The taxonomy of Axl abstract classes

The geometric types in Axl can be grouped into basic data types and abstract data types. The basic data types are comming with their implementation, providing tools for their construction and manipulations The abstract data types are interface classes and usally not specialized in the core of Axl. The specialization is provided by external plugins. We describe the taxonomy of these classes, which all derive from the generic class AxlAbstractData.

Abstract data are types of generic geometric objects which do not have necessarily an implementation.
