      • drainToAsync

        public RFuture<Integer> drainToAsync(Collection<? super V> c)
        Description copied from interface: RBlockingQueueAsync
        Removes all available elements from this queue and adds them to the given collection in async mode. This operation may be more efficient than repeatedly polling this queue. A failure encountered while attempting to add elements to collection c may result in elements being in neither, either or both collections when the associated exception is thrown. Attempts to drain a queue to itself result in IllegalArgumentException. Further, the behavior of this operation is undefined if the specified collection is modified while the operation is in progress.
        Specified by:
        drainToAsync in interface RBlockingQueueAsync<V>
        Parameters:
        c - the collection to transfer elements into
        Returns:
        the number of elements transferred
      • drainToAsync

        Description copied from interface: RBlockingQueueAsync
        Removes at most the given number of available elements from this queue and adds them to the given collection in async mode. A failure encountered while attempting to add elements to collection c may result in elements being in neither, either or both collections when the associated exception is thrown. Attempts to drain a queue to itself result in IllegalArgumentException. Further, the behavior of this operation is undefined if the specified collection is modified while the operation is in progress.
        Specified by:

        Parameters:
        c - the collection to transfer elements into
        maxElements - the maximum number of elements to transfer
        Returns:
        the number of elements transferred
