    • getOrSet

      Object getOrSet(String key, Supplier<Object> provider, Duration timeout, Duration lastAccessTimeout, IStruct metadata)
      Tries to get an object from the cache, if not found, it will call the lambda to get the value and store it in the cache with the default timeout and last access timeout

      This is a convenience method to avoid the double lookup pattern

      var value = cache.getOrSet( "myKey", () -> { return "myValue"; });

      This is the same as: var value = cache.get( "myKey" ).orElseGet( () -> { var value = "myValue"; cache.set( "myKey", value ); return value; });

      This method is thread safe and will only call the lambda once if the key is not found in the cache

      Parameters:
      key - The key to retrieve
      provider - The lambda to call if the key is not found
      timeout - The timeout in seconds
      lastAccessTimeout - The last access timeout in seconds
      metadata - The metadata to store

    • getOrSet

      Object getOrSet(String key, Supplier<Object> provider, Duration timeout, Duration lastAccessTimeout)

      Parameters:
      key - The key to retrieve
      provider - The lambda to call if the key is not found
      timeout - The timeout in seconds
      lastAccessTimeout - The last access timeout in seconds
      Returns:
      The object

    • getOrSet

      Object getOrSet(String key, Supplier<Object> provider, Duration timeout)

    • getOrSet

      Object getOrSet(String key, Supplier<Object> provider)
