    • transformCache

      private com.github.benmanes.caffeine.cache.Cache<Optional<String>,com.bazaarvoice.jolt.JoltTransform> transformCache
      It is a cache for transform objects. It keeps values indexed by jolt specification string. For some cases the key could be empty. It means that it represents default transform (e.g. for custom transform when there is no jolt-record-spec specified).
