void	Paste (const occ::handle< TDF_Attribute > &into, const occ::handle< TDF_RelocationTable > &RT) const override

	Dumps the minimum information about <me> on <aStream>.

Public Member Functions inherited from TDF_Attribute
virtual void	SetID (const Standard_GUID &)

virtual void	SetID ()
	Sets default ID defined in nested class (to be used for attributes having User ID feature).

const TDF_Label	Label () const
	Returns the label to which the attribute is attached. If the label is not included in a DF, the label is null. See Label. Warning: If the label is not included in a data framework, it is null. This function should not be redefined inline.

int	Transaction () const
	Returns the transaction index in which the attribute has been created or modified.

int	UntilTransaction () const
	Returns the upper transaction index until which the attribute is/was valid. This number may vary. A removed attribute validity range is reduced to its transaction index.

	Returns true if the attribute is valid; i.e. not a backuped or removed one.

bool	IsNew () const
	Returns true if the attribute has no backup.

void	ForgetAllAttributes (const bool clearChildren=true) const
	Forgets all the attributes attached to the label of <me>. Does it on the sub-labels if <clearChildren> is set to true. Of course, this method is compatible with Transaction & Delta mechanisms. Be careful that if <me> will have a null label after this call.

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.
