Method Detail

build

public static <T> CallableResultCache<T> build(@NotNull
                                               com.google.common.cache.CacheBuilder<Object,Object> builder)

Builds a simple callable result cache using the supplied builder. The cache has no support for user-contaxt driven invalidation.

build

public static <T> CallableResultCache<T> build(@NotNull
                                               com.google.common.cache.CacheBuilder<Object,Object> builder,
                                               CacheAwareness.CacheInfo... cacheIds)

Builds a simple callable result cache using the supplied builder. Supplied cacheIds will be used in user-context driven invalidation. see CacheAwareness.withValuesOlderThanTimestampReloaded(BambooRunnables.ThrowingX, long, CacheAwareness.CacheInfo...)

buildAlwaysInvalidating

public static <T> CallableResultCache<T> buildAlwaysInvalidating(@NotNull
                                                                 com.google.common.cache.CacheBuilder<Object,Object> builder,
                                                                 CacheAwareness.CacheInfo... cacheIds)

Builds a simple callable result cache using the supplied builder. The cache will be invalidated again when invalidate is called while cache load is taking place. See build(com.google.common.cache.CacheBuilder, com.atlassian.bamboo.util.CacheAwareness.CacheInfo...), AlwaysInvalidatingCacheDecorator

stats

public com.google.common.cache.CacheStats stats()

Returns:

cache statistics

call

public T call(@NotNull
              Callable<T> callable,
              Object... keys)

callChecked

public T callChecked(@NotNull
                     Callable<T> callable,
                     Object... keys)
              throws ExecutionException

executes a callable if no fresh result is cached, throws a checked exception See LoadingCache.get(Object)

Throws:

ExecutionException
