Class DefaultPairwiseCostCalculator

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

All Implemented Interfaces:

PairwiseCostCalculator

public class DefaultPairwiseCostCalculator

extends java.lang.Object

implements PairwiseCostCalculator

This is the default pairwise cost calculator. It calculates the pairwise costs using the input pairwise shortest path algorithm.

Since:

Oracle Database 11g Release 2 (11.2)

Constructor Summary

DefaultPairwiseCostCalculator(oracle.spatial.network.lod.PairwiseShortestPaths pwsp)
Constructs a default pairwise cost calculator.

Method Summary

boolean	calculate(PointOnNet[][] startPoints, PointOnNet[][] endPoints, LODNetworkConstraint constraint) Computes the pairwise shorest path and the pairwise costs using the pairwise shortest paths algorithm passed in to the constructor.
Matrix<double[]>	getPairwiseCosts() Returns the pairwise costs.
