@Override
public void delete(Triple t) throws DeleteDeniedException
{
  graph.delete(t) ;
}

/**
  Remove a triple from the difference: remove it from the left operand. [It could
  be added to the right operand instead, but somehow that feels less satisfactory.]
*/
@Override public void performDelete( Triple t )
  { L.delete( t ); }

  right operand.
