 Restores the backuped contents from <anAttribute> into this one. It is used when aborting a transaction.
 
Handle< TDF_AttributeNewEmpty () const override
 Returns an new empty attribute from the good end type. It is used by the copy algorithm.
 
void Paste (const Handle< TDF_Attribute > &Into, const Handle< TDF_RelocationTable > &RT) const override
 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>.
 
virtual Standard_OStreamDump (Standard_OStream &anOS) const override
 Dumps the minimum information about <me> on <aStream>.

- Public Member Functions inherited from TDF_Attribute
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 void AfterAddition ()
 Something to do after adding an Attribute to a label.
 
virtual void BeforeRemoval ()
 Something to do before removing an Attribute from a label.
 
virtual void BeforeForget ()

virtual void AfterResume ()
 Something to do after resuming an Attribute from a label.
 
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 Standard_Boolean BeforeUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False)
 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.
 
virtual Standard_Boolean AfterUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False)
 Something to do after 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.
 
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

virtual Handle< TDF_DeltaOnResumeDeltaOnResume () const
 Makes an AttributeDelta because <me> has been resumed.

virtual void References (const Handle< TDF_DataSet > &aDataSet) const
 Adds the first level referenced attributes and labels to <aDataSet>.
 
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".
