Examples of BindingSet

edu.umd.cs.findbugs.ba.bcp.BindingSet
A set of Bindings, which are definitions of variables occuring in a ByteCodePattern. BindingSets are immutable; to add a binding, a new cell is allocated. (Are we CONSING yet?) @author David Hovemeyer @see Binding
org.openrdf.query.BindingSet
A BindingSet is a set of named value bindings, which is used a.o. to represent a single query solution. Values are indexed by name of the binding which typically corresponds to the names of the variables used in the projection of the orginal query.

    try {

      assertTrue(result.hasNext());


      while (result.hasNext()) {
        BindingSet solution = result.next();

        assertTrue(solution.hasBinding("mbox"));


        Value nameResult = solution.getValue("name");
        Value mboxResult = solution.getValue("mbox");
