33 //! This class manages categories
34 //! A category is defined by a name and a number, and can be
35 //! seen as a way of rough classification, i.e. less precise than
37 //! Hence, it is possible to dispatch every entity in about
38 //! a dozen of categories, twenty is a reasonable maximum.
40 //! Basically, the system provides the following categories :
41 //! Shape (Geometry, BRep, CSG, Features, etc...)
42 //! Drawing (Drawing, Views, Annotations, Pictures, Sketches ...)
43 //! Structure (Component & Part, Groups & Patterns ...)
44 //! Description (Meta-Data : Relations, Properties, Product ...)
45 //! Auxiliary (those which do not enter in the above list)
46 //! and some dedicated categories
47 //! FEA , Kinematics , Piping , etc...
48 //! plus Professional for other dedicated non-classed categories
50 //! In addition, this class provides a way to compute then quickly
51 //! query category numbers for an entire model.
52 //! Values are just recorded as a list of numbers, control must
53 //! then be done in a wider context (which must provide a Graph)
