Field Details

LOGGER

static final System.Logger LOGGER

The mutator logger

EMPTY

static final CacheEntryMutator EMPTY

Trivial CacheEntryMutator implementation that does nothing. New cache entries created within the context of a batch, in particular, do not require mutation.

Method Details

run

default void run()

Specified by:

run in interface Runnable

runAsync

CompletionStage<Void> runAsync()

Mutates the associated cache entry asynchronously.

Returns:

a stage that completes when the cache entry mutation completes.

withMaxIdle

CacheEntryMutator withMaxIdle(Supplier<Duration> maxIdle)

Applies a maximum idle duration to the mutated cache entry.

Parameters:

maxIdle - a provider of a maximum idle duration

Returns:

a reference to this mutator.

of

static CacheEntryMutator of(Iterable<CacheEntryMutator> mutators)

Returns a composite mutator that runs the specified mutators.

Parameters:

mutators - a number of mutators

Returns:

a composite mutator.
