class Category from Interface
|
|
|
|
---Purpose : This class manages categories
|
|
-- A category is defined by a name and a number, and can be
|
|
-- seen as a way of rough classification, i.e. less precise than
|
|
-- a cdl type.
|
|
-- Hence, it is possible to dispatch every entity in about
|
|
-- a dozen of categories, twenty is a reasonable maximum.
|
|
--
|
|
-- Basically, the system provides the following categories :
|
|
-- Shape (Geometry, BRep, CSG, Features, etc...)
|
|
-- Drawing (Drawing, Views, Annotations, Pictures, Scketches ...)
|
|
-- Structure (Component & Part, Groups & Patterns ...)
|
|
-- Description (Meta-Data : Relations, Properties, Product ...)
|
|
-- Auxiliary (those which do not enter in the above list)
|
|
-- and some dedicated categories
|
|
-- FEA , Kinematics , Piping , etc...
|
|
-- plus Professional for other dedicated non-classed categories
|
|
--
|
|
-- In addition, this class provides a way to compute then quickly
|
|
-- query category numbers for an entire model.
|
|
-- Values are just recorded as a list of numbers, control must
|
|
-- then be done in a wider context (which must provide a Graph)

Create returns Category;
|
|
---Purpose : Creates a Category, with no protocol yet
|
|
|
|
Create (proto : Protocol) returns Category;
|
|
---Purpose : Creates a Category with a given protocol
|
|
|
|
Create (gtool : GTool) returns Category;
|
|
---Purpose : Creates a Category with a given GTool
|

|
|
SetProtocol (me : in out; proto : Protocol);
|
|
---Purpose : Sets/Changes Protocol
|
|
|
|
CatNum (me : in out; ent : Transient; shares : ShareTool) returns Integer;
|
|
---Purpose : Determines the Category Number for an entity in its context,
|
|
-- by using general service CategoryNumber
|
|
|
|
ClearNums (me : in out);
|
|
---Purpose : Clears the recorded list of category numbers for a Model
|
|
|
|
Compute (me : in out; model : InterfaceModel; shares : ShareTool);
|
|
---Purpose : Computes the Category Number for each entity and records it,
|
|
-- in an array (ent.number -> category number)
|
|
-- Hence, it can be queried by the method Num.
|
|
-- The Model itself is not recorded, this method is intended to
|
|
-- be used in a wider context (which detains also a Graph, etc)
|
|
|
|
Num (me; nument : Integer) returns Integer;
|
|
---Purpose : Returns the category number recorded for an entity number
|
|
-- Returns 0 if out of range
|
|
|
|
AddCategory (myclass; name : CString) returns Integer;
|
|
---Purpose : Records a new Category defined by its names, produces a number
|
|
-- New if not yet recorded
|
|
|
|
NbCategories (myclass) returns Integer;
|
|
---Purpose : Returns the count of recorded categories
|
|
|
|
Name (myclass; num : Integer) returns CString;
|
|
---Purpose : Returns the name of a category, according to its number
|
|
|
|
Number (myclass; name : CString) returns Integer;
|
|
---Purpose : Returns the number of a category, according to its name
|
|
|

|
Init (myclass);
|
|
---Purpose : Default initialisation
