如何将多个元素附加到协议缓冲区中的repeatedField？

import com.example.protobuf.ExampleMessage;

// 创建协议缓冲区实例
ExampleMessage.MyMessage.Builder myMessageBuilder = ExampleMessage.MyMessage.newBuilder();

// 创建要添加到repeatedField的元素对象1
ExampleMessage.MyElement.Builder element1Builder = ExampleMessage.MyElement.newBuilder();
element1Builder.setId(1);
element1Builder.setName("Element 1");
ExampleMessage.MyElement element1 = element1Builder.build();

// 将元素对象1添加到repeatedField
myMessageBuilder.addElements(element1);

// 创建要添加到repeatedField的元素对象2
ExampleMessage.MyElement.Builder element2Builder = ExampleMessage.MyElement.newBuilder();
element2Builder.setId(2);
element2Builder.setName("Element 2");
ExampleMessage.MyElement element2 = element2Builder.build();

// 将元素对象2添加到repeatedField
myMessageBuilder.addElements(element2);

// 获取最终的协议缓冲区消息
ExampleMessage.MyMessage myMessage = myMessageBuilder.build();
