Class DefaultPairwiseShortestPaths

java.lang.Object
oracle.spatial.network.lod.DefaultPairwiseShortestPaths

public class DefaultPairwiseShortestPaths

extends java.lang.Object

This is the default pairwise shortest paths algorithm. It computes the pairwise shortest paths one by one using the input shortest path algorithm.

Since:

Oracle Database 11g Release 2 (11.2)

Constructor Summary

DefaultPairwiseShortestPaths(NetworkExplorer ne, LinkCostCalculator[] lccs, NodeCostCalculator[] nccs, ShortestPath spAlgorithm)
Consstruct a DefaultPairwiseSP instance.

Method Summary

void	setInitialAnalysisInfo(LODAnalysisInfo analysisInfo) Sets the initial analysis info.
Matrix<LogicalSubPath>	shortestPaths(PointOnNet[][] startPoints, PointOnNet[][] endPoints, LODNetworkConstraint constraint) Returns the pair-wise shortest paths between a set of candidate start points and end points.

Method Detail

setInitialAnalysisInfo

public void setInitialAnalysisInfo(LODAnalysisInfo analysisInfo)

Sets the initial analysis info. This method allows analysis info to be passed to subsequent analysis.

Parameters:

analysisInfo - analysis information

shortestPaths

public Matrix<LogicalSubPath> shortestPaths(PointOnNet[][] startPoints,
                                            PointOnNet[][] endPoints,
                                            LODNetworkConstraint constraint)
                                     throws LODNetworkException

Returns the pair-wise shortest paths between a set of candidate start points and end points.

Parameters:

startPoints - array of start candidates

endPoints - array of end candidates

constraint - network constraint

Returns:

Throws:

LODNetworkException
