Method Detail

staleTime

public RefreshResult.Builder<T> staleTime(Instant staleTime)

Specify the time at which the value in this cache is stale, and all calls to CachedSupplier.get() should block to try to update the value. If this isn't specified, all threads will never block to update the value.

prefetchTime

public RefreshResult.Builder<T> prefetchTime(Instant prefetchTime)

Specify the time at which a thread that calls CachedSupplier.get() should trigger a cache prefetch. The exact behavior of a "prefetch" is defined when the cache is created with CachedSupplier.Builder.prefetchStrategy(CachedSupplier.PrefetchStrategy), and may either have one thread block to refresh the cache or have an asynchronous task reload the value in the background. If this isn't specified, the prefetch strategy will never be used and all threads will block to update the value when the staleTime(Instant) arrives.

build
