Class BoundaryNodeRule.Mod2BoundaryNodeRule

  • All Implemented Interfaces:
    BoundaryNodeRule
    Enclosing interface:
    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.

        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
