Class BoundarySegmentNoder

java.lang.Object
org.locationtech.jts.noding.BoundarySegmentNoder
All Implemented Interfaces:
Noder

public class BoundarySegmentNoder extends Object implements Noder
A noder which extracts boundary line segments as SegmentStrings. Boundary segments are those which are not duplicated in the input. It is appropriate for use with valid polygonal coverages.

No precision reduction is carried out. If that is required, another noder must be used (such as a snap-rounding noder), or the input must be precision-reduced beforehand.

    • computeNodes

      public void computeNodes(Collection segStrings)
      Description copied from interface: Noder
      Computes the noding for a collection of SegmentStrings. Some Noders may add all these nodes to the input SegmentStrings; others may only add some or none at all.
      Specified by:
      computeNodes in interface Noder
      Parameters:
      segStrings - a collection of SegmentStrings to node
    • getNodedSubstrings

      public Collection getNodedSubstrings()
      Description copied from interface: Noder
      Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.
      Specified by:
      getNodedSubstrings in interface Noder
      Returns:
      a Collection of SegmentStrings
