Examples with ServerBootstrap io.netty.bootstrap.ServerBootstrap used on opensource projects

Example 16 with ServerBootstrap

use of io.netty.bootstrap.ServerBootstrap in project neo4j by neo4j.

the class NettyServer method start.

@Override
public void start() throws Throwable {
    // The boss thread accepts new incoming connections and chooses a worker thread to be responsible for the
    // IO of the new connection. We expect new connections to be (comparatively) rare, so we allocate a single
    // thread for this.
    // TODO: In fact, dedicating a whole thread to sit and spin in #select for new connections may be a waste of
    // time, we could have the same event loop groups for both handling new connections and for handling events
    // on existing connections
    bossGroup = new NioEventLoopGroup(1, tf);
    // These threads handle live channels. Each thread has a set of channels it is responsible for, and it will
    // continuously run a #select() loop to react to new events on these channels.

    for (ProtocolInitializer initializer : bootstrappers) {
        try {
