class FileProtocol  from IGESData    inherits  Protocol  from IGESData

    ---Purpose : This class allows to define complex protocols, in order to
    --           treat various sub-sets (or the complete set) of the IGES Norm,
    --           such as Solid + Draw (which are normally independant), etc...
    --           While it inherits Protocol from IGESData, it admits
    --           UndefinedEntity too

uses Protocol from Interface

is

    Create returns FileProtocol;
    ---Purpose : Returns an empty FileProtocol

    Add (me : mutable; protocol : Protocol from IGESData);
    ---Purpose : Adds a resource

    NbResources (me) returns Integer  is redefined;
    ---Purpose : Gives the count of Resources : the count of Added Protocols

    Resource (me; num : Integer) returns Protocol from Interface  is redefined;
    ---Purpose : Returns a Resource, given a rank (rank of call to Add)
