Is it possible to get the current weight of a cache?

[ken-schneider]

Hi, if I set up a cache with maximumWeight, is there an API available to calculate current weight of the cache similar to cache.estimatedSize()? Or is what's being returned from cache.estimatedSize() in a weighted cache the current weight? Thanks!

Caffeine.newBuilder()
            .executor(context().dispatcher())
            .maximumWeight(someWeightInBytes)
            .weigher(new SomeWeigher())
            .buildAsync((request, executor) -> load(request));

Yes, you can use the policy api (wiki, javadoc) for these configuration-specific inspections. That is a bit hidden to not pollute the main api and keep it simpler, while also not blocking users by only offering an overly generic set of methods. Since it is a bit of a dumping ground those apis are less polished, so sorry if it could be a little nicer as it was added to as needed.

var eviction = cache.policy().eviction().orElseThrow()
long currentWeight = eviction.weightedSize().orElseThrow()
