Public Member Functions
Standard_Integer	CaseNum (const Handle< Interface_FileReaderData > &data, const Standard_Integer num) const override
	Translate the Type of record <num> in <data> to a positive Case Number, or 0 if failed. Works with a StepReaderData, in which the Type of an Entity is defined as a String : Reads the RecordType <num> then calls CaseNum (this type) Warning : The methods CaseStep, StepType and Recognize, must be in phase (triplets CaseNum-StepType-Type of Object)

virtual Standard_Integer	CaseStep (const TCollection_AsciiString &atype) const =0
	Defines Case Numbers corresponding to the recognized Types Called by CaseNum (data,num) above for a Simple Type Entity Warning : CaseStep must give the same Value as Protocol does for the Entity type which corresponds to this Type given as a String.

virtual Standard_Integer	CaseStep (const TColStd_SequenceOfAsciiString &types) const
	Same a above but for a Complex Type Entity ("Plex") The provided Default recognizes nothing.

virtual Standard_Boolean	IsComplex (const Standard_Integer CN) const
	Returns True if the Case Number corresponds to a Complex Type ("Plex"). Remember that all possible combinations must be acknowledged to be processed Default is False for all cases. For a Protocol which defines possible Plexes, this method must be redefined.

virtual const TCollection_AsciiString &	StepType (const Standard_Integer CN) const =0
	Function specific to STEP, which delivers the StepType as it is recorded in and read from a File compliant with STEP. This method is symmetric to the method CaseStep. StepType can be different from Dynamic Type's name, but belongs to the same class of Object. Returns an empty String if <CN> is zero. Warning : For a Complex Type Entity, returns an Empty String (Complex Type must be managed by users)

virtual TCollection_AsciiString	ShortType (const Standard_Integer CN) const
	Function specific to STEP. Some STEP Types have a short form This method can be redefined to fill it By default, returns an empty string, which is then interpreted to take normal form from StepType.

virtual Standard_Boolean	ComplexType (const Standard_Integer CN, TColStd_SequenceOfAsciiString &types) const
	Function specific to STEP, which delivers the list of types which corresponds to a complex type. If <CN> is not for a complex type, this method returns False. Else it returns True and fills the list in alphabetic order. The default returns False. To be redefined as required.

void	Read (const Standard_Integer CN, const Handle< Interface_FileReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, const Handle< Standard_Transient > &ent) const override
	General Read Function, calls ReadStep.

virtual void	ReadStep (const Standard_Integer CN, const Handle< StepData_StepReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, const Handle< Standard_Transient > &ent) const =0
	Specific Read Function. Works with StepReaderData.

virtual void	WriteStep (const Standard_Integer CN, StepData_StepWriter &SW, const Handle< Standard_Transient > &ent) const =0
	Write Function, switched by CaseNum.

Public Member Functions inherited from Interface_ReaderModule
virtual Standard_Boolean	NewRead (const Standard_Integer casenum, const Handle< Interface_FileReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, Handle< Standard_Transient > &ent) const
	Specific operator (create+read) defaulted to do nothing. It can be redefined when it is not possible to work in two steps (NewVoid then Read). This occurs when no default constructor is defined : hence the result <ent> must be created with an effective definition from the reader. Remark : if NewRead is defined, Copy has nothing to do.

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.

Standard_Boolean	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.

Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.

virtual void	Delete () const
	Memory deallocator for transient classes.

Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.

Static Public Member Functions inherited from Standard_Transient
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.

static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

Detailed Description

Defines basic File Access Module (Recognize, Read, Write) That is : ReaderModule (Recognize & Read) + Write for StepWriter (for a more centralized description) Warning : A sub-class of ReadWriteModule, which belongs to a particular Protocol, must use the same definition for Case Numbers (give the same Value for a StepType defined as a String from a File as the Protocol does for the corresponding Entity)
