<s>[INST] package com.infomaximum.cluster;

public class ClusterInfo {
    private String host;
    private int port;

    public ClusterInfo(String host, int port) {
        this.host = host;
        this.port = port;
    }

    // getters and setters
    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }
}

How can I use a custom annotation to mark that ClusterInfo is a data class and that it should be converted to a protobuf object when generated into a different programming language?[/INST]
