Public Member Functions
	DDF_Transaction ()
	Creates an empty transaction context, unable to be opened.
	DDF_Transaction (const Handle< TDF_Data > &aDF)
	Creates 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.
	~DDF_Transaction ()
Handle< TDF_Data >	Data () const
	Returns the Data from TDF.
Standard_Integer	Transaction () const
	Returns the number of the transaction opened by <me>.
Standard_Boolean	IsOpen () const
	Returns true if the transaction is open.
Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.
Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.
virtual	~Standard_Transient ()
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.
Standard_Boolean	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.
Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.
virtual void	Delete () const
	Memory deallocator for transient classes.

Additional Inherited Members
typedef void	base_type
	Returns a type descriptor about this object.
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.
static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

This class encapsulates TDF_Transaction.

Constructor & Destructor Documentation

DDF_Transaction() [1/2]

DDF_Transaction::DDF_Transaction

(

)

Creates an empty transaction context, unable to be opened.

DDF_Transaction() [2/2]

DDF_Transaction::DDF_Transaction

(

const Handle< TDF_Data > &

aDF

)

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

Member Function Documentation

Abort()

void DDF_Transaction::Abort

(

)

Aborts the transactions until AND including the current opened one.

Commit()

Handle< TDF_Delta > DDF_Transaction::Commit

(

const Standard_Boolean

withDelta = Standard_False

)

Commits the transactions until AND including the current opened one.

Data()

Handle< TDF_Data > DDF_Transaction::Data

(

)

const

Returns the Data from TDF.

IsOpen()

Standard_Boolean DDF_Transaction::IsOpen

(

)

const

Returns true if the transaction is open.

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.

Transaction()

Standard_Integer DDF_Transaction::Transaction

(

)

const

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