    Get the thread-specific Location for this Location.

  • get

    public T get()

    Description copied from class: Location
    Get the current value of this location.

    Specified by:

    get in class Location<T>

  • get

    public T get(T defaultValue)

    Overrides:

    get in class Location<T>

  • isBound

    public boolean isBound()

    Specified by:

    isBound in class Location<T>

  • set

    public void set(T value)

    Specified by:

    set in class Location<T>

  • setWithSave

    public java.lang.Object setWithSave(T newValue)

    Description copied from class: Location
    Set a value, but return cookie so old value can be restored. This is intended for fluid-let where (in the case of multiple threads) a simple save-restore isn't always the right thing.

    Description copied from class: Location
    Restore an old value.

    Overrides:
