- Method Detail
  - add
```
void add(@NotNull
         IMessage message)
```
  - clear
```
void clear()
```
  - wake
```
void wake()
```
    Request to bring this list to user's attention. Could show a balloon, bring a view to front, blink window header, or do nothing at all, solely at implementation discretion. There's no limit on which thread may initiate this wake-up, however, it is expected to reflect state of the list prior to the call, e.g. with a sequence add(m1); add(m2); add(m3); wake(); it's reasonable to expect wake would bring all three messages visible.
