Examples of BindingMap

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".

        if ( ! node.isURI() ) return ;
        Node localname = Node.createLiteral(node.getLocalName()) ;
        if ( nodeLocalname.isVariable() )
        {
            // Object is an unbound variable.
            Binding b = new BindingMap(input) ;
            // Bind a pair for subject and object variables
            b.add(Var.alloc(subjVar), node) ;
            b.add(Var.alloc(nodeLocalname), localname) ;
            bindings.add(b) ;
            return ;
        }
        
        // Object is a value / bound variable.
