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 automatically aborted at the destruction of this object, at the closure of its scope. More...

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. | |
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. | |
void | DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=-1) const |
Dumps the content of me into the stream. | |
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 automatically 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::TDF_Transaction | ( | const TCollection_AsciiString & | aName = "" | ) |
Creates an empty transaction context, unable to be opened.
TDF_Transaction::TDF_Transaction | ( | const Handle< TDF_Data > & | aDF, |
const TCollection_AsciiString & | aName = "" ) |
Creates a transaction context on <aDF>, ready to be opened.

void TDF_Transaction::Abort | ( | ) |
Aborts the transactions until AND including the current opened one.
Handle< TDF_Delta > TDF_Transaction::Commit | ( | const Standard_Boolean | withDelta = Standard_False | ) |
Commits the transactions until AND including the current opened one.
void TDF_Transaction::DumpJson | ( | Standard_OStream & | theOStream, |
Standard_Integer | theDepth = -1 ) const |
Dumps the content of me into the stream.
Aborts all the transactions on <myDF> and sets <aDF> to build a transaction context on <aDF>, ready to be opened.
Standard_Boolean TDF_Transaction::IsOpen | ( | ) | const |
Returns true if the transaction is open.
const TCollection_AsciiString & TDF_Transaction::Name | ( | ) | const |
Returns the transaction name.
Standard_Integer TDF_Transaction::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_Integer TDF_Transaction::Transaction | ( | ) | const |
Returns the number of the transaction opened by <me>.
