CompositeIoFuture

java.lang.Object
- org.apache.mina.core.future.DefaultIoFuture
- - org.apache.mina.core.future.CompositeIoFuture<E>

Type Parameters:

E - the type of the child futures.

All Implemented Interfaces:

IoFuture
```
public class CompositeIoFuture<E extends IoFuture>
extends DefaultIoFuture
```
An IoFuture of IoFutures. It is useful when you want to get notified when all IoFutures are complete. It is not recommended to use CompositeIoFuture if you just want to wait for all futures. In that case, please use IoUtil.await(Iterable) instead for better performance.
