PoolUtils.ErodingPerKeyKeyedObjectPool

java.lang.Object
- org.apache.commons.pool2.PoolUtils.ErodingKeyedObjectPool<K,V>
- - org.apache.commons.pool2.PoolUtils.ErodingPerKeyKeyedObjectPool<K,V>

All Implemented Interfaces:

KeyedObjectPool<K,V>

Enclosing class:

PoolUtils
```
private static class PoolUtils.ErodingPerKeyKeyedObjectPool<K,V>
extends PoolUtils.ErodingKeyedObjectPool<K,V>
```
Extends ErodingKeyedObjectPool to allow erosion to take place on a per-key basis. Timing of erosion events is tracked separately for separate keyed pools.
