Constructor Detail

DefaultCacheController

public DefaultCacheController(CacheConfiguration configuration)

Method Detail

init

@PostConstruct
public void init()

Reads configuration and creates registry for cache regions required

invalidate

public void invalidate(CacheKey key)

Performs key invalidation from cache.
Method checks invalidation filters and cache registry.

Specified by:

invalidate in interface CacheController

remove

public void remove(CacheKey key)

Legacy method implemented just to implement lazy computing in AbstractCacheUnit

Specified by:

remove in interface CacheController

getWithLoader

public <T> T getWithLoader(CacheKey key,
                           CacheValueLoader<T> loader)
                    throws CacheValueLoadException

Gets stored value from cache. If value is not available loader is invoked.

Specified by:

getWithLoader in interface CacheController

Throws:

CacheRegionNotSpecifiedException

CacheValueLoadException

get

public <T> T get(CacheKey key)

Description copied from interface: CacheController

Gets value stored in the cache. If value is not already loaded returns NULL.

Specified by:

get in interface CacheController

resolveQueryRegionsForInvalidation

public java.util.Collection<CacheRegion> resolveQueryRegionsForInvalidation(CacheKey key)

returns all regions handling queries. There may be more than one region handling queries.

resolveRegionsForInvalidation

public java.util.List<CacheRegion> resolveRegionsForInvalidation(CacheKey key)

Returns cache regions for invalidation.
Only regions which can store key provided.

resolveCacheRegionForAdd

public CacheRegion resolveCacheRegionForAdd(CacheKey key)
                                     throws CacheRegionNotSpecifiedException

Method used to resolve cache region.
Resolved cache region can be used as a parameter to invalidate() and getOrAdd().
It can improve performance when many operations are performed.
Parameter regionName should be stored in transaction (or other) context.
If the forInvalidation flag is set and no region name specified region proxy can be returned. This region proxy invalidates given key in all defined cache region.

Throws:

CacheRegionNotSpecifiedException

getResolvers

public CacheRegionResolver[] getResolvers()

Returns:

the resolvers

getFilters

public java.util.List<InvalidationFilter> getFilters()

getRegions

public java.util.List<CacheRegion> getRegions()

Description copied from interface: CacheController

Returns all regions used in this controller.

Specified by:

getRegions in interface CacheController

clearCache

public void clearCache(CacheRegion region)

Clears cache

Specified by:

clearCache in interface CacheController
