Examples of com.sleepycat.je.utilint.TinyHashSet

com.sleepycat.je.utilint.TinyHashSet
TinyHashSet is used to optimize (for speed, not space) the case where a HashSet generally holds a single element. This saves us the cost of creating the HashSet and related elements as well as call Object.hashCode(). If single != null, it's the only element in the TinyHashSet. If set != null then there are multiple elements in the TinyHashSet. It should never be true that (single != null) && (set != null).

        final TinyHashSet<ThreadLocker> set = threadLockers.get(thread);
        if (set != null) {
            final boolean added = set.add(locker);
            assert added;
        } else {
            threadLockers.put(thread, new TinyHashSet(locker));
        }
    }
