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. More...

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 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.

Constructor & Destructor Documentation

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.

Member Function Documentation

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.

Handle< TDF_Data > TDF_Transaction::Data

(

)

const

Returns the Data from TDF.

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.

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>.
