Method Detail

setInitialAnalysisInfo

void setInitialAnalysisInfo(LODAnalysisInfo analysisInfo)

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

Parameters:

analysisInfo - analysis information

shortestPath

LogicalSubPath shortestPath(PointOnNet[] startPoints,
                            PointOnNet[] endPoints,
                            LODNetworkConstraint constraint)
                            throws LODNetworkException

Returns the shortest path between a set of candidate start points and end points.

Parameters:

startPoints - start candidates

endPoints - end candidates

constraint - network constraint

Returns:

Throws:

LODNetworkException

getLinkLevelSelector

LinkLevelSelector getLinkLevelSelector()
