Method Summary

Modifier and Type	Method and Description
DefaultSingleSourceShortestPaths	clone()
void	setNetworkAnalyst(NetworkAnalyst analyst) This method allows caller to pass the network analyst object to this shortest path algorithm implementation, so that the algorithm can call the analysis functions provided by the network analyst, or access the network explorer associated with the network analyst.
LogicalSubPath[]	shortestPaths(PointOnNet[] startPoint, PointOnNet[][] endPoints, LODNetworkConstraint constraint, int direction) Returns the shortest paths from the start point (one of the start point candidates) to each set of end points (one of the end point candidates).
LogicalLightSubPath[]	shortestPathsLight(PointOnNet[] startPoint, PointOnNet[][] endPoints, LODNetworkConstraint constraint, int direction) Returns the light weight shortest paths from the start point (one of the start point candidates) to each set of end points (one of the end point candidates).

Description copied from interface: SingleSourceShortestPaths

Returns the shortest paths from the start point (one of the start point candidates) to each set of end points (one of the end point candidates).

Specified by:

shortestPaths in interface SingleSourceShortestPaths

Parameters:

startPoint - start point candidates

endPoints - array of end point candidates

constraint - network constraint

direction - NetworkExplorer.DIRECTION_FORWARD or NetworkExplorer.DIRECTION_BACKWARD

Returns:

Throws:

LODNetworkException

                                         throws LODNetworkException

Description copied from interface: SingleSourceShortestPaths

Returns the light weight shortest paths from the start point (one of the start point candidates) to each set of end points (one of the end point candidates).

Specified by:

shortestPathsLight in interface SingleSourceShortestPaths

Parameters:

startPoint - start point candidates

endPoints - array of end point candidates

constraint - network constraint

direction - NetworkExplorer.DIRECTION_FORWARD or NetworkExplorer.DIRECTION_BACKWARD

Returns:

Throws:

LODNetworkException

setNetworkAnalyst

public void setNetworkAnalyst(NetworkAnalyst analyst)

Description copied from interface: SingleSourceShortestPaths

This method allows caller to pass the network analyst object to this shortest path algorithm implementation, so that the algorithm can call the analysis functions provided by the network analyst, or access the network explorer associated with the network analyst. If network analyst is not needed by the shortest path algorithm, the algorithm can choose to do nothing with this method.

Specified by:

setNetworkAnalyst in interface SingleSourceShortestPaths

clone

public DefaultSingleSourceShortestPaths clone()

Specified by:

clone in interface SingleSourceShortestPaths
