GeometryItemDistance (JTS Topology Suite 1.20.0 API)

java.lang.Object
- org.locationtech.jts.index.strtree.GeometryItemDistance

All Implemented Interfaces:

ItemDistance
```
public class GeometryItemDistance
extends Object
implements ItemDistance
```
An ItemDistance function for items which are Geometrys, using the Geometry.distance(Geometry) method.
To make this distance function suitable for using to query a single index tree, the distance metric is anti-reflexive. That is, if the two arguments are the same Geometry object, the distance returned is Double.MAX_VALUE.

    Computes the distance between two Geometry items, using the Geometry.distance(Geometry) method.
    
    Specified by:
    
    distance in interface ItemDistance
    
    Parameters:
    
    item1 - an item which is a Geometry
    
    item2 - an item which is a Geometry
    
    Returns:
    
    the distance between the geometries
    
    Throws:
    
    ClassCastException - if either item is not a Geometry
