枚举 MessagePattern.ApostropheMode

java.lang.Object

java.lang.Enum<MessagePattern.ApostropheMode>

ohos.global.icu.text.MessagePattern.ApostropheMode

所有已实现的接口:

Serializable, Comparable<MessagePattern.ApostropheMode>

封闭类:

MessagePattern

public static enum MessagePattern.ApostropheMode
extends Enum<MessagePattern.ApostropheMode>

Mode for when an apostrophe starts quoted literal text for MessageFormat output. The default is DOUBLE_OPTIONAL unless overridden via ICUConfig (/com/ibm/icu/ICUConfig.properties).

A pair of adjacent apostrophes always results in a single apostrophe in the output, even when the pair is between two single, text-quoting apostrophes.

The following table shows examples of desired MessageFormat.format() output with the pattern strings that yield that output.

Desired output	DOUBLE_OPTIONAL	DOUBLE_REQUIRED
I see {many}	I see '{many}'	(same)
I said {'Wow!'}	I said '{''Wow!''}'	(same)
I don't know	I don't know OR I don''t know	I don''t know

枚举常量

枚举常量	说明
DOUBLE_OPTIONAL	A literal apostrophe is represented by either a single or a double apostrophe pattern character.
DOUBLE_REQUIRED	A literal apostrophe must be represented by a double apostrophe pattern character.

限定符和类型	方法	说明
static MessagePattern.ApostropheMode	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 MessagePattern.ApostropheMode[]	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 (MessagePattern.ApostropheMode c : MessagePattern.ApostropheMode.values()) System.out.println(c);

枚举常量详细资料

DOUBLE_OPTIONAL

public static final MessagePattern.ApostropheMode DOUBLE_OPTIONAL

A literal apostrophe is represented by either a single or a double apostrophe pattern character. Within a MessageFormat pattern, a single apostrophe only starts quoted literal text if it immediately precedes a curly brace {}, or a pipe symbol | if inside a choice format, or a pound symbol # if inside a plural format.

This is the default behavior starting with ICU 4.8.

DOUBLE_REQUIRED

public static final MessagePattern.ApostropheMode DOUBLE_REQUIRED

A literal apostrophe must be represented by a double apostrophe pattern character. A single apostrophe always starts quoted literal text.

This is the behavior of ICU 4.6 and earlier, and of MessageFormat.

方法详细资料

values

public static MessagePattern.ApostropheMode[] 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 (MessagePattern.ApostropheMode c : MessagePattern.ApostropheMode.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 MessagePattern.ApostropheMode 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
