Geometry classes support the concept of applying a Geometry filter to the Geometry.
In the case of GeometryCollection subclasses, the filter is applied to every element Geometry. A Geometry filter can either record information about the Geometry or change the Geometry in some way. Geometry filters implement the interface GeometryFilter. (GeometryFilter is an example of the Gang-of-Four Visitor pattern).
