# TDF_Attribute Class Reference

This abstract class, alongwith Label,
is one of the cornerstones of Model Editor.
The groundwork is to define the root of
information. This information is to be
attached to a Label, and could be of any of
the following types:
- a feature
- a constraint
- a comment
Contents:
---------
Each software component who'd like to attach its
own information to a label has to inherit from
this class and has to add its own information as
fields of this new class.
Identification:
---------------
An attribute can be identified by its ID. Every
attributes used with the same meaning (for
exemple: Integer, String, Topology...) have the
same worldwide unique ID.
Addition:
---------
An attribute can be added to a label only if there
is no attribute yet with the same ID. Call-back
methods are offered, called automatically before
and after the addition action.
Removal:
--------
An attribute can be removed from a label only if
there is an attribute yet with the same
ID. Call-back methods are offered, called
automatically before and after the removal
action. A removed attribute cannot be found
again. After a removal, only an addition of an
attribute with the sane ID is possible (no
backup...).
Modification & Transaction:
---------------------------
An attribute can be backuped before a
modification. Only one backup attribute by
transaction is possible. The modification can be
forgotten (abort transaction) or validated (commit
transaction).
BackupCopy and restore are methods used by the backup or
abort transaction actions. BackupCopy is called by
Backup to generate an attribute with the same
contents as the current one. Restore is called
when aborting a transaction to transfer the
backuped contents into the current
attribute. These methods must be implemented by
end use inheriting classes.
A standard implementation of BackupCopy is provided, but
it is not necessary a good one for any use.
Copy use methods:
-----------------
Paste and NewEmpty methods are used by the copy
algorithms. The goal of "Paste" is to transfer an
attribute new contents into another attribute. The
goal of "NewEmpty" is to create an attribute
whithout contents, to be further filled with the
new contents of another one. These 2 methods must
be implemented by end use inheriting classes.
AttributeDelta:
---------------
An AttributeDelta is the difference between to
attribute values states. These methods must be
implemented by end use inheriting classes, to
profit from the delta services.

## Public Member Functions

virtual Standard_EXPORT const Standard_GUID & | ID () const =0
| Returns the ID of the attribute. .
Standard_EXPORT 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_EXPORT 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. //! ShortCut Methods concerning associated attributes ================================================= .
Standard_EXPORT Standard_Boolean | IsAttribute (const Standard_GUID &anID) const
| Returns true if it exists an associated attribute of <me> with <anid> as ID. .
Standard_EXPORT 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. .
Standard_EXPORT 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_EXPORT Standard_Boolean | ForgetAttribute (const Standard_GUID &aguid) const
| Forgets the Attribute of GUID <aguid> associated to the label of <me>. Be carefull 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. .
Standard_EXPORT 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 mecanisms. Be carefull that if <me> will have a null label after this call .
virtual Standard_EXPORT void | AfterAddition ()
| Something to do after adding an Attribute to a label. .
virtual Standard_EXPORT void | BeforeRemoval ()
| Something to do before removing an Attribute from a label. .
virtual Standard_EXPORT void | BeforeForget ()
| Something to do before forgetting an Attribute to a label. .
virtual Standard_EXPORT void | AfterResume ()
| Something to do after resuming an Attribute from a label. .
virtual Standard_EXPORT 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_EXPORT 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_EXPORT 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 Standard_EXPORT void | BeforeCommitTransaction ()
| A callback. By default does nothing. It is called by TDF_Data::CommitTransaction() method. .
Standard_EXPORT void | Backup ()
| Backups the attribute. The backuped attribute is flagged "Backuped" and not "Valid". The method does nothing: 1) If the attribute transaction number is equal to the current transaction number (the attribute has already been backuped). 2) If the attribute is not attached to a label. .
Standard_Boolean | IsBackuped () const
| Returns true if the attribute backup status is set. This status is set/unset by the Backup() method. .
virtual Standard_EXPORT Handle_TDF_Attribute | BackupCopy () const
| Copies the attribute contents into a new other attribute. It is used by Backup(). .
virtual Standard_EXPORT void | Restore (const Handle(TDF_Attribute)&anAttribute)=0
| Restores the backuped contents from <anattribute> into this one. It is used when aborting a transaction. .
virtual Standard_EXPORT Handle_TDF_DeltaOnAddition | DeltaOnAddition () 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 Standard_EXPORT Handle_TDF_DeltaOnForget | DeltaOnForget () const
| Makes an AttributeDelta because <me> has been forgotten. .
virtual Standard_EXPORT Handle_TDF_DeltaOnResume | DeltaOnResume () const
| Makes an AttributeDelta because <me> has been resumed. .
virtual Standard_EXPORT Handle_TDF_DeltaOnModification | DeltaOnModification (const Handle(TDF_Attribute)&anOldAttribute) const
| Makes a DeltaOnModification between <me> and <anOldAttribute. .
virtual Standard_EXPORT void | DeltaOnModification (const Handle(TDF_DeltaOnModification)&aDelta)
| Applies a DeltaOnModification to <me>. .
virtual Standard_EXPORT Handle_TDF_DeltaOnRemoval | DeltaOnRemoval () const
| Makes a DeltaOnRemoval on <me> because <me> has disappeared from the DS. .
virtual Standard_EXPORT Handle_TDF_Attribute | NewEmpty () const =0
| Returns an new empty attribute from the good end type. It is used by the copy algorithm. .
virtual Standard_EXPORT void | Paste (const Handle(TDF_Attribute)&intoAttribute, const Handle(TDF_RelocationTable)&aRelocationTable) const =0

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 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_OStream & | operator<< (Standard_OStream &anOS) const
virtual Standard_EXPORT 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. .
Standard_EXPORT 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".
A forgotten attribute is invisible. Set also the
"Valid" status to False. Obvioulsy, DF cannot
empty an attribute (this has a semantic
signification), but can remove it from the
structure. So, a forgotten attribute is NOT an empty
one, but a soon DEAD one.
Should be private.
