-- Stored as Attribute of The Root.

---Purpose: Returns the ID of the attribute.

GetID(myclass) returns GUID from Standard;
---Purpose: Returns the ID: 2a96b614-ec8b-11d0-bee7-080009dc3333.

BackupCopy(me) returns mutable Attribute from TDF
is redefined;
---Purpose: Copies the attribute contents into a new other
-- attribute. It is used by Backup().
Restore(me: mutable; anAttribute : Attribute from TDF)
is redefined;
---Purpose: Restores the contents from <anAttribute> into this
-- one. It is used when aborting a transaction.
BeforeRemoval(me: mutable)
is redefined;
---Purpose: Clears the table.
AfterUndo(me: mutable;
anAttDelta : AttributeDelta from TDF;
forceIt : Boolean from Standard = Standard_False)
returns Boolean from Standard
is redefined;
---Purpose: Something to do after applying <anAttDelta>.
---Category: Delta generation
-- =================================================
DeltaOnAddition(me)
returns DeltaOnAddition from TDF is redefined;
---Purpose : this method returns a null handle (no delta).
DeltaOnRemoval(me)
returns DeltaOnRemoval from TDF is redefined;
---Purpose : this method returns a null handle (no delta).
-- Copy use methods
-- ----------------
NewEmpty(me)
returns mutable Attribute from TDF
is redefined;
---Purpose: Returns an new empty attribute from the good end
-- type. It is used by the copy algorithm.
Paste(me;
intoAttribute : mutable Attribute from TDF;
aRelocTationable : mutable RelocationTable from TDF)
is redefined;
---Purpose: 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.
References(me; aDataSet : DataSet from TDF)
is redefined;
---Purpose: Adds the directly referenced attributes and labels
-- to <aDataSet>. "Directly" means we have only to
-- look at the first level of references.
--
-- For this, use only the AddLabel() & AddAttribute()
-- from DataSet and do not try to modify information
-- previously stored in <aDataSet>.
-- Miscelleaneous
-- --------------
Dump(me; anOS : in out OStream from Standard)
returns OStream from Standard
is redefined ;
---Purpose: Dumps the attribute on <aStream>.
