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.

 TDF_Transaction (const TCollection_AsciiString &aName="")
 Creates an empty transaction context, unable to be
opened.

 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.


 ~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>.


const TCollection_AsciiStringName () const
 Returns the transaction name.


Standard_Boolean IsOpen () const
 Returns true if the transaction is open.
