const Standard_GUID &	ID () const override
	Returns the ID of the attribute.

void	Restore (const Handle< TDF_Attribute > &With) override
	Restores the backuped contents from <anAttribute> into this one. It is used when aborting a transaction.

Handle< TDF_Attribute >	NewEmpty () 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_OStream &	Dump (Standard_OStream &anOS) const override
	Dumps the minimum information about <me> on <aStream>.

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 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 ()
	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 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_Attribute >	BackupCopy () const
	Copies the attribute contents into a new other attribute. It is used by Backup().

virtual Handle< TDF_DeltaOnAddition >	DeltaOnAddition () const

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

	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>.

Standard_OStream &	operator<< (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_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.

overridevirtual

Returns the ID of the attribute.

Implements TDF_Attribute.

◆ NewEmpty()

Handle< TDF_Attribute > TDocStd_Owner::NewEmpty ( ) const

overridevirtual

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

It is possible to use <aRelocationTable> to get/set the relocation value of a source attribute.

Implements TDF_Attribute.

◆ Restore()

void TDocStd_Owner::Restore ( const Handle< TDF_Attribute > & anAttribute )

overridevirtual

Restores the backuped contents from <anAttribute> into this one. It is used when aborting a transaction.

Implements TDF_Attribute.
