  • Constructor Details

    • ArrayBindingSet

      public ArrayBindingSet(String... names)
      Creates a new Array-based BindingSet for the supplied bindings names. The supplied list of binding names is assumed to be constant; care should be taken that the contents of this array doesn't change after supplying it to this solution.
      Parameters:
      names - The binding names.

      public ArrayBindingSet(BindingSet toCopy, Set<String> names, String[] namesArray)

    • getDirectSetBinding

      public BiConsumer<Value,ArrayBindingSet> getDirectSetBinding(String bindingName)
      This is used to generate a direct setter into the array to put a binding value into. Can be used to avoid many comparisons to the bindingNames.
      Parameters:
      bindingName - for which you want the setter
      Returns:
      the setter biconsumer which can operate on any ArrayBindingSet but should only be used on ones with an identical bindingNames array. Otherwise returns null.

      public Set<String> getBindingNames()
      Description copied from interface: BindingSet
      Gets the names of the bindings in this BindingSet.

      Returns:
      A set of binding names.

      public Value getValue(String bindingName)
      Description copied from interface: BindingSet
      Gets the value of the binding with the specified name from this BindingSet.
      Specified by:
      getValue in interface BindingSet
      Parameters:
      bindingName - The name of the binding.
      Returns:
      The value of the binding with the specified name, or null if there is no such binding in this BindingSet.
    • getBinding

      The binding with the specified name, or null if there is no such binding in this BindingSet.
    • hasBinding

      public boolean hasBinding(String bindingName)
      Description copied from interface: BindingSet
      Checks whether this BindingSet has a binding with the specified name.

      Parameters:
      bindingName - The name of the binding.
      Returns:
