Class ScaledNoder
java.lang.Object
com.vividsolutions.jts.noding.ScaledNoder
- All Implemented Interfaces:
- Noder
public class ScaledNoder
- extends java.lang.Object
- implements Noder
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.
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.

getNodedSubstrings
public java.util.Collection getNodedSubstrings()
- Description copied from interface:
Noder
- Returns a
Collection
of fully noded SegmentString
s.
The SegmentStrings have the same context as their parent.
- Specified by:
getNodedSubstrings
in interface Noder
- Returns:
- a Collection of SegmentStrings
computeNodes
public void computeNodes(java.util.Collection inputSegStrings)
- Description copied from interface:
Noder
- Computes the noding for a collection of
SegmentString
s.
Some Noders may add all these nodes to the input SegmentStrings;
others may only add some or none at all.
- Specified by:
computeNodes
in interface Noder
- Parameters:
inputSegStrings
- a collection of SegmentString
s to node
