Detailed Description

This class encapsulates TDF_Transaction.

Constructor & Destructor Documentation

DDF_Transaction::DDF_Transaction ( )

Creates an empty transaction context, unable to be opened.

DDF_Transaction::DDF_Transaction ( const Handle< TDF_Data > &  aDF)

Creates a transaction context on <aDF>, ready to be opened.

DDF_Transaction::~DDF_Transaction ( )
inline

Member Function Documentation

void DDF_Transaction::Abort ( )

Aborts the transactions until AND including the current opened one.

Handle< TDF_Delta > DDF_Transaction::Commit ( const Standard_Boolean  withDelta = Standard_False)

Commits the transactions until AND including the current opened one.

Handle< TDF_Data > DDF_Transaction::Data ( ) const

Returns the Data from TDF.

Standard_Boolean DDF_Transaction::IsOpen ( ) const

Returns true if the transaction is open.

Standard_Integer DDF_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 DDF_Transaction::Transaction ( ) const

Returns the number of the transaction opened by <me>.
