枚举 ZoneOffsetTransitionRule.TimeDefinition

java.lang.Object

java.lang.Enum<ZoneOffsetTransitionRule.TimeDefinition>

java.time.zone.ZoneOffsetTransitionRule.TimeDefinition

所有已实现的接口:

Serializable, Comparable<ZoneOffsetTransitionRule.TimeDefinition>

封闭类:

ZoneOffsetTransitionRule

public static enum ZoneOffsetTransitionRule.TimeDefinition
extends Enum<ZoneOffsetTransitionRule.TimeDefinition>

A definition of the way a local time can be converted to the actual transition date-time.

Time zone rules are expressed in one of three ways:

• Relative to UTC
• Relative to the standard offset in force
• Relative to the wall offset (what you would see on a clock on the wall)

枚举常量概要

枚举常量

枚举常量	说明
STANDARD	The local date-time is expressed in terms of the standard offset.
UTC	The local date-time is expressed in terms of the UTC offset.
WALL	The local date-time is expressed in terms of the wall offset.

方法概要

限定符和类型	方法	说明
LocalDateTime	createDateTime(LocalDateTime dateTime, ZoneOffset standardOffset, ZoneOffset wallOffset)	Converts the specified local date-time to the local date-time actually seen on a wall clock.
static ZoneOffsetTransitionRule.TimeDefinition	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static ZoneOffsetTransitionRule.TimeDefinition[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (ZoneOffsetTransitionRule.TimeDefinition c : ZoneOffsetTransitionRule.TimeDefinition.values()) System.out.println(c);

枚举常量详细资料

UTC

public static final ZoneOffsetTransitionRule.TimeDefinition UTC

The local date-time is expressed in terms of the UTC offset.

WALL

public static final ZoneOffsetTransitionRule.TimeDefinition WALL

The local date-time is expressed in terms of the wall offset.

STANDARD

public static final ZoneOffsetTransitionRule.TimeDefinition STANDARD

The local date-time is expressed in terms of the standard offset.

方法详细资料

values

public static ZoneOffsetTransitionRule.TimeDefinition[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (ZoneOffsetTransitionRule.TimeDefinition c : ZoneOffsetTransitionRule.TimeDefinition.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static ZoneOffsetTransitionRule.TimeDefinition valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

createDateTime

public LocalDateTime createDateTime(LocalDateTime dateTime,
                                    ZoneOffset standardOffset,
                                    ZoneOffset wallOffset)

Converts the specified local date-time to the local date-time actually seen on a wall clock.

This method converts using the type of this enum. The output is defined relative to the 'before' offset of the transition.

The UTC type uses the UTC offset. The STANDARD type uses the standard offset. The WALL type returns the input date-time. The result is intended for use with the wall-offset.

参数:

dateTime - the local date-time, not null

standardOffset - the standard offset, not null

wallOffset - the wall offset, not null

返回:

the date-time relative to the wall/before offset, not null
