在Java中是否可以只签出cvsclient中的目录结构？

import org.netbeans.lib.cvsclient.CVSRoot;
import org.netbeans.lib.cvsclient.Client;
import org.netbeans.lib.cvsclient.connection.PServerConnection;

public class CVSExample {
    public static void main(String[] args) {
        // 创建CVS客户端连接
        CVSRoot cvsRoot = CVSRoot.parse(":pserver:username:password@hostname:/cvsroot");
        PServerConnection connection = new PServerConnection(cvsRoot);
        Client client = new Client(connection, null, null);

        try {
            // 打开连接
            client.open();

            // 设置签出选项
            client.setCheckoutByDate(false);

            // 执行签出操作
            client.checkout("path/to/directory");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭连接
            client.close();
        }
    }
}
