如何从ConcurrentHashMap<String,Set<String>>中删除用作值的集合?

ConcurrentHashMap<String, Set<String>> map = new ConcurrentHashMap<>();

// Add element: {mapKey, setValue}

map.computeIfAbsent(mapKey, new Function<String, Set<String>>() {
    @Override
    public Set<String> apply(String mapK) {
        return ConcurrentHashMap.newKeySet();
    }
}).add(setValue);

// Remove element: {mapKey, setValue}

Set<String> updatedSet = map.computeIfPresent(mapKey, new BiFunction<String, Set<String>, Set<String>>() {
    @Override
    public Set<String> apply(String mapK, Set<String> old) {
        old.remove(setValue);
        return old;
    }
});

// I need remove mapKey, but I cannod do this like this, because of race condition bug
if (updatedSet.isEmpty()) {
    map.remove(mapKey);
}

因此,我们可以看到:

1. 我们有 ConcurrentHashMap<String, Set<String>> key 地图是什么 String ,及 value 是 ConcurrentHashSet .
2. 我需要移除 set map 设置 是 empty .
3. 我不能实现简单的删除 设置

我的问题有什么绝妙的解决办法吗?
