    • Method Detail

      • setMaxResultCount

        public void setMaxResultCount​(int max)
        Unsupported for subscriptions.
        Overrides:
        setMaxResultCount in class IntermediateFuture<E>
        Parameters:
        max - The maximum number of results.
      • storeResult

        protected void storeResult​(E result,
                                   boolean scheduled)
        Add a result.
        Overrides:
        storeResult in class IntermediateFuture<E>
        Parameters:
        result - The result.
        scheduled - True, if any listener notification has been scheduled for this result. (used for subscription futures to check for lost values)
      • getResultCount

        protected int getResultCount()
        Get the number of results already collected.
        Overrides:
        getResultCount in class IntermediateFuture<E>
        Returns:
        The number of results.
      • addQuietListener

        public void addQuietListener​(IResultListener<java.util.Collection<E>> listener)
        Add a listener which is only informed about new results, i.e. the initial results are not posted to this listener, even if it is the first listener to be added to this future.
        Specified by:
        addQuietListener in interface ISubscriptionIntermediateFuture<E>
      • getNextIntermediateResult

        public E getNextIntermediateResult​(long timeout,
                                           boolean realtime)
        Iterate over the intermediate results in a blocking fashion. Manages results independently for different callers, i.e. when called from different threads, each thread receives all intermediate results. The operation is guaranteed to be non-blocking, if hasNextIntermediateResult() has returned true before for the same caller. Otherwise the caller is blocked until a result is available or the future is finished.
        Specified by:
        getNextIntermediateResult in interface IIntermediateFuture<E>
        Overrides:
        getNextIntermediateResult in class IntermediateFuture<E>
        Parameters:
        timeout - The timeout in millis.
        realtime - Flag, if wait should be realtime (in constrast to simulation time).
        Returns:
        The next intermediate result.
      • hasNextIntermediateResult

        public boolean hasNextIntermediateResult​(long timeout,
                                                 boolean realtime)
        Check if there are more results for iteration for the given caller. If there are currently no unprocessed results and future is not yet finished, the caller is blocked until either new results are available and true is returned or the future is finished, thus returning false.
        Specified by:
        hasNextIntermediateResult in interface IIntermediateFuture<E>
        Overrides:
        hasNextIntermediateResult in class IntermediateFuture<E>
        Parameters:
        timeout - The timeout in millis.
        realtime - Flag, if wait should be realtime (in constrast to simulation time).
        Returns:
        True, when there are more intermediate results for the caller.
      • doGetNextIntermediateResult

        protected E doGetNextIntermediateResult​(int index,
                                                long timeout,
                                                boolean realtime)
        Perform the get without increasing the index.
        Overrides:
        doGetNextIntermediateResult in class IntermediateFuture<E>
