Example 31 with Node

use of io.nuls.network.model.Node in project nuls by nuls-io.

the class ServerChannelHandler method channelUnregistered.

@Override
public void channelUnregistered(ChannelHandlerContext ctx) throws Exception {
    super.channelUnregistered(ctx);
    SocketChannel channel = (SocketChannel) ctx.channel();
    String nodeId = IpUtil.getNodeId(channel.remoteAddress());
    Attribute<Node> nodeAttribute = channel.attr(AttributeKey.valueOf("node-" + nodeId));
    Node node = nodeAttribute.get();
    if (node != null && node.getDisconnectListener() != null) {

    }
// channelUnregistered之前，channel就已经close了，可以调用channel.isOpen()查看状态
// channel.close();
