Detailed Description

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.

Constructor & Destructor Documentation

◆ TDF_Transaction() [1/2]

TDF_Transaction::TDF_Transaction ( const TCollection_AsciiString & aName = "" )

Creates an empty transaction context, unable to be opened.

◆ TDF_Transaction() [2/2]

TDF_Transaction::TDF_Transaction	(	const Handle< TDF_Data > &	aDF,
		const TCollection_AsciiString &	aName = `""`
	)

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

◆ ~TDF_Transaction()

Member Function Documentation

◆ Abort()

void TDF_Transaction::Abort ( )

Aborts the transactions until AND including the current opened one.

◆ Commit()

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

Commits the transactions until AND including the current opened one.

◆ Data()

Handle< TDF_Data > TDF_Transaction::Data ( ) const

Returns the Data from TDF.

◆ DumpJson()

void TDF_Transaction::DumpJson	(	Standard_OStream &	theOStream,
		Standard_Integer	theDepth = `-1`
	)		const

Dumps the content of me into the stream.

◆ Initialize()

void TDF_Transaction::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.

◆ IsOpen()

Standard_Boolean TDF_Transaction::IsOpen ( ) const

Returns true if the transaction is open.

◆ Name()

const TCollection_AsciiString& TDF_Transaction::Name ( ) const

Returns the transaction name.

◆ Open()

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.

◆ Transaction()

Standard_Integer TDF_Transaction::Transaction ( ) const

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