Function deferOrCancel

  • deferOrCancel(delay: number, callback?: ConvertFunction): Transformer

  • Builds function which delays the synchronization for given msec and cancels the execution if transformer is triggered again. In contrast to debounceOrCancel this method ensures that after the given delay at least one update is performed.

    Parameters

    • delay: number

      time in msec to wait before synchronizing.

    • Optionalcallback: ConvertFunction

      callback which transforms the value.

    Returns Transformer

    transformer function.

    Example

    let a = new Clazz({prop: 2});
    let b = new Clazz();
    Binding.for(a, b)
       .syncToRight("prop",
           deferOrCancel(100)
        ).enable().syncToRightNow();
    b.prop // is undefined but will be set after 100msec to 2
