    - #### getName

          public String getName()

      Description copied from interface: `Cache`
      A configured or generated name of this cache instance.
      Specified by:
        `getName` in interface `Cache<K,V>`
      Returns:
        name of this cache or null for anonymous caches.

    - #### get

          public V get(K key)

      Description copied from interface: `Cache`
      Returns a value associated by the given key, that contains a non expired value. If no value is present or it is expired the cache loader is invoked, if configured, or `null` is returned.
      Specified by:
        `get` in interface `Cache<K,V>`
      Parameters:
        `key` - key with which the specified value is associated
      Returns:
        the value associated with the specified key, or `null` if there was no mapping for the key.

    - #### containsKey

          public boolean containsKey(K key)

      Description copied from interface: `Cache`
      Returns true, if there is a mapping for the specified key.
      Specified by:
        `containsKey` in interface `Cache<K,V>`
      Parameters:
        `key` - key which association should be checked
      Returns:
        `true`, if this cache contains a mapping for the specified key

    - #### put

          public void put(K key,
                          V value)

      Description copied from interface: `Cache`
      Updates an existing cache entry for the specified key, so it associates the given value, or, insert a new cache entry for this key and value.
      Specified by:
        `put` in interface `Cache<K,V>`
      Parameters:
        `key` - key with which the specified value is associated
        `value` - value to be associated with the specified key

    - #### remove

          public void remove(K key)

      Description copied from interface: `Cache`
      Removes the mapping for a key from the cache if it is present.
      Specified by:
        `remove` in interface `Cache<K,V>`
      Parameters:
        `key` - key which mapping is to be removed from the cache, not null

      Description copied from interface: `Cache`
      Clear the cache.
      Specified by:

      initializes the implementation with additional parameters.
      Specified by:
        `initialize` in interface `ConfigurableImplementation`
      Parameters:
