    • update

      void update(T target, U value)
      Update the state of the passed target object using the passed value. For intrinsic types, the specified value is expected to be a standard wrapper type in the same manner that reflection works; for example, an int value would be passed as a java.lang.Integer.
      Parameters:
      target - the Object to update the state of
      value - the new value to update the state with
      Throws:
      ClassCastException - if this ValueUpdater is incompatible with the passed target object or the value and the implementation requires the passed object or the value to be of a certain type
      WrapperException - if this ValueUpdater encounters a checked exception in the course of updating the target object
      IllegalArgumentException - if this ValueUpdater cannot handle the passed target object or value for any other reason; an implementor should include a descriptive message
