      • doWriteSingle

        protected int doWriteSingle​(io.netty.channel.ChannelOutboundBuffer in)
                     throws Exception
        Description copied from class: AbstractEpollStreamChannel
        Attempt to write a single object.
        Overrides:
        doWriteSingle in class AbstractEpollStreamChannel
        Parameters:
        in - the collection which contains objects to write.
        Returns:
        The value that should be decremented from the write quantum which starts at ChannelConfig.getWriteSpinCount(). The typical use cases are as follows:
        • 0 - if no write was attempted. This is appropriate if an empty ByteBuf (or other empty content) is encountered
        • 1 - if a single call to write data was made to the OS
        • ChannelUtils.WRITE_STATUS_SNDBUF_FULL - if an attempt to write data was made to the OS, but no data was accepted
        Throws:
        Exception - If an I/O error occurs.

      • peerCredentials

        public io.netty.channel.unix.PeerCredentials peerCredentials()
                                                      throws IOException
        Returns the unix credentials (uid, gid, pid) of the peer SO_PEERCRED
        Throws:
        IOException
