本文整理了Java中com.datastax.driver.core.Row.getSet方法的一些代码示例，展示了Row.getSet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。Row.getSet方法的具体详情如下：
包路径：com.datastax.driver.core.Row
类名称：Row
方法名：getSet

Row.getSet介绍

[英]Returns the ith value of this row as a set.
[中]以集合形式返回此行的第i个值。

代码示例

private static String buildSetValue(Row row, int i, CassandraType elemType)
{
  return buildArrayValue(row.getSet(i, elemType.javaType), elemType);
}

代码示例来源：origin: apache/nifi

TypeCodec firstCodec = codecRegistry.codecFor(firstArg);
if (dataType.equals(DataType.set(firstArg))) {
  return row.getSet(i, firstCodec.getJavaType());
} else if (dataType.equals(DataType.list(firstArg))) {
  return row.getList(i, firstCodec.getJavaType());
