Detailed Description
Wraps a Noder and transforms its input into the integer domain.
This is intended for use with Snap-Rounding noders, which typically are only intended to work in the integer domain. Offsets can be provided to increase the number of digits of available precision.
Member Function Documentation
◆ computeNodes()
|
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.
Implements geos::noding::Noder.
◆ getNodedSubstrings()
|
overridevirtual |
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.
Implements geos::noding::Noder.
