DtSingleIntersectNetworkSegmentMetric Class Reference

DtSingleIntersectNetworkSegmentMetric is a metric for finding any (single) intersection of a specified segment. After the first intersection is found, all other computation is stopped, and the results are stored in the metric for later use by the user.

virtual void DtSingleIntersectNetworkSegmentMetric::initialize ( Coordinate_System *  cs )

virtual

Initialize the metric. Use this call to do any additional preparation/initialization before the metric can be used. The vector network calls this function every time a metric is about to be used.

Reimplemented from DtMetric.

bool DtSingleIntersectNetworkSegmentMetric::endpointsCoincidentAtXY ( const DtNetworkEdge &  edge1, const DtNetworkEdge &  edge2, DtReal  xValue, DtReal  yValue  ) const

protected

This method returns true if either endpoint of the first edge is coincident with either endpoint of the second edge at the x- and y- values specified.
