/** A simple interface between persistent and temporary storage.
|
|
* This class is used simply for transmitting information about
|
|
* connections.
|
|
* <p>
|
|
* The speciality of this class is that the operations need not make
|
|
* sense atomically: only the end result of several operations counts.
|
|
* So if a is connected to b, then connect(b, -, c), disconnect(a, +),
|
|
* is perfectly valid.
|
|
* All disconnections must be given in both directions; connects
|
|
* only once (that's why there's no dir there).
|
|
* <p>
|
|
* If the above seems unclear, just see how it's used and where
|
|
* it's not used: the class that is used for the on-line dims is ZZDimension.
