Class SinglePassNoder

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

All Implemented Interfaces:

Noder

Direct Known Subclasses:

MCIndexNoder, SimpleNoder
```
public abstract class SinglePassNoder
extends Object
implements Noder
```
Base class for Noders which make a single pass to find intersections. This allows using a custom SegmentIntersector (which for instance may simply identify intersections, rather than insert them).

- Method Detail
  - setSegmentIntersector
```
public void setSegmentIntersector(SegmentIntersector segInt)
```
    Sets the SegmentIntersector to use with this noder. A SegmentIntersector will normally add intersection nodes to the input segment strings, but it may not - it may simply record the presence of intersections. However, some Noders may require that intersections be added.
    
    Parameters:
    
    segInt -
  - computeNodes
```
public abstract void computeNodes(Collection segStrings)
```
    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:
    
    segStrings - a collection of SegmentStrings to node
  - getNodedSubstrings
```
public abstract Collection getNodedSubstrings()
```
    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
