CacheMap (hybris Commerce Suite 2011)

All Known Implementing Classes:

DefaultCacheMap
```
public interface CacheMap
```
Defines replaceable cache map interface to be used in hybris 5.
It is possible to configure DefaultCacheRegion together with custom map implementation. Nevertheless it is recommended to define whole CacheRegion.
This implementation should not be thread safe. Thread safety and synchronization is of the CacheRegion responsibility.
