package Materials
---Purpose: This package is useful for creating Material objects,
-- which contain a sequence of physical properties. All
-- applications which request physical properties on a
-- given material, should reference this package.
--
-- A predefined sequence of materials is given by the
-- dictionary of materials, and the sequence of known
-- properties is given by the material definition.
--
-- Only the package methods are public, except the
-- DictionaryOfMaterials class which is called by the
-- method Material.

class Color;
class MaterialDefinition;
class MaterialsDictionary;
class FuzzyInstance instantiates FuzzyInstance from Dynamic(MaterialDefinition from Materials);
class Material;
class MtsSequence instantiates
Sequence from TCollection (Material from Materials);
class MaterialsSequence instantiates
HSequence from TCollection (Material from Materials, MtsSequence);
MaterialFile(afile : CString from Standard);
---Level: Public
---Purpose: Sets the location and the name of the file defining
-- the definition of a material, in term of properties.
MaterialsFile(afile : CString from Standard);
---Level: Public
---Purpose: Sets the location and the name of the file defining
-- the dictionary of materials.
MaterialsFile returns CString from Standard;
---Level: Internal
---Purpose: Returns the location and the name of the dictionary
-- file of materials.
DictionaryOfMaterials returns MaterialsDictionary from Materials;
---Level: Internal
---Purpose: Returns the dictionary of materials.The dictionary is
-- created at the first call to this method, or if the
-- dictionary is not up to date with respect to the file
-- date.
ExistMaterial(aName : CString from Standard) returns Boolean from Standard;
---Purpose: True if the materialofname aName exists ...
Material(amaterial : CString from Standard) returns Material from Materials;
---Level: Public
---Purpose: Retrieves from the dictionary the object material with
-- <amaterial> as name.
NumberOfMaterials returns Integer from Standard;
---Level: Public
---Purpose: Returns the number of materials previously stored in
-- the dictionary.
Material(anindex : Integer from Standard) returns Material from Materials;
---Level: Public
---Purpose: This method used with the previous one, allows the
-- exploration of all the dictionary. It returns a
-- Material instance.
