"
    I describe a breakpoint: its state (enabled/disabled),
    condition, etc.

    I may be shared by multiple instances of Breakpoint,
    since there may be multiple version of same method
    with breakpoints on different position but representing
    the same logical breakpoint (the one use entered).
