com.hp.hpl.jena.sparql.engine.binding.BindingMap
Bindings are immutable, and are equal-by-value, but they have to be constructed somehow and this interface captures that. Bindings should be created, then not changed, and returned as type "Binding".

        List<Binding> bindings = new ArrayList<Binding>() ;
        for ( int i = 0 ; i < members.size() ; i++ )
        {
            Node idx = NodeFactory.intToNode(i) ;
            Node member = members.get(i) ;
            BindingMap b = BindingFactory.create(binding) ;
            b.add(varIndex, idx) ;
            b.add(varMember, member) ;
            bindings.add(b) ;
        }
        return new QueryIterPlainWrapper(bindings.iterator(), execCxt) ;
    }
