方法的一些代码示例,展示了ZoneOffsetTransition.getOffsetAfter()
的具体用法。这些代码示例主要来源于Github
/Stackoverflow

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。ZoneOffsetTransition.getOffsetAfter()
方法的具体详情如下:
包路径:java.time.zone.ZoneOffsetTransition
类名称:ZoneOffsetTransition
方法名:getOffsetAfter
[英]Gets the offset after the transition.
This is the offset in use on and after the instant of the transition.
[中]获取转换后的偏移量。
这是过渡瞬间和之后使用的偏移量。
