Method Detail

futuresCombiner
```
public static FuturesCombiner futuresCombiner(ExecutorService executorService)
```
Constructs a FuturesCombiner implementation which takes ownership of the executorService and calls ExecutorService.shutdown() when close is called on it.

Parameters:

executorService - to be used to combine the futures

Returns:

implementation of FuturesCombiner

allOptionalsAsMap

public static <T,R> com.google.common.util.concurrent.ListenableFuture<Map<T,R>> allOptionalsAsMap(Map<T,com.google.common.util.concurrent.ListenableFuture<Optional<R>>> inputToListenableFutureMap,
                                                                                                               Executor executor)

Creates a new ListenableFuture whose value is a map containing the values of all its input futures, if all succeed. Input key-value pairs for which the input futures resolve to Optional.empty() are filtered out.

Type Parameters:: T - type of query input; R - type of query result
Parameters:: inputToListenableFutureMap - query input to ListenableFuture of the query result
Returns:: ListenableFuture of the combined map
