Detailed Description

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.

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.
