Method Detail

### listenInPoolThread

    public static <V> ListenableFuture<V> listenInPoolThread(Future<V> future)

  Assigns a thread to the given `Future` to provide `ListenableFuture` functionality.

  Warning: If the input future does not already implement `ListenableFuture`, the returned future will emulate `ListenableFuture.addListener(java.lang.Runnable, java.util.concurrent.Executor)` by taking a thread from an internal, unbounded pool at the first call to `addListener` and holding it until the future is done.

  Prefer to create `ListenableFuture` instances with `SettableFuture`, `MoreExecutors.listeningDecorator( java.util.concurrent.ExecutorService)`, `ListenableFutureTask`, `AbstractFuture`, and other utilities over creating plain `Future` instances to be upgraded to `ListenableFuture` after the fact.
