 Copies the attribute contents into a new other attribute. It is used by Backup().
 
virtual void Restore (const Handle< TDF_Attribute > &anAttribute) override
 Restores the contents from <anAttribute> into this one. It is used when aborting a transaction.
 
virtual Handle< TDF_DeltaOnModificationDeltaOnModification (const Handle< TDF_Attribute > &anOldAttribute) const override
 Makes a DeltaOnModification between <me> and.
 
virtual void DeltaOnModification (const Handle< TDF_DeltaOnModification > &aDelta) override

virtual Handle< TDF_DeltaOnRemovalDeltaOnRemoval () const override
 Makes a DeltaOnRemoval on <me> because <me> has disappeared from the DS.
 
virtual Handle< TDF_AttributeNewEmpty () const override
 Returns an new empty attribute from the good end type. It is used by the copy algorithm.
 
virtual void Paste (const Handle< TDF_Attribute > &intoAttribute, const Handle< TDF_RelocationTable > &aRelocTationable) 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 pastes the current attribute to the label corresponding to the insertor. The pasted attribute may be a brand new one or a new version of the previous one.
 
virtual void References (const Handle< TDF_DataSet > &aDataSet) const override
 Adds the directly referenced attributes and labels to <aDataSet>. "Directly" means we have only to look at the first level of references.
 
virtual void BeforeRemoval () override
 Something to do before removing an Attribute from a label.
 
virtual Standard_Boolean BeforeUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False) override
 Something to do before applying <anAttDelta>
 
virtual Standard_Boolean AfterUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False) override

 Dumps the content of me into the stream.
 
- 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

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 BeforeForget ()
 Something to do before forgetting an Attribute to a label.
 
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 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_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.
 
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".

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.

 Get the reference counter of this object.

 Increments the reference counter of this object.

Detailed Description

The basis to define an attribute for the storage of topology and naming data. This attribute contains two parts:

  • The type of evolution, a term of the enumeration TNaming_Evolution
  • A list of pairs of shapes called the "old" shape and the "new" shape. The meaning depends on the type of evolution.
