CompositeFuture (Vert.x Stack

All Superinterfaces:

AsyncResult<CompositeFuture>, Future<CompositeFuture>
```
public interface CompositeFuture
extends Future<CompositeFuture>
```
The composite future wraps a list of futures, it is useful when several futures needs to be coordinated. The handlers set for the coordinated futures are overridden by the handler of the composite future.
