本文整理了Java中java.time.ZoneOffset.from()方法的一些代码示例，展示了ZoneOffset.from()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。ZoneOffset.from()方法的具体详情如下：
包路径：java.time.ZoneOffset
类名称：ZoneOffset
方法名：from

ZoneOffset.from介绍

[英]Obtains an instance of ZoneOffset from a temporal object.

A TemporalAccessor represents some form of date and time information. This factory converts the arbitrary temporal object to an instance of ZoneOffset.

The conversion uses the TemporalQueries#offset() query, which relies on extracting the ChronoField#OFFSET_SECONDS field.

This method matches the signature of the functional interface TemporalQueryallowing it to be used in queries via method reference, ZoneOffset::from.
[中]从时间对象获取ZoneOffset的实例。
临时助理代表某种形式的日期和时间信息。该工厂将任意时间对象转换为ZoneOffset的实例。
转换使用TemporalQueries#offset（）查询，该查询依赖于提取ChronoField#offset_SECONDS字段。
此方法匹配函数接口TemporalQueryLow的签名，通过方法引用ZoneOffset:：from将其用于查询。
