    • ListBindingSet

      public ListBindingSet(List<String> names, Value... values)
      Creates a new List-based BindingSet containing the supplied bindings. The supplied list of binding names is assumed to be constant; care should be taken that the contents of this list doesn't change after supplying it to this solution. The number of supplied values must be equal to the number of the binding names.
      Parameters:
      names - The binding names.
      values - The binding values.
