## Public Member Functions

Standard_EXPORT | TFunction_Function ()
const Standard_GUID & | GetDriverGUID () const
| Returns the GUID for this function's driver. .
Standard_EXPORT void | SetDriverGUID (const Standard_GUID &guid)
| Sets the driver for this function as that indentified by the GUID guid. .
Standard_Boolean | Failed () const
| Returns true if the execution failed .
Standard_EXPORT void | SetFailure (const Standard_Integer mode=0)
| Sets the failed index. .
Standard_Integer | GetFailure () const
| Returns an index of failure if the execution of this function failed. If this integer value is 0, no failure has occurred. //! Implementation of Attribute methods: =================================== .
Standard_EXPORT const Standard_GUID & | ID () const
| Returns the ID of the attribute. .
virtual Standard_EXPORT void | Restore (const Handle(TDF_Attribute)&with)
| Restores the backuped contents from <anattribute> into this one. It is used when aborting a transaction. .
virtual Standard_EXPORT void | Paste (const Handle(TDF_Attribute)&into, const Handle(TDF_RelocationTable)&RT) const

This method is different from the "Copy" one,
because it is used when copying an attribute from
a source structure into a target structure. This
method may paste the contents of <me> into
<intoattribute>.
The given pasted attribute can be full or empty of
its contents. But don't make a NEW! Just set the
contents!
It is possible to use <arelocationtable> to
get/set the relocation value of a source
attribute.
.

virtual Standard_EXPORT Handle_TDF_Attribute | NewEmpty () const
| Returns an new empty attribute from the good end type. It is used by the copy algorithm. .
virtual Standard_EXPORT void | References (const Handle(TDF_DataSet)&aDataSet) const
| Adds the first level referenced attributes and labels to <adataset>. For this, use the AddLabel or AddAttribute of DataSet. If there is none, do not implement the method. .
virtual Standard_EXPORT Standard_OStream & | Dump (Standard_OStream &anOS) const
| Dumps the minimum information about <me> on <astream>. .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const

## Static Public Member Functions

static Standard_EXPORT Handle_TFunction_Function | Set (const TDF_Label &L)
| Static methods: ============== //! Finds or Creates a function attribute on the label <l>. Returns the function attribute. .
static Standard_EXPORT Handle_TFunction_Function | Set (const TDF_Label &L, const Standard_GUID &DriverID)
| Finds or Creates a function attribute on the label <l>. Sets a driver ID to the function. Returns the function attribute. .
static Standard_EXPORT const Standard_GUID & | GetID ()
| Returns the GUID for functions. //! Returns a function found on the label. //! Instance methods: ================ .
