Abstract Value Members

  1. abstract def !(op: (SafeJsValue) ⇒ SafeJsValue): Update

  2. abstract def updated(f: (SafeJsValue) ⇒ SafeJsValue)(parent: JsValue): SafeJsValue

    Applies function f on the child of the parent denoted by this UpdateLens and returns a Right of the parent with the child element updated.

    Applies function f on the child of the parent denoted by this UpdateLens and returns a Right of the parent with the child element updated.

    The value passed to f may be Left(e) if the child could not be found in which case particular operations may still succeed. Function f may return Left(error) in case the operation fails.

    updated returns Left(error) if the update operation or any of any intermediate lens fails.
