Class ScaledNoder

java.lang.Object
- com.vividsolutions.jts.noding.ScaledNoder

All Implemented Interfaces:

Noder
```
public class ScaledNoder
extends 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.

    Description copied from interface: Noder
    
    Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.
    
    Specified by:
    
    getNodedSubstrings in interface Noder
    
    Returns:
    
    a Collection of SegmentStrings
  - computeNodes
```
public void computeNodes(Collection inputSegStrings)
```
    Description copied from interface: Noder
    
    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.
    
    Specified by:
    
    computeNodes in interface Noder
    
    Parameters:
    
    inputSegStrings - a collection of SegmentStrings to node
