question: public void attributeAsClass ( ) { DataSortedTableModel model ; if ( m_CurrentCol == - 1 ) { return ; } model = ( DataSortedTableModel ) m_TableData . getModel ( ) ; if ( model . getAttributeAt ( m_CurrentCol ) == null ) { return ; } setCursor ( Cursor . getPredefinedCursor ( Cursor . WAIT_CURSOR ) ) ; model . attributeAsClassAt ( m_CurrentCol ) ; setCursor ( Cursor . getPredefinedCursor ( Cursor . DEFAULT_CURSOR ) ) ; }
target:  sets the current attribute as class attribute, i.e. it moves it to the end of the attributes
