ExpiringMap (MINA 2.0.13 API文档 - 即时通讯网(52im.net))

java.lang.Object
- org.apache.mina.util.ExpiringMap<K,V>

所有已实现的接口:

java.util.Map<K,V>
```
public class ExpiringMap<K,V>
extends java.lang.Object
implements java.util.Map<K,V>
```
A map with expiration. This class contains a worker thread that will periodically check this class in order to determine if any objects should be removed based on the provided time-to-live value.
