    - #### isInvariant

          public boolean isInvariant()

      Returns true.

          public java.lang.Class getBindingType()

      Description copied from class: `AbstractBinding`
      Returns the actual class, by invoking `Binding.get()`. Subclasses may override this method to work more efficiently (say, when the binding type is known statically).
      Specified by:
        `getBindingType` in interface `Binding`
      Overrides:
        `getBindingType` in class `AbstractBinding`

    - #### toString
