// A warden that knows how to register lists with a listmanager and keep them

|

// inherit from it.
|

|
|
// Classes that inherit from ListWarden are responsible for calling
|
|
// enableTableUpdates or disableTableUpdates. This usually entails
|
|
// registering prefObservers and calling enable or disable in the base
|
|
// class as appropriate.
