## 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

void geos::noding::ScaledNoder::computeNodes | ( | std::vector< SegmentString * > * | segStrings ) | `[virtual]`

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

Implements geos::noding::Noder.

std::vector<SegmentString*>* geos::noding::ScaledNoder::getNodedSubstrings | ( | ) | const`[virtual]`

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

Returns:
  a newly allocated std::vector of const SegmentStrings. Caller is responsible to delete it

Implements geos::noding::Noder.
