Usage

From source file:Main.java

    ConcurrentHashMap<Integer, UUID> concurrentHashMap = new ConcurrentHashMap<>();

    for (int i = 0; i < 100; i++) {
        concurrentHashMap.put(i, UUID.randomUUID());
    }/*from  w w  w  .ja v a2 s  . c o  m*/

    int threshold = 1;

    concurrentHashMap.forEachValue(threshold, System.out::println);

    concurrentHashMap.forEach((id, uuid) -> {
        if (id % 10 == 0) {
            System.out.println(String.format("%s: %s", id, uuid));
        }
    });

    String searchResult = concurrentHashMap.search(threshold, (id, uuid) -> {
        if (String.valueOf(uuid).contains(String.valueOf(id))) {
