void | computeNodes (std::vector< SegmentString * > *segStrings) override |
Computes the noding for a collection of SegmentStrings. | |
std::vector< SegmentString * > * | getNodedSubstrings () const override |
A noder which extracts all line segments as SegmentString. This enables fast overlay of geometries which are known to be already fully noded. In particular, it provides fast union of polygonal and linear coverages. Unioning a noded set of lines is an effective way to perform line merging and line dissolving.
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.

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.
