TemporalQueries介绍

[英]Common implementations of TemporalQuery.

This class provides common implementations of TemporalQuery. These queries are primarily used as optimizations, allowing the internals of other objects to be extracted effectively. Note that application code can also use the from(TemporalAccessor) method on most temporal objects as a method reference matching the query interface, such as LocalDate::from and ZoneId::from.

There are two equivalent ways of using a TemporalQuery. The first is to invoke the method on the interface directly. The second is to use TemporalAccessor#query(TemporalQuery):

// these two lines are equivalent, but the second approach is recommended 
dateTime = query.queryFrom(dateTime); 
dateTime = dateTime.query(query);

It is recommended to use the second approach, query(TemporalQuery), as it is a lot clearer to read in code.

Specification for implementors

This is a thread-safe utility class. All returned adjusters are immutable and thread-safe.
[中]临时查询的常见实现。
此类提供了临时查询的常见实现。这些查询主要用于优化，允许有效地提取其他对象的内部。请注意，应用程序代码还可以在大多数时态对象上使用from（TemporalAccessor）方法作为与查询接口匹配的方法引用，例如LocalDate:：from和ZoneId:：from。
使用临时查询有两种等效的方法。第一种方法是直接调用接口上的方法。第二种是使用TemporalAccessor#query（TemporalQuery）：

// these two lines are equivalent, but the second approach is recommended 
dateTime = query.queryFrom(dateTime); 
dateTime = dateTime.query(query);

建议使用第二种方法，即查询（临时查询），因为在代码中阅读要清晰得多。
####实施者规范
这是一个线程安全实用程序类。所有返回的调节器都是不可变的，线程安全。
