Where is DoubleStream? about lightweight-stream-api

[aNNiMON]

@PromanSEW currently LongStream and DoubleStream are not implemented. Use Stream<Long> and Stream<Double> instead.

It is easy to add it yourself and make the addition and do a pull request. Please ad LongStream and if You can BoolStream, CharStream and ShortShortStream.
I forked the lib for other reasons after I was halfway my own implementation.

[nicenemo]

that means boxing.

[PromanSEW]

@nicenemo you are right, so I create this issue. Array of array of double (double[][]) is not supported by flatMap, after second applying it is still double[], and doesn't flatten to Stream of double. Stream<Double> is not applicable for non-boxed array

[aNNiMON]

@PromanSEW, you can use this simple workaround until I implement DoubleStream:

double[][] input = {{1.0, 2.0}, {3.0, 4.0}, {5.0, 6.0}};
Stream.of(input)
        .flatMap(arr -> IntStream.range(0, arr.length).mapToObj(i -> arr[i]))
        .forEach(System.out::println);

@aNNiMON thanks for this solution. Still watching for development of this useful library
