java.lang.Object
growthbook.sdk.java.stickyBucketing.InMemoryStickyBucketServiceImpl

  • Constructor Details

    • InMemoryStickyBucketServiceImpl

      public InMemoryStickyBucketServiceImpl()
      Constructs a new InMemoryStickyBucketServiceImpl backed by a thread-safe map, suitable for use with GrowthBookClient where evaluations run concurrently.

    • InMemoryStickyBucketServiceImpl

      public InMemoryStickyBucketServiceImpl(Map<String,StickyAssignmentsDocument> localStorage)
      Constructs a new InMemoryStickyBucketServiceImpl with the specified local storage.
      Parameters:
      localStorage - a map to store sticky assignments documents in memory. The map is used directly as the backing storage, so assignments saved by this service are visible to the caller and vice versa. A plain map (e.g. HashMap) is only safe when the service is used from a single thread; pass a thread-safe ConcurrentMap (e.g. ConcurrentHashMap) when the service is shared by a GrowthBookClient evaluating on multiple threads. A null map falls back to an empty ConcurrentHashMap.
