MemoryConstrainedCacheManager (Apache Shiro 1.7.0 API)

java.lang.Object
- org.apache.shiro.cache.AbstractCacheManager
- - org.apache.shiro.cache.MemoryConstrainedCacheManager

All Implemented Interfaces:

CacheManager, Destroyable
```
public class MemoryConstrainedCacheManager
extends AbstractCacheManager
```
Simple memory-only based CacheManager implementation usable in production environments. It will not cause memory leaks as it produces Caches backed by SoftHashMaps which auto-size themselves based on the runtime environment's memory limitations and garbage collection behavior.
While the Cache instances created are thread-safe, they do not offer any enterprise-level features such as cache coherency, optimistic locking, failover or other similar features. For more enterprise features, consider using a different CacheManager implementation backed by an enterprise-grade caching product (Hazelcast, EhCache, TerraCotta, Coherence, GigaSpaces, etc, etc).
