      • isDone

        public boolean isDone()
        Description copied from interface: PromisedValues
        The true if the all the futures have completed (and hence this PromisedValues has completed)
        Specified by:
        isDone in interface PromisedValues<T>
        Returns:
        true if all the futures have completed

      • cause

        public java.lang.Throwable cause()
        Description copied from interface: PromisedValues
        The exception cause or null if it didn't fail
        Specified by:
        cause in interface PromisedValues<T>
        Returns:
        an exception or null if the future did not fail

      • succeeded

        public boolean succeeded​(int index)
        Description copied from interface: PromisedValues
        The true if the CompletionStage at the specified index succeeded
        Specified by:
        succeeded in interface PromisedValues<T>
        Parameters:
        index - the index of the CompletionStage
        Returns:
        true if the future at the specified index succeeded

      • cause

        public java.lang.Throwable cause​(int index)
        Description copied from interface: PromisedValues
        The exception cause at the specified index or null if it didn't fail
        Specified by:
        cause in interface PromisedValues<T>
        Parameters:
        index - the index of the CompletionStage
        Returns:
        an exception or null if the future did not fail

      • get

        public T get​(int index)
        Description copied from interface: PromisedValues
        The value at index or null if it failed
        Specified by:
        get in interface PromisedValues<T>
        Parameters:
        index - the index of the future
        Returns:
        the value of the future

      • toList

        public java.util.List<T> toList()
        Description copied from interface: PromisedValues
        Returns the underlying values as a list
        Specified by:
        toList in interface PromisedValues<T>
        Returns:
        the list of underlying values

      • size

        public int size()
        Specified by:
        size in interface PromisedValues<T>
        Returns:

      • join

        public java.util.List<T> join()
        Description copied from interface: PromisedValues
        Waits for the underlying futures to complete. To better conform with the use of common functional forms, if a computation involved in the completion of this CompletableFuture threw an exception, this method throws an (unchecked) CompletionException with the underlying exception as its cause.
        Specified by:
        join in interface PromisedValues<T>
        Returns:
        the list of completed values similar to PromisedValues.toList()
