org.locationtech.jts.noding.SinglePassNoder
- All Implemented Interfaces:
Noder
- Direct Known Subclasses:
MCIndexNoder
,SimpleNoder
Base class for
Noder
s which make a single
pass to find intersections.
This allows using a custom SegmentIntersector
(which for instance may simply identify intersections, rather than
insert them).- Version:

Method Details

setSegmentIntersector
Sets the SegmentIntersector to use with this noder. A SegmentIntersector will normally add intersection nodes to the input segment strings, but it may not - it may simply record the presence of intersections. However, some Noders may require that intersections be added.- Parameters:
segInt
-
-
computeNodes
Computes the noding for a collection ofSegmentString
s. Some Noders may add all these nodes to the input SegmentStrings; others may only add some or none at all.- Specified by:
computeNodes
in interfaceNoder
- Parameters:
segStrings
- a collection ofSegmentString
s to node
-
getNodedSubstrings
Returns aCollection
of fully nodedSegmentString
s. The SegmentStrings have the same context as their parent.- Specified by:
getNodedSubstrings
in interfaceNoder
- Returns:
- a Collection of SegmentStrings
