- Public Member Functions inherited from TDF_Attribute
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. More...
 
Standard_Integer Transaction () const
 Returns the transaction index in which the attribute has been created or modified. More...
 
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. More...
 
Standard_Boolean IsValid () const
 Returns true if the attribute is valid; i.e. not a backuped or removed one. More...
 
Standard_Boolean IsNew () const
 Returns true if the attribute has no backup. More...
 
Standard_Boolean IsForgotten () const
 Returns true if the attribute forgotten status is set. More...
 
Standard_Boolean IsAttribute (const Standard_GUID &anID) const
 Returns true if it exists an associated attribute 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 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. More...

 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 current transaction in which the forget is done. A forgotten attribute is also flagged not "Valid". More...

Detailed Description

Purpose: OCAF Attribute to storing objects (interfaces) of OCAF-based modelers in the OCAF tree. The persistency mechanism of the TObj_TObject allowes to save and restore objects of various subtypes without recompilation of the schema
