SpatialRelationOp (OpenJUMP 2.4.0 API)

java.lang.Object
- org.openjump.core.attributeoperations.SpatialRelationOp

```
public class SpatialRelationOp
extends Object
```
Contains methods to extract sets of features which fullfill some spatial criterion.
notes:
- use "intersects" only for polygon geometries (condition intersection area > 0)
- "contains" can be used for polygons and points (centroid from polygon is calculated)
