 Returns an new empty attribute from the good end type. It is used by the copy algorithm.

virtual Standard_Boolean BeforeUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False) override
 Something to do before applying <anAttDelta>. The returned status says if AfterUndo has been performed (true) or if this callback must be called once again further (false). If <forceIt> is set to true, the method MUST perform and return true. Does nothing by default and returns true.

- Public Member Functions inherited from TDF_Attribute
virtual void SetID (const Standard_GUID &)
 Sets specific ID of the attribute (supports several attributes of one type at the same label feature).
 
virtual void SetID ()
 Sets default ID defined in nested class (to be used for attributes having User ID feature).
 
const TDF_Label Label () const
 Returns the label to which the attribute is attached. If the label is not included in a DF, the label is null. See Label. Warning If the label is not included in a data framework, it is null. This function should not be redefined inline.
 
Standard_Integer Transaction () const
 Returns the transaction index in which the attribute has been created or modified.
 
Standard_Integer UntilTransaction () const
 Returns the upper transaction index until which the attribute is/was valid. This number may vary. A removed attribute validity range is reduced to its transaction index.
 
Standard_Boolean IsValid () const
 Returns true if the attribute is valid; i.e. not a backuped or removed one.
 
Standard_Boolean IsNew () const
 Returns true if the attribute has no backup.
 
Standard_Boolean IsForgotten () const
 Returns true if the attribute forgotten status is set.
 
Standard_Boolean IsAttribute (const Standard_GUID &anID) const
 Returns true if it exists an associated attribute of <me> with <anID> as ID.
 
Standard_Boolean FindAttribute (const Standard_GUID &anID, Handle< TDF_Attribute > &anAttribute) const
 Finds an associated attribute of <me>, according to <anID>. the returned <anAttribute> is a valid one. The method returns True if found, False otherwise. A removed attribute cannot be found using this method.
 
template<class T >
Standard_Boolean FindAttribute (const Standard_GUID &theID, Handle< T > &theAttr) const
 Safe variant for arbitrary type of argument.
 
void AddAttribute (const Handle< TDF_Attribute > &other) const
 Adds an Attribute <other> to the label of <me>.Raises if there is already one of the same GUID fhan <other>.
 
Standard_Boolean ForgetAttribute (const Standard_GUID &aguid) const
 Forgets the Attribute of GUID <aguid> associated to the label of <me>. Be careful that if <me> is the attribute of <guid>, <me> will have a null label after this call. If the attribute doesn't exist returns False. Otherwise returns True.
 
void ForgetAllAttributes (const Standard_Boolean clearChildren=Standard_True) const
 Forgets all the attributes attached to the label of <me>. Does it on the sub-labels if <clearChildren> is set to true. Of course, this method is compatible with Transaction & Delta mechanisms. Be careful that if <me> will have a null label after this call.
 
virtual Standard_Boolean AfterRetrieval (const Standard_Boolean forceIt=Standard_False)
 Something to do AFTER creation of an attribute by persistent-transient translation. The returned status says if AfterUndo has been performed (true) or if this callback must be called once again further (false). If <forceIt> is set to true, the method MUST perform and return true. Does nothing by default and returns true.
 
virtual void BeforeCommitTransaction ()
 A callback. By default does nothing. It is called by TDF_Data::CommitTransaction() method.
 
void Backup ()
 Backups the attribute. The backuped attribute is flagged "Backuped" and not "Valid".
 
Standard_Boolean IsBackuped () const
 Returns true if the attribute backup status is set. This status is set/unset by the Backup() method.
 
virtual Handle< TDF_AttributeBackupCopy () const
 Copies the attribute contents into a new other attribute. It is used by Backup().
 
virtual Handle< TDF_DeltaOnAdditionDeltaOnAddition () const
 Makes an AttributeDelta because <me> appeared. The only known use of a redefinition of this method is to return a null handle (no delta).
 
virtual Handle< TDF_DeltaOnForgetDeltaOnForget () const
 Makes an AttributeDelta because <me> has been forgotten.
 
virtual Handle< TDF_DeltaOnResumeDeltaOnResume () const
 Makes an AttributeDelta because <me> has been resumed.
 
virtual Handle< TDF_DeltaOnModificationDeltaOnModification (const Handle< TDF_Attribute > &anOldAttribute) const
 Makes a DeltaOnModification between <me> and.
 
virtual void DeltaOnModification (const Handle< TDF_DeltaOnModification > &aDelta)
 Applies a DeltaOnModification to <me>.
 
virtual Handle< TDF_DeltaOnRemovalDeltaOnRemoval () const
 Makes a DeltaOnRemoval on <me> because <me> has disappeared from the DS.
 
virtual void References (const Handle< TDF_DataSet > &aDataSet) const
 Adds the first level referenced attributes and labels to <aDataSet>.
 
virtual Standard_OStreamDump (Standard_OStream &anOS) const
 Dumps the minimum information about <me> on <aStream>.
 
Standard_OStreamoperator<< (Standard_OStream &anOS) const
 
virtual void ExtendedDump (Standard_OStream &anOS, const TDF_IDFilter &aFilter, TDF_AttributeIndexedMap &aMap) const
 Dumps the attribute content on <aStream>, using <aMap> like this: if an attribute is not in the map, first put add it to the map and then dump it. Use the map rank instead of dumping each attribute field.
 
void Forget (const Standard_Integer aTransaction)
 Forgets the attribute. <aTransaction> is the current transaction in which the forget is done. A forgotten attribute is also flagged not "Valid".
 
virtual void DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=-1) const
 Dumps the content of me into the stream.
 
- Public Member Functions inherited from Standard_Transient
 Standard_Transient ()
 Empty constructor.
 
 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (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_TransientThis () 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
