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.

DEFINE_STANDARD_ALLOC	TDF_Transaction (const TCollection_AsciiString &aName="")

	TDF_Transaction (const Handle< TDF_Data > &aDF, const TCollection_AsciiString &aName="")
	Creates a transaction context on <aDF>, ready to be opened.
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_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.
Handle_TDF_Delta	Commit (const Standard_Boolean withDelta=Standard_False)
	Commits the transactions until AND including the current opened one.
void	Abort ()
	Aborts the transactions until AND including the current opened one.
