Interface AsyncCacheLoader.Context<K,V>

Enclosing interface:

AsyncCacheLoader<K,V>

public static interface AsyncCacheLoader.Context<K,V>

Relevant context information for a single load request.

Rationale: Instead of a rather long parameter list, we define an interface. This allows us later to add some information without breaking implementations of the AsyncCacheLoader. The context does not include the cache, since the loader should not depend on it and do any other operations on the cache while loading.

Method Summary

Modifier and Type	Method and Description
CacheEntry<K,V>	getCurrentEntry() Current entry in the cache.
Executor	getExecutor() The configured executor for async operations.
K	getKey() Cache key for the load request.
Executor	getLoaderExecutor() The configured loader executor.
long	getLoadStartTime() Time in millis since epoch of start of load operation

Method Detail

getLoadStartTime

long getLoadStartTime()

Time in millis since epoch of start of load operation

getKey

K getKey()

Cache key for the load request. Although the key is a call parameter it is repeated here, so users can choose to pass on the key or the whole context.

getExecutor

Executor getExecutor()

The configured executor for async operations.

See Also:

Cache2kBuilder.executor(Executor)

getLoaderExecutor

Executor getLoaderExecutor()

The configured loader executor.

See Also:

Cache2kBuilder.loaderExecutor(Executor)

getCurrentEntry

CacheEntry<K,V> getCurrentEntry()

Current entry in the cache. The entry is available if the load is caused by a reload or refresh. If expired before, null is returned. If Cache2kBuilder.keepDataAfterExpired(boolean) is enabled, also an expired entry is provided to the loader for optimization purposes. See also the description of Cache2kBuilder.keepDataAfterExpired(boolean) and Cache2kBuilder.refreshAhead(boolean).
