Detailed Description

Nodes a set of SegmentString using a index based on MonotoneChain and a SpatialIndex.

The SpatialIndex used should be something that supports envelope (range) queries efficiently (such as a Quadtree or STRtree).

Last port: noding/MCIndexNoder.java rev. 1.4 (JTS-1.7)

Member Function Documentation

void geos::noding::MCIndexNoder::computeNodes ( const std::vector< SegmentString * > & segStrings )

overridevirtual

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 a collection of SegmentStrings to node The caller remains responsible for releasing the memory associated with the SegmentStrings.

std::vector< std::unique_ptr< SegmentString > > geos::noding::MCIndexNoder::getNodedSubstrings ( )

inlineoverridevirtual

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

Returns: a std::vector of SegmentStrings (copies of input, if needs be). Caller is responsible to delete elements of container. This method may only be called once.
