Method Details

prefetchStrategy

public CachedSupplier.Builder<T> prefetchStrategy(CachedSupplier.PrefetchStrategy prefetchStrategy)

Configure the way in which data in the cache should be pre-fetched when the data's RefreshResult.prefetchTime() arrives. By default, this uses the OneCallerBlocks strategy, which will block a single CachedSupplier.get() caller to update the value.

staleValueBehavior

public CachedSupplier.Builder<T> staleValueBehavior(CachedSupplier.StaleValueBehavior staleValueBehavior)

Configure the way the cache should behave when a stale value is retrieved or when retrieving a value fails while the cache is stale. By default, this uses CachedSupplier.StaleValueBehavior.STRICT.

cachedValueName

public CachedSupplier.Builder<T> cachedValueName(String cachedValueName)

Configures a name for the cached value. This name will be included with logs emitted by this supplier, to aid in debugging. By default, this uses "unknown".

clock

public CachedSupplier.Builder<T> clock(Clock clock)

Configure the clock used for this cached supplier. Configurable for testing.

build

public CachedSupplier<T> build()

Create a CachedSupplier using the current configuration of this builder.
