class ReadWriteModule from RWHeaderSection  inherits ReadWriteModule from StepData

	---Purpose : General module to read and write HeaderSection entities

uses Transient,

     AsciiString              from TCollection,
     Check                    from Interface,
     StepReaderData           from StepData,

is

	Create returns mutable ReadWriteModule from RWHeaderSection;

	CaseStep (me; atype : AsciiString from TCollection) returns Integer;
	---Purpose : associates a positive Case Number to each type of HeaderSection entity,
	-- given as a String defined in the EXPRESS form

	CaseStep(me; types : SequenceOfAsciiString from TColStd) returns Integer is redefined;
	---Purpose : associates a positive Case Number to each type of HeaderSection Complex entity,
	-- given as a String defined in the EXPRESS form

	IsComplex (me; CN : Integer) returns Boolean is redefined;
	---Purpose : returns True if the Case Number corresponds to a Complex Type

	StepType (me; CN : Integer) returns AsciiString from TCollection;
	---Purpose : returns a StepType (defined in EXPRESS form which belongs to a 
	-- Type of Entity, identified by its CaseNumber determined by Protocol
	---C++ : return const &
