LongCache.Java:
LongCacheObject cacheObject = (LongCacheObject)cachedObjectsHash.get(key);
public final Object get(long key) {
int i = indexOfKey(key); //问题在这里，按照HASH算法，有可能是多个thread id(key)对应一个hash值i的
//If not in the map return null
if (i<0) {
return null;
}
else {
return values;//而这里直接返回了一个i的object,怎么能保证这个object就是唯一的呢？不会是每次遇到
重复的hash值就把上次的覆盖掉吧？？就是不懂这里，请高手指点指点
}
