Class ThreadLocalCache

  • public class ThreadLocalCache
    extends Object
    A generic cache for "stuff" that is only needed for the lifetime of a web request or scheduled job. The most important rule for this cache is use custom types for keys. If you use some generic key type like a String, you will inevitably clobber someone else's cached data.

    Don't use the ThreadLocalCache directly: use the ThreadLocalCacheAccessor to give you a typesafe container around the cache.
