  • Method Details

    • get

      Object get(Object instance)
      Gets the current value of the field. If the field is a primitive value, then the primitive will be wrapped.
      Throws:
      NullPointerException - if the instance is null
      ClassCastException - if the instance is not the type that contains the field
    • set

      void set(Object instance, Object newValue)
      Updates the current value of the field. If the field is a primitive value, then the newValue will be unwrapped automatically.
      Throws:
      NullPointerException - if the instance is null
      NullPointerException - if the newValue is null and the field is a primitive type
      ClassCastException - if the instance is not the type that contains the field
      ClassCastException - if the newValue is not assignable to the field type (or not the matching wrapper type for a primitive field)
