathService

Returns the set of all disjoint shortest path pairs between the specified source and destination elements and taking into consideration the provided risk profile. The path is computed using the supplied edge-weight function.

Specified by:

getDisjointPaths in interface PathService

Parameters:
