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

TypeCodec.duration介绍

[英]Returns the default codec for the DataType#duration().

This codec maps duration types to the driver's built-in Duration class, thus providing a more user-friendly mapping than the low-level mapping provided by regular #custom(DataType.CustomType).

The returned instance is a singleton.
[中]返回数据类型#duration（）的默认编解码器。
此编解码器将持续时间类型映射到驱动程序的内置持续时间类，从而提供比常规#自定义（DataType.CustomType）提供的低级映射更友好的映射。
返回的实例是一个单例。

private void assertCodec(String input, Duration expected) {
  // serialize + deserialize
  ByteBuffer bytes = TypeCodec.duration().serialize(Duration.from(input), V4);
  Duration actual = TypeCodec.duration().deserialize(bytes, V4);
  assertThat(actual).isEqualTo(expected);
  // format + parse
  String format = TypeCodec.duration().format(Duration.from(input));
  actual = TypeCodec.duration().parse(format);
  assertThat(actual).isEqualTo(expected);
  // parse alone
  actual = TypeCodec.duration().parse(input);
  assertThat(actual).isEqualTo(expected);
 }
}
