public class ServerStream<V> implements Iterable<V>A blocking Iterable-style wrapper around server stream responses.
This class asynchronously pulls responses from upstream via StreamController#request(int) and exposes them via its Iterator. The implementation is back pressure aware and uses a constant buffer of 1 item.
Please note that the stream can only be consumed once and must either be fully consumed or be canceled.
Neither this class nor the iterator it returns is thread-safe.
Example usage:

Methods
cancel()
public void cancel()Cleanly cancels a partially consumed stream. The associated iterator will return false for the hasNext() in the next iteration. This maintains the contract that an observed true from hasNext() will yield an item in next(), but afterwards will return false.
isReceiveReady()
public boolean isReceiveReady()Returns true if the next call to the iterator's hasNext() or next() is guaranteed to be nonblocking.
| Type | Description |
| boolean | If the call on any of the iterator's methods is guaranteed to be nonblocking. |
