包路径：org.threeten.bp.zone.ZoneRules
类名称：ZoneRules

ZoneRules介绍

[英]The rules defining how the zone offset varies for a single time-zone.

The rules model all the historic and future transitions for a time-zone. ZoneOffsetTransition is used for known transitions, typically historic. ZoneOffsetTransitionRule is used for future transitions that are based on the result of an algorithm.

The rules are loaded via ZoneRulesProvider using a ZoneId. The same rules may be shared internally between multiple zone IDs.

Serializing an instance of ZoneRules will store the entire set of rules. It does not store the zone ID as it is not part of the state of this object.

A rule implementation may or may not store full information about historic and future transitions, and the information stored is only as accurate as that supplied to the implementation by the rules provider. Applications should treat the data provided as representing the best information available to the implementation of this rule.

Specification for implementors

The supplied implementations of this class are immutable and thread-safe.
[中]定义单个时区的分区偏移量如何变化的规则。
这些规则为时区的所有历史和未来过渡建模。ZoneOffsetTransition用于已知的过渡，通常是历史过渡。ZoneOffsetTransitionRule用于基于算法结果的未来转换。
使用ZoneId通过ZoneRulesProvider加载规则。多个区域ID之间可以在内部共享相同的规则。
序列化ZoneRules实例将存储整个规则集。它不存储区域ID，因为它不是此对象状态的一部分。
规则实现可能存储也可能不存储有关历史和未来转换的完整信息，存储的信息仅与规则提供程序提供给实现的信息一样准确。应用程序应将提供的数据视为代表执行此规则所需的最佳信息。
####实施者规范
提供的此类实现是不可变的，并且是线程安全的。
