All Known Implementing Classes:

Enclosing interface:

ConfigurableCacheMap
```
public static interface ConfigurableCacheMap.EvictionPolicy
```
An eviction policy is an object that the cache provides with access information, and when requested, the eviction policy selects and evicts entries from the cache. If the eviction policy needs to be aware of changes to the cache, it must implement the MapListener interface; if it does, it will automatically be registered to receive MapEvents.
