  • Constructor Details

    • 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.

    • ListBindingSet

      public ListBindingSet​(List<String> bindingNames, List<? extends Value> values)

The supplied lists are assumed to be constant; care should be taken that the contents of these lists don't change after supplying them to this solution. The number of supplied values must be equal to the number of the binding names.
      Parameters:
      bindingNames - The binding names.
      values - The binding values.
