Detailed Description

This file contains the superclasses for GIS functors.

Each GIS function is split in two: a functor class (for internal use) and a function (for external use) that uses the functor. The functor provides the internal interface to GIS functions, and it may throw exceptions. Some functions may need a combination of different functors to implement the desired functionality.

The function, not the functor, is the interface to the rest of MySQL.
