Interface PairwiseCostCalculator

All Known Implementing Classes:

DefaultPairwiseCostCalculator

public interface PairwiseCostCalculator

This interface defines methods to calculate the pairwise costs between two sets of points.

Since:

Oracle Database 11g Release 2 (11.2)

Method Summary

boolean	calculate(PointOnNet[][] startPoints, PointOnNet[][] endPoints, LODNetworkConstraint constraint) Computes the pairwise costs between two sets of points.
Matrix<double[]>	getPairwiseCosts() Returns the pairwise costs that was computed when calculate was called.
Matrix<LogicalSubPath>	getPairwisePaths() Returns the pairwise paths that was computed when calculate was called.

Method Detail

calculate

boolean calculate(PointOnNet[][] startPoints,
                  PointOnNet[][] endPoints,
                  LODNetworkConstraint constraint)
                  throws LODNetworkException

Computes the pairwise costs between two sets of points.

Parameters:

startPoints - start point candidates

endPoints - end point candidates

constraint - network constraint

Returns:

true if the pairwise paths are also computed in addition to the pairwise costs; false otherwise

Throws:

LODNetworkException

getPairwisePaths

Matrix<LogicalSubPath> getPairwisePaths()

Returns the pairwise paths that was computed when calculate was called. Returns null if the pairwise paths were not computed.

Returns:

getPairwiseCosts

Matrix<double[]> getPairwiseCosts()

Returns the pairwise costs that was computed when calculate was called. The pairwise costs must have been computed when calculate was called.

Returns:
