本文整理了Java中org.apache.avro.io.Encoder.writeIndex()方法的一些代码示例，展示了Encoder.writeIndex()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Encoder.writeIndex()方法的具体详情如下：
包路径：org.apache.avro.io.Encoder
类名称：Encoder
方法名：writeIndex

Encoder.writeIndex介绍

[英]Call this method to write the tag of a union. As an example of usage, let's say you want to write a union, whose second branch is a record consisting of an Long field and a Boolean field. Your code would look something like this:

out.writeIndex(1); 
out.writeLong(record.longField); 
out.writeBoolean(record.boolField);

[中]调用此方法以写入联合的标记。作为一个使用示例，假设您想要编写一个联合，其第二个分支是一个由长字段和布尔字段组成的记录。您的代码如下所示：

out.writeIndex(1); 
out.writeLong(record.longField); 
out.writeBoolean(record.boolField);
