Class BoundaryNodeRule.Mod2BoundaryNodeRule

java.lang.Object
  com.vividsolutions.jts.algorithm.BoundaryNodeRule.Mod2BoundaryNodeRule

All Implemented Interfaces:

BoundaryNodeRule

Enclosing class:

BoundaryNodeRule

public static class BoundaryNodeRule.Mod2BoundaryNodeRule

extends java.lang.Object

implements BoundaryNodeRule

A BoundaryNodeRule specifies that points are in the boundary of a lineal geometry iff the point lies on the boundary of an odd number of components. Under this rule LinearRings and closed LineStrings have an empty boundary.

This is the rule specified by the OGC SFS, and is the default rule used in JTS.

Method Detail

isInBoundary

public boolean isInBoundary(int boundaryCount)

Description copied from interface: BoundaryNodeRule

Tests whether a point that lies in boundaryCount geometry component boundaries is considered to form part of the boundary of the parent geometry.

Specified by:

isInBoundary in interface BoundaryNodeRule

Parameters:

boundaryCount - the number of component boundaries that this point occurs in

Returns:

true if points in this number of boundaries lie in the parent boundary
