TDF_Transaction Class Reference

This class offers services to open, commit or
abort a transaction in a more secure way than
using Data from TDF. If you forget to close a
transaction, it will be automaticaly aborted at
the destruction of this object, at the closure of
its scope.

In case of catching errors, the effect will be the
same: aborting transactions until the good current
one.

Standard_EXPORT	TDF_Transaction (const TCollection_AsciiString &aName="")
	Creates an empty transaction context, unable to be opened. .
Standard_EXPORT	TDF_Transaction (const Handle(TDF_Data)&aDF, const TCollection_AsciiString &aName="")
	Creates a transaction context on <adf>, ready to be opened. .
Standard_EXPORT void	Initialize (const Handle(TDF_Data)&aDF)
	Aborts all the transactions on <mydf> and sets <adf> to build a transaction context on <adf>, ready to be opened. .
Standard_EXPORT Standard_Integer	Open ()
	If not yet done, opens a new transaction on <mydf>. Returns the index of the just opened transaction. It raises DomainError if the transaction is already open, and NullObject if there is no current Data framework. .
Standard_EXPORT Handle_TDF_Delta	Commit (const Standard_Boolean withDelta=Standard_False)
	Commits the transactions until AND including the current opened one. .
Standard_EXPORT void	Abort ()
	Aborts the transactions until AND including the current opened one. .
	~TDF_Transaction ()
Handle_TDF_Data	Data () const
	Returns the Data from TDF. .
Standard_Integer	Transaction () const
	Returns the number of the transaction opened by <me>. .
Standard_EXPORT const TCollection_AsciiString &	Name () const
	Returns the transaction name. .
Standard_Boolean	IsOpen () const
	Returns true if the transaction is open. .
Private Member Functions
Standard_EXPORT	TDF_Transaction (const TDF_Transaction &aTrans)
	Private to avoid copy. .
