Public Member Functions
	BinMDF_DerivedDriver (const Handle< TDF_Attribute > &theDerivative, const Handle< BinMDF_ADriver > &theBaseDriver)
	Creates a derivative persistence driver for theDerivative attribute by reusage of theBaseDriver.
virtual Handle< TDF_Attribute >	NewEmpty () const override
	Creates a new instance of the derivative attribute.
virtual Standard_Boolean	Paste (const BinObjMgt_Persistent &theSource, const Handle< TDF_Attribute > &theTarget, BinObjMgt_RRelocationTable &theRelocTable) const override
	Reuses the base driver to read the base fields.
virtual void	Paste (const Handle< TDF_Attribute > &theSource, BinObjMgt_Persistent &theTarget, BinObjMgt_SRelocationTable &theRelocTable) const override
	Reuses the base driver to store the base fields.
Public Member Functions inherited from BinMDF_ADriver
virtual const Handle< Standard_Type > &	SourceType () const
	Returns the type of source object, inheriting from Attribute from TDF.
const TCollection_AsciiString &	TypeName () const
	Returns the type name of the attribute object.
const Handle< Message_Messenger > &	MessageDriver () const
	Returns the current message driver of this driver.
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.

Detailed Description

A universal driver for the attribute that inherits another attribute with ready to used persistence mechanism implemented (already has a driver to store/retrieve).

Constructor & Destructor Documentation

BinMDF_DerivedDriver()

BinMDF_DerivedDriver::BinMDF_DerivedDriver ( const Handle< TDF_Attribute > & theDerivative, const Handle< BinMDF_ADriver > & theBaseDriver )

inline

Creates a derivative persistence driver for theDerivative attribute by reusage of theBaseDriver.

Parameters

theDerivative	an instance of the attribute, just created, detached from any label
theBaseDriver	a driver of the base attribute, called by Paste methods
