      Parameters:
      key - the string key
      Returns:
      the Serializable value, return null if the key does not exist or if the key is null

    • keySet

      public Set<String> keySet()
      Description copied from interface: Cache
      Returns the set of all keys stored in the cache.
      Returns:
      the Set of all keys

    • invalidate

      public void invalidate(String key)
      Description copied from interface: Cache
      Invalidate the given key
      Parameters:
      key - , the key to remove from the cache, if null will do nothing

    • invalidateLocal

      public void invalidateLocal(String key)
      Description copied from interface: CacheManagement
      Invalidates the given key locally. Does not propagate invalidations.
      Parameters:
      key - the key to remove from the cache

    • invalidateAll

      public void invalidateAll()
      Description copied from interface: Cache
      Invalidate all key-value stored in the cache

    • invalidateLocalAll

      public void invalidateLocalAll()
      Description copied from interface: CacheManagement
      Invalidates all keys locally. Does not propagate invalidations.

    • put

      public void put(String key, Serializable value)
      Description copied from interface: Cache
      Put method to store a Serializable value
      Parameters:
      key - the string key, if null, the value will not be stored
      value - the value to store, if null, the value will not be stored

    • putLocal

      public void putLocal(String key, Serializable value)
      Description copied from interface: CacheManagement
      Stores a Serializable value into the cache locally. Does not propagate invalidations.

    • hasEntry

      public boolean hasEntry(String key)
      Description copied from interface: Cache

      Parameters:
      key - the string key
      Returns:
      true if a corresponding entry exists, false otherwise

    • getSize

      public long getSize()
      Description copied from interface: CacheManagement
      Returns this cache size (approximate number of entries), or -1 if the number of entries is unknown or too expensive to compute.
      Returns:
      the approximate number of entries, or -1
