GeometryFilterImpl
public abstract class GeometryFilterImpl
Implements a geometry filter.
This filter implements a relationship - of some sort - between two geometry expressions. Note that this comparison does not attempt to restict its expressions to be meaningful. This means that it considers itself a valid filter as long as it contains two geometry sub-expressions. It is also slightly less restrictive than the OGC Filter specification because it does not require that one sub-expression be an geometry attribute and the other be a geometry literal.
In other words, you may use this filter to compare two geometries in the same feature, such as: attributeA inside attributeB? You may also compare two literal geometries, although this is fairly meaningless, since it could be reduced (ie. it is always either true or false). This approach is very similar to that taken in the FilterCompare class.
