      public WriteOperation createWriteOperation​(SocketChannelContext context, java.lang.Object message, java.util.function.BiConsumer<java.lang.Void,​java.lang.Exception> listener)
      Description copied from interface: NioChannelHandler
      This method is called when a message is queued with a channel. It can be called from any thread. This method should validate that the message is a valid type and return a write operation object to be queued with the channel
      Specified by:
      createWriteOperation in interface NioChannelHandler
      Parameters:
      context - the channel context
      message - the message
      listener - the listener to be called when the message is sent
      Returns:
      the write operation to be queued

    • channelActive

      Description copied from interface: NioChannelHandler
      This method is called when the channel is active for use.
      Specified by:
      channelActive in interface NioChannelHandler

    • writeToBytes

      public java.util.List<FlushOperation> writeToBytes​(WriteOperation writeOperation)
      Description copied from interface: NioChannelHandler
      This method is called on the event loop thread. It should serialize a write operation object to bytes that can be flushed to the raw nio channel.
      Specified by:
      writeToBytes in interface NioChannelHandler
      Parameters:
      writeOperation - to be converted to bytes
      Returns:
      the operations to flush the bytes to the channel
