  • Constructor Details

    • ReactorNetty2TcpClient

      public ReactorNetty2TcpClient(String host, int port, TcpMessageCodec<P> codec)
      Simple constructor with the host and port to use to connect to.

      This constructor manages the lifecycle of the TcpClient and underlying resources such as ConnectionProvider, LoopResources, and ChannelGroup.

      For full control over the initialization and lifecycle of the TcpClient, use ReactorNetty2TcpClient(TcpClient, TcpMessageCodec).

      Parameters:
      host - the host to connect to
      port - the port to connect to
      codec - for encoding and decoding the input/output byte streams

    • ReactorNetty2TcpClient

      public ReactorNetty2TcpClient(Function<reactor.netty5.tcp.TcpClient,reactor.netty5.tcp.TcpClient> clientConfigurer, TcpMessageCodec<P> codec)
      A variant of ReactorNetty2TcpClient(String, int, TcpMessageCodec) that still manages the lifecycle of the TcpClient and underlying resources, but allows for direct configuration of other properties of the client through a Function<TcpClient, TcpClient>.
      Parameters:
      clientConfigurer - the configurer function
      codec - for encoding and decoding the input/output byte streams

    • ReactorNetty2TcpClient

      public ReactorNetty2TcpClient(reactor.netty5.tcp.TcpClient tcpClient, TcpMessageCodec<P> codec)
      Constructor with an externally created TcpClient instance whose lifecycle is expected to be managed externally.
      Parameters:
      tcpClient - the TcpClient instance to use
      codec - for encoding and decoding the input/output byte streams
