CountDown (Digipost Digg 0.33 API)

java.lang.Object
- no.digipost.concurrent.CountDown

All Implemented Interfaces:

TargetState
```
public final class CountDown
extends Object
implements TargetState
```
A count down implementation of TargetState, which will count the invocations of yet() and return true after a given amount of invocations.
The implementation is thread-safe in the sense that it is guaranteed that yet() will return false an exact amount of times, regardless of different threads invoking yet(), before switching to only return true.
This can often serve for testing purposes where you would like a controlled amount of queries to a TargetState, before it changes.
