Class CacheMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

com.mxixm.fastboot.weixin.util.CacheMap<K,V>

All Implemented Interfaces:

Map<K,V>

public class CacheMap<K,V>
extends AbstractMap<K,V>

FastBootWeixin CacheMap 用来存储短暂对象的缓存类，实现Map接口，内部有一个定时器用来清除过期（30秒）的对象。 扩展了两个功能

Method Summary

Modifier and Type	Method and Description
static <K,V> CacheMap.Builder<K,V>	builder()
static void	clearOverflowCache(CacheMap map) 清理超过限制的缓存
static void	clearTimeoutCache(CacheMap map)
TreeSet<Map.Entry<K,V>>	entrySet() remove其实是通过这个来实现的，但是这里功能明显导致删除会失败，结果会内存溢出，所以我重写了remove方法 这里的entrySet实现可能是有点问题的，因为返回的是一个新的实例。
