      public BUILDER from(LruCacheConfig<K,V> prototype)
      Update this builder from an existing prototype instance. This method disables automatic service discovery.
      Parameters:
      prototype - existing prototype to update this builder from
      Returns:
      updated builder instance

    • from

      public BUILDER from(LruCacheConfig.BuilderBase<K,V,?,?> builder)
      Update this builder from an existing prototype builder instance.
      Parameters:
      builder - existing builder prototype to update this builder from
      Returns:
      updated builder instance

    • config

      public BUILDER config(Config config)
      Update builder from configuration (node of this type). If a value is present in configuration, it would override currently configured values.
      Specified by:
      config in interface Prototype.ConfiguredBuilder<K,V>
      Parameters:
      config - configuration instance used to obtain values to update this builder
      Returns:
      updated builder instance

    • capacity

      public BUILDER capacity(int capacity)
      Configure capacity of the cache. Defaults to 10000<K,V>.
      Parameters:
      capacity - maximal number of records in the cache before the oldest one is removed
