Temporal.plus介绍

[英]Returns an object of the same type as this object with the specified period added.

This method returns a new object based on this one with the specified period added. For example, on a LocalDate, this could be used to add a number of years, months or days. The returned object will have the same observable type as this object.

In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st January, then adding one month would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.

If the implementation represents a date-time that has boundaries, such as LocalTime, then the permitted units must include the boundary unit, but no multiples of the boundary unit. For example, LocalTime must accept DAYS but not WEEKS or MONTHS.

Specification for implementors

Implementations must check and handle all units defined in ChronoUnit. If the unit is supported, then the addition must be performed. If unsupported, then a DateTimeException must be thrown.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.addTo(Temporal, long)passing this as the first argument.

Implementations must not alter either this object or the specified temporal object. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable implementations.
[中]返回与此对象类型相同且添加了指定句点的对象。
此方法返回基于此对象的新对象，并添加指定的句点。例如，在LocalDate上，这可以用于添加若干年、月或日。返回的对象将具有与此对象相同的可观察类型。
在某些情况下，更改字段没有完全定义。例如，如果目标对象是代表1月31日的日期，那么添加一个月就不清楚了。在这种情况下，字段负责解决结果。通常，它会选择上一个有效日期，在本例中是2月的最后一个有效日期。
如果实现表示有边界的日期时间，例如LocalTime，那么允许的单位必须包括边界单位，但不能是边界单位的倍数。例如，LocalTime必须接受天，而不是周或月。
####实施者规范
实现必须检查并处理IT中定义的所有单元。如果支持该装置，则必须进行添加。如果不支持，则必须抛出DateTimeException。
如果该单元不是ChronoUnit，则通过调用TemporalUnit获得该方法的结果。addTo（暂时的，长的）将此作为第一个参数传递。
实现不能更改此对象或指定的时态对象。相反，必须返回经调整的原件副本。这为不可变和可变的实现提供了等效的、安全的行为。
