Class SinglePassNoder

Hierarchy: Object , SinglePassNoder

All Implemented Interfaces: Noder

Direct Known Subclasses: SimpleNoder, MCIndexNoder

public abstract class SinglePassNoder
implements Noder

Base class for Noders 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).

public SinglePassNoder()

public SinglePassNoder(SegmentIntersector segInt)

public void setSegmentIntersector(SegmentIntersector segInt)

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 - segInt

public abstract abstract void computeNodes(Collection segStrings)

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.

Parameters:: segStrings - segStrings a collection of SegmentStrings to node

public abstract abstract Collection getNodedSubstrings()

Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Returns:: a Collection of SegmentStrings
