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 ()=default
	Destructor must be virtual.

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

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

bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.

bool	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.

bool	IsKind (const char *const 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.

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

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

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

Protected Member Functions
virtual int	ReadSubTree (Standard_IStream &theIS, const TDF_Label &theData, const occ::handle< PCDM_ReaderFilter > &theFilter, const bool &theQuickPart, const bool theReadMissing, const Message_ProgressRange &theRanges=Message_ProgressRange())
	Read the tree from the stream <theIS> to <theLabel>

virtual void	ReadSection (BinLDrivers_DocumentSection &theSection, const occ::handle< CDM_Document > &theDoc, Standard_IStream &theIS)
	define the procedure of reading a section to file.

virtual void	ReadShapeSection (BinLDrivers_DocumentSection &theSection, Standard_IStream &theIS, const bool isMess=false, const Message_ProgressRange &theRange=Message_ProgressRange())
	define the procedure of reading a shapes section to file.

virtual void	CheckShapeSection (const Storage_Position &thePos, Standard_IStream &theIS)
	checks the shapes section can be correctly retrieved.

virtual void	Clear ()
	clears the reading-cash data in drivers if any.

virtual bool	CheckDocumentVersion (const int theFileVersion, const int theCurVersion)
	Check a file version(in which file was written) with a current version. Redefining this method is a chance for application to read files written by newer applications. The default implementation: if the version of the file is greater than the current or lesser than 2, then return false, else true.

virtual void	EnableQuickPartReading (const occ::handle< Message_Messenger > &, bool)
	Enables reading in the quick part access mode.

Static Protected Member Functions
static bool	IsQuickPart (const int theFileVer)
	Return true if retrieved document allows to read parts quickly.
