All Known Implementing Classes:

CacheImpl
```
public interface Cache
```
Provides an API for querying/managing the second level cache regions.
CAUTION: None of these methods respect any isolation or transactional semantics associated with the underlying caches. Specifically, evictions perform an immediate "hard" removal outside any transactions and/or locking scheme(s).

  - containsEntity
```
boolean containsEntity(Class entityClass,
                     Serializable identifier)

  - evictNaturalIdRegion
```
void evictNaturalIdRegion(Class naturalIdClass)
```
    Evicts all naturalId data from the given region (i.e. for all entities of type).
    
    Parameters:
    naturalIdClass - The naturalId class.
  - evictNaturalIdRegion
```
void evictNaturalIdRegion(String naturalIdName)
```
    Evicts all naturalId data from the given region (i.e. for all entities of type).
    
    Parameters:
    naturalIdName - The naturalId name.
  - evictNaturalIdRegions
```
void evictNaturalIdRegions()
```
    Evict data from all naturalId regions.
  - containsCollection
```
boolean containsCollection(String role,
                         Serializable ownerIdentifier)
```
    Determine whether the cache contains data for the given collection.
    The semantic here is whether the cache contains data visible for the current call context.
    
    Parameters:
    role - The name of the collection role (in form [owner-entity-name].[collection-property-name]) whose regions should be evicted.
    ownerIdentifier - The identifier of the owning entity
    
    Returns:
    True if the underlying cache contains corresponding data; false otherwise.
  - evictCollection
```
void evictCollection(String role,
                   Serializable ownerIdentifier)
```
    Evicts the cache data for the given identified collection instance.
    
    Parameters:
    role - The "collection role" (in form [owner-entity-name].[collection-property-name]).
    ownerIdentifier - The identifier of the owning entity
  - evictCollectionRegion
```
void evictCollectionRegion(String role)
```
    Evicts all entity data from the given region (i.e. evicts cached data for all of the specified collection role).
    
    Parameters:
    role - The "collection role" (in form [owner-entity-name].[collection-property-name]).
  - evictCollectionRegions
```
void evictCollectionRegions()
```

  - containsQuery
```
boolean containsQuery(String regionName)
```

    The semantic here is whether the cache contains any data for the given region name since query result caches are not transactionally isolated.
    
    Parameters:
    regionName - The cache name given to the query.
    
    Returns:
    True if the underlying cache contains corresponding data; false otherwise.
  - evictDefaultQueryRegion
```
void evictDefaultQueryRegion()
```
    Evicts all cached query results from the default region.
  - evictQueryRegion
```
void evictQueryRegion(String regionName)
```
    Evicts all cached query results under the given name.
    
    Parameters:
    regionName - The cache name associated to the queries being cached.
