如何制作一个CaseInsensitiveConcurrentMap? [英] How to make a CaseInsensitiveConcurrentMap?

问题描述

我该如何实现

class CaseInsensitiveConcurrentMap<V> implements ConcurrentMap<String , V>

除了键是不区分大小写的比较之外，它与 ConcurrentHashMap< String，V> 一样工作吗?键不能转换为小写或大写.

which works just like ConcurrentHashMap<String , V> except that the keys are compared case-insensitively? The keys should not be converted to lowercase or uppercase.

请注意， Collections.synchronizedMap(new TreeMap< String，new MyCaseInsensitiveComparator())不是解决方案，因为它不允许并发并且错过了其他方法.

Note that Collections.synchronizedMap(new TreeMap<String, new MyCaseInsensitiveComparator()) is no solution as it allows no concurrency and misses the additional methods.

创建一个不区分大小写的 equals 和 hashCode 的类似String的类也不可行，因为必须将映射传递给以字符串为键的方法./p>

Creating a String-like class with case-insensitive equals and hashCode is no option either, since the map has to be passed to methods expecting strings as keys.

推荐答案

您尝试过

ConcurrentMap<String, Object> map = 
    new ConcurrentSkipListMap<String, Object>(
        String.CASE_INSENSITIVE_ORDER);
