Class MidpointSplitPointFinder

java.lang.Object
  com.vividsolutions.jts.triangulate.MidpointSplitPointFinder

All Implemented Interfaces:

ConstraintSplitPointFinder

public class MidpointSplitPointFinder

extends java.lang.Object

implements ConstraintSplitPointFinder

A simple split point finder which returns the midpoint of the split segment. This is a default strategy only. Usually a more sophisticated strategy is required to prevent repeated splitting. Other points which could be used are:

• The projection of the encroaching point on the segment
• A point on the segment which will produce two segments which will not be further encroached
• The point on the segment which is the same distance from an endpoint as the encroaching point
