Detailed Description

Geometry classes support the concept of applying a GeometryComponentFilter filter to the Geometry. The filter is applied to every component of the Geometry which is itself a Geometry. A GeometryComponentFilter filter can either record information about the Geometry or change the Geometry in some way. GeometryComponentFilter is an example of the Gang-of-Four Visitor pattern.
