CacheManager (jdonframework 6.9 API)

java.lang.Object
- com.jdon.controller.cache.CacheManager

所有已实现的接口:

Startable
```
public class CacheManager
extends Object
implements Startable
```
Cacahe Managerment Pattern Client objects request objects from a CacheManager object by calling its fetchObject method. The argument to the fetchObject method is an CacheKey object that identifies the object to fetch. The fetchObject method works by first calling the Cache object’s fetchObject method. there is one CacheManager in jdon container, you can get it from the container, do not need create it.
