    • attribute

      public <T> ChannelBuilder attribute(io.netty.util.AttributeKey<T> key, Supplier<T> factory)
      Registers a AttributeKey to be filled when a new connection is created. This is meant as a simple way to attach data on a per-connection bases.
      Parameters:
      key - The key to assign
      factory - A factory that creates a new instance of the context data
