20.2. Permissions
Access to a CacheManager or a Cache is controlled using a set of required permissions. Permissions control the type of action that is performed on the CacheManager or Cache, rather than the type of data being manipulated. Some of these permissions can apply to specifically name entities, such as a named cache. Different types of permissions are available depending on the entity.
| Permission | Function | Description |
|---|---|---|
| CONFIGURATION | defineConfiguration | Whether a new cache configuration can be defined. |
| LISTEN | addListener | Whether listeners can be registered against a cache manager. |
| LIFECYCLE | stop, start | Whether the cache manager can be stopped or started respectively. |
| ALL | A convenience permission which includes all of the above. |
| Permission | Function | Description |
|---|---|---|
| READ | get, contains | Whether entries can be retrieved from the cache. |
| WRITE | put, putIfAbsent, replace, remove, evict | Whether data can be written/replaced/removed/evicted from the cache. |

| BULK_READ | keySet, values, entrySet,query | Whether bulk retrieve operations can be executed. |
| BULK_WRITE | clear, putAll | Whether bulk write operations can be executed. |

| ALL | A convenience permission which includes all of the above. | |

Note
Some permissions may need to be combined with others in order to be useful. For example, EXEC with READ or with WRITE.
