  • Method Details

    • clear

      public void clear()
      Clears the cache by truncating the configured cache's set (in the configured namespace).
      Specified by:
      clear in interface Cache

    • evict

      public void evict​(Object key)
      Deletes the key from Aerospike database.
      Specified by:
      evict in interface Cache
      Parameters:
      key - The key to delete.

    • getName

      public String getName()
      Get cache's name.
      Specified by:
      getName in interface Cache
      Returns:
      The cache's name.

    • getNativeCache

      public Object getNativeCache()
      Get the underlying native cache provider - the Aerospike client.
      Specified by:
      getNativeCache in interface Cache
      Returns:
      The aerospike client.

    • get

      public <T> T get​(Object key, Callable<T> valueLoader)
      Return the value (bins) from the Aerospike database to which this cache maps the specified key, obtaining that value from valueLoader if necessary. This method provides a simple substitute for the conventional "if cached, return; otherwise create, cache and return" pattern.
      Specified by:
      get in interface Cache
      Parameters:
      key - The key whose associated value is to be returned.
      valueLoader - The value loader that might contain the value (bins).
      Returns:
      The value (bins) to which this cache maps the specified key.

    • get

      public <T> T get​(Object key, Class<T> type)
      Return the value (bins) from the Aerospike database to which this cache maps the specified key. Generically specifying a type that return value will be cast to.
      Specified by:
      get in interface Cache
      Parameters:
      key - The key whose associated value (bins) is to be returned.
      type - The required type of the returned value (may be null to bypass a type check; in case of a null value found in the cache, the specified type is irrelevant).
      Returns:
      The value (bins) to which this cache maps the specified key (which may be null itself), or also null if the cache contains no mapping for this key.

    • get

      public Cache.ValueWrapper get​(Object key)
      Returns the value (bins) from the Aerospike database to which this cache maps the specified key. Returns null if the cache contains no mapping for this key; otherwise, the cached value (which may be null itself) will be returned in a Cache.ValueWrapper.
      Specified by:
      get in interface Cache
      Parameters:
      key - The key whose associated value (bins) is to be returned.
      Returns:
      The value (bins) to which this cache maps the specified key, contained within a Cache.ValueWrapper which may also hold a cached null value. A straight null being returned means that the cache contains no mapping for this key.

    • put

      public void put​(Object key, Object value)
      Write the key-value pair to Aerospike database.
      Specified by:
      put in interface Cache
      Parameters:
      key - The key to write.
      value - The value to write.

    • putIfAbsent

      public Cache.ValueWrapper putIfAbsent​(Object key, Object value)
      Write the key-value pair to Aerospike database if the key doesn't already exists.
      Specified by:
      putIfAbsent in interface Cache
      Parameters:
      key - The key to write.
      value - The value (bins) to write.
      Returns:
      In case the key already exists return the existing value, else return null.
