ScaledNoder class
Wraps a {@link 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.
Clients should be aware that rescaling can involve loss of precision, which can cause zero-length line segments to be created. These in turn can cause problems when used to build a planar graph. This situation should be checked for and collapsed segments removed if necessary.

Methods
-
computeNodes(
List inputSegStrings) → void -
Computes the noding for a collection of {@link SegmentString}s.
Some Noders may add all these nodes to the input SegmentStrings;
others may only add some or none at all.
override
-
getNodedSubstrings(
) → List -
Returns a {@link List} of fully noded {@link SegmentString}s.
The SegmentStrings have the same context as their parent.
override
-
isIntegerPrecision(
) → bool -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

rescale(
List segStrings) → void -
rescaleCoords(
List< Coordinate> pts) → void -
scale(
List segStrings) → List -
scaleCoords(
List< Coordinate> pts) → List<Coordinate> -
toString(
) → String -
A string representation of this object.
