class FileProtocol from StepData inherits Protocol from StepData
---Purpose : A FileProtocol is defined as the addition of several already
-- existing Protocols. It corresponds to the definition of a
-- SchemaName with several Names, each one being attached to a
-- specific Protocol. Thus, a File defined with a compound Schema
-- is processed as any other one, once built the equivalent
-- compound Protocol, a FileProtocol
uses Type, CString, SequenceOfTransient,
Graph from Interface, Check from Interface,
Protocol from Interface, Protocol from StepData
is
Create returns mutable FileProtocol;
---Purpose : Creates an empty FileProtocol
Add (me : mutable; protocol : Protocol from StepData);
---Purpose : Adds a Protocol to the definition list of the FileProtocol
-- But ensures that each class of Protocol is present only once
-- in this list
NbResources (me) returns Integer is redefined;
---Purpose : Gives the count of Protocols used as Resource (can be zero)
-- i.e. the count of Protocol recorded by calling the method Add
Resource (me; num : Integer) returns Protocol from Interface is redefined;
---Purpose : Returns a Resource, given a rank. Here, rank of calling Add
TypeNumber (me; atype : any Type) returns Integer is redefined;
---Purpose : Returns a Case Number, specific of each recognized Type
-- Here, NO Type at all is recognized properly : all Types are
-- recognized by the resources
GlobalCheck (me; G : Graph; ach : in out Check)
returns Boolean is redefined;
---Purpose : Calls GlobalCheck for each of its recorded ressources
-- -- Specific for StepData -- --
SchemaName (me) returns CString is redefined;
---Purpose : Returns the Schema Name attached to each class of Protocol
-- To be redefined by each sub-class
-- Here, SchemaName returns "" (empty String)
-- was C++ : return const
fields
thecomps : SequenceOfTransient;
end FileProtocol;
