Interface Reference<T>


  • public interface Reference<T>
    A very general purpose interface to provide a reference to an object that may or may not be available. Uses can range from allowing someone else to attach/detach the value, to calculating the reference on the fly.

    Does not support null values, as null represents "not available". If you need to pass null, you should use a sentinel that extends from T to indicate the null condition.
