com.centit.support.common

类 CachedMap<K,T>

java.lang.Object

com.centit.support.common.AbstractCachedObject<Map<K,T>>

com.centit.support.common.CachedMap<K,T>

类型参数:

K - id 键值类型

T - target 缓存对象的类型

所有已实现的接口:

ICachedObject<Map<K,T>>

public class CachedMap<K,T>
extends AbstractCachedObject<Map<K,T>>

用 ConcurrentHashMap 缓存对象，每个对象 自己维护缓存策略

CachedMap

public CachedMap()

CachedMap

public CachedMap(Function<K,T> refresher,
                 long freshPeriod,
                 int initialCapacity)

构造函数

参数:

refresher - 重新获取代码的接口

freshPeriod - 保鲜时间，单位为秒；也是重新刷新时间 它的意思不是每隔一段时间就刷新，而是在获取数据是检查是否超时，如果超时则刷新

initialCapacity - The implementation performs internal sizing to accommodate this many elements.
