com.vividsolutions.jts.triangulate.NonEncroachingSplitPointFinder

All Implemented Interfaces:

ConstraintSplitPointFinder

public class NonEncroachingSplitPointFinder
extends Object
implements ConstraintSplitPointFinder

A strategy for finding constraint split points which attempts to maximise the length of the split segments while preventing further encroachment. (This is not always possible for narrow angles).
