Open CASCADE Technology
6.5.4
|
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.

Public Member Functions | |
DEFINE_STANDARD_ALLOC | 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_AsciiString & | Name () const |
Returns the transaction name. | |
Standard_Boolean | IsOpen () const |
Returns true if the transaction is open. |
