const TDF_Label Label () const
 
Returns   the   label to which  the   attribute is <br>
    attached. If the  label is not  included in a  DF, <br>
    the label is null. See Label. <br>

Warning
If the label is not included in a data
framework, it is null.
This function should not be redefined inline.
More...

 
Standard_Integer Transaction () const
 
 Returns the transaction index in which the <br>
     attribute has been created or modified. <br>


More...

 
Standard_Integer UntilTransaction () const

the attribute is/was valid. This number may
vary. A removed attribute validity range is
reduced to its transaction index.
More...

 Returns true if the attribute is valid; i.e. not a <br>
     backuped or removed one. <br>


More...

 
Standard_Boolean IsNew () const
 
 Returns true if the attribute has no backup <br>

of <me> with <anID> as ID.
More...
 
Standard_Boolean FindAttribute (const Standard_GUID &anID, Handle< TDF_Attribute > &anAttribute) const
 
 Finds an associated  attribute of  <me>, according <br>
     to <anID>.  the returned <anAttribute> is a  valid <br>
     one. The  method  returns  True if   found,  False <br>
     otherwise.   A removed attribute  cannot be found using <br>

this method.
More...

 
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>.
More...
 
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.
More...
 
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
More...
 
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.
More...
 
virtual void BeforeCommitTransaction ()
 A callback.
By default does nothing.
It is called by TDF_Data::CommitTransaction() method.
More...
 
void Backup ()
 
 Backups the attribute. The backuped attribute is <br>
     flagged "Backuped" and not "Valid". <br>


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.
More...

 
Standard_Boolean IsBackuped () const
 
 Returns true if the attribute backup status is <br>
     set. This status is set/unset by the <br>
     Backup() method. <br>


More...

 
virtual 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).
More...
 
virtual Handle_TDF_DeltaOnForget DeltaOnForget () const
 Makes an AttributeDelta because <me> has been
forgotten.
More...
 
virtual Handle_TDF_DeltaOnResume DeltaOnResume () const
 Makes an AttributeDelta because <me> has been
resumed.
More...
 
virtual
Handle_TDF_DeltaOnModification 
DeltaOnModification (const Handle< TDF_Attribute > &anOldAttribute) const
 Makes a DeltaOnModification between <me> and
<anOldAttribute.
More...
 
virtual void DeltaOnModification (const Handle< TDF_DeltaOnModification > &aDelta)
 Applies a DeltaOnModification to <me>.
More...
 
virtual Handle_TDF_DeltaOnRemoval DeltaOnRemoval () const
 Makes a DeltaOnRemoval on <me> because <me> has
disappeared from the DS.
More...
 
virtual void References (const Handle< TDF_DataSet > &aDataSet) const
 
 Adds the first level referenced attributes and labels <br>
     to <aDataSet>. <br>


For this, use the AddLabel or AddAttribute of
DataSet.

If there is none, do not implement the method.
More...

 
virtual Standard_OStreamDump (Standard_OStream &anOS) const
 
 Dumps the minimum information about <me> on <br>
     <aStream>. <br>


More...

 
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.
More...
 
void Forget (const Standard_Integer aTransaction)
 
 Forgets the attribute. <aTransaction> is the <br>
     current transaction in which the forget is done. A <br>
     forgotten attribute is also flagged not "Valid". <br>


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.
