    Returns:
      The current value

  - ### set

    void set(long value)

    Parameters:
      `value` - The new value

  - ### setValue

    void setValue(Number value)
    Set the wrapped value.

    Note: this method should accept null without throwing an exception, setting "0" instead.

    Specified by:
      `setValue` in interface `WritableValue<Number>`
    Parameters:
      `value` - The new value
