包路径:java.time.format.DateTimeFormatter
类名称:DateTimeFormatter
方法名:withChronology

DateTimeFormatter.withChronology介绍

[英]Returns a copy of this formatter with a new override chronology.

This returns a formatter with similar state to this formatter but with the override chronology set. By default, a formatter has no override chronology, returning null.

If an override is added, then any date that is printed or parsed will be affected.

When printing, if the Temporal object contains a date then it will be converted to a date in the override chronology. Any time or zone will be retained unless overridden. The converted result will behave in a manner equivalent to an implementation of ChronoLocalDate, ChronoLocalDateTime or ChronoZonedDateTime.

When parsing, the override chronology will be used to interpret the ChronoField into a date unless the formatter directly parses a valid chronology.

This instance is immutable and unaffected by this method call.
[中]返回此格式化程序的副本,其中包含一个新的覆盖年表。
这将返回一个与此格式化程序状态相似但具有覆盖时间序列集的格式化程序。默认情况下,格式化程序没有覆盖时间顺序,返回null。
如果添加了覆盖,则打印或解析的任何日期都将受到影响。
打印时,如果时间对象包含日期,则它将转换为覆盖年表中的日期。任何时间或区域将被保留,除非被覆盖。转换后的结果将以相当于ChronoLocalDate、ChronoLocalDateTime或ChronoZonedDateTime的实现的方式运行。
解析时,除非格式化程序直接解析有效的年表,否则重写年表将用于将ChronoField解释为日期。
此实例是不可变的,不受此方法调用的影响。
