ThreadRobustList (vespajlib 7.522.16 API)

java.lang.Object
- com.yahoo.concurrent.ThreadRobustList<T>

All Implemented Interfaces:

Iterable<T>
```
public class ThreadRobustList<T>
extends Object
implements Iterable<T>
```
A list which tolerates concurrent adds from one other thread while it is read. More precisely: This list is guaranteed to provide a self-consistent read view regardless of the internal order in which the primitive mutating operations on it are observed from the reading thread.
This is useful for traced information as there may be timed out threads working on the structure after it is returned upwards for consumption.
