  • Method Details

    • put

      public void put(K key, V value)
      Description copied from interface: ICache

      Insert a new value into the cache.

      Specified by:
      put in interface ICache<K,V>
      Parameters:
      key - the key of the new entry
      value - the value to be cached

    • get

      public V get(K key)
      Description copied from interface: ICache

      Retrieve a value from the cache.

      Specified by:
      get in interface ICache<K,V>
      Parameters:
      key - the key of the value to be retrieved
      Returns:
      the retrieved value, or null if no value exists for the specified key.

    • get

      public V get(K key, ICacheEntryValidityChecker<? super K,? super V> validityChecker)
      Description copied from interface: ICache

      Retrieve a value from the cache, using the specified validity checker to ensure the entry is still valid. If the cache already has a default validity checker, this method should override this setting and use the one specified instead.

      Specified by:
      get in interface ICache<K,V>
      Parameters:
      key - the key of the value to be retrieved
      validityChecker - the validity checker to be used to ensure the entry is still valid.
      Returns:
      the retrieved value, or null if no value exists for the specified key.

    • keySet

      public Set<K> keySet()

      Returns all the keys contained in this cache. Note this method might return keys for entries that are already invalid, so the result of calling get(Object) for these keys might be null.

      Specified by:
      keySet in interface ICache<K,V>
      Returns:
      the complete set of cache keys. Might include keys for already-invalid (non-cleaned) entries.

      Description copied from interface: ICache

    • clearKey

      public void clearKey(K key)
      Description copied from interface: ICache

      Clears a specific entry in the cache.

      Specified by:
      clearKey in interface ICache<K,V>
      Parameters:
      key - the key of the entry to be cleared.
