Examples of net.tomp2p.peers.Number160

net.tomp2p.peers.Number160
This class represents a 160 bit number. This class is preferred over BigInteger as we always have 160bit, and thus, methods can be optimized. @author Thomas Bocek


        Number160[] number160s = new Number160[nr];
        AtomicReferenceArray<FutureTest> array = new AtomicReferenceArray<FutureTest>(new FutureTest[nr]);
        Random rnd = new Random(1);
        for (int i = 0; i < nr; i++) {
            number160s[i] = new Number160(rnd);
        }
        long start = System.currentTimeMillis();
        recursive(array, number160s, 0, RONUDS / SUB, 0);
