Member Typedef Documentation

typedef Handle< StdObjMgt_Persistent >(* StdObjMgt_Persistent::Instantiator) ()

Derived class instance create function.

Member Function Documentation

virtual Handle< TCollection_HAsciiString > StdObjMgt_Persistent::AsciiString ( ) const
virtual

Get referenced ASCII string (to be overriden by ASCII string class; returns a null handle by default for other classes).

Reimplemented in StdLPersistent_HString::Ascii.

virtual Handle< TDF_Attribute > StdObjMgt_Persistent::CreateAttribute ( )
virtual

Create an empty transient attribuite (to be overriden by attribute classes; does nothing and returns a null handle by default for other classes).

Reimplemented in StdLPersistent_Value::UAttribute, and StdLPersistent_TreeNode.

virtual Handle< TCollection_HExtendedString > StdObjMgt_Persistent::ExtString ( ) const
virtual

Get referenced extended string (to be overriden by extended string class; returns a null handle by default for other classes).

Reimplemented in StdLPersistent_HString::Extended.

virtual Handle< TDF_Attribute > StdObjMgt_Persistent::GetAttribute ( ) const
virtual

Get transient attribuite for the persistent data (to be overriden by attribute classes; returns a null handle by default for non-attribute classes).

virtual void StdObjMgt_Persistent::ImportAttribute ( )
virtual

Import transient attribuite from the persistent data (to be overriden by attribute classes; does nothing by default for non-attribute classes).

Reimplemented in StdPersistent_Naming::Naming_1, StdPersistent_Naming::Naming, StdPersistent_DataXtd::Geometry, StdLPersistent_Void::instance< AttribClass >, and StdLPersistent_TreeNode.

virtual void StdObjMgt_Persistent::ImportDocument ( const Handle< TDocStd_Document > &  theDocument) const
virtual
