Public Member Functions
bool	Read (const occ::handle< Storage_BaseDriver > &theDriver)
	Reads the header data section from the container defined by theDriver. Returns true in case of success. Otherwise, one need to get an error code and description using ErrorStatus and ErrorStatusExtension functions correspondingly.

bool	Write (const occ::handle< Storage_BaseDriver > &theDriver)
	Writes the header data section to the container defined by theDriver. Returns true in case of success. Otherwise, one need to get an error code and description using ErrorStatus and ErrorStatusExtension functions correspondingly.

TCollection_AsciiString	CreationDate () const
	Return the creation date.

TCollection_AsciiString	StorageVersion () const
	Return the Storage package version.

TCollection_AsciiString	SchemaVersion () const
	Get the version of the schema.

void	SetApplicationVersion (const TCollection_AsciiString &aVersion)
	Set the version of the application.

	Add <theUserInfo> to the user information.

const NCollection_Sequence< TCollection_AsciiString > &	UserInfo () const
	Return the user information.

void	AddToComments (const TCollection_ExtendedString &aComment)
	Add <theUserInfo> to the user information.

const NCollection_Sequence< TCollection_ExtendedString > &	Comments () const
	Return the user information.

int	NumberOfObjects () const
	Returns the number of persistent objects.

Storage_Error	ErrorStatus () const
	Returns a status of the latest call to Read / Write functions.

TCollection_AsciiString	ErrorStatusExtension () const
	Returns an error message if any of the latest call to Read / Write functions.

void	ClearErrorStatus ()
	Clears error status.

void	SetNumberOfObjects (const int anObjectNumber)

void	SetStorageVersion (const TCollection_AsciiString &aVersion)

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.

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.
