枚举常量详细资料

MSG_START

public static final MessagePattern.Part.Type MSG_START

Start of a message pattern (main or nested). The length is 0 for the top-level message and for a choice argument sub-message, otherwise 1 for the '{'. The value indicates the nesting level, starting with 0 for the main message.

There is always a later MSG_LIMIT part.

MSG_LIMIT

public static final MessagePattern.Part.Type MSG_LIMIT

End of a message pattern (main or nested). The length is 0 for the top-level message and the last sub-message of a choice argument, otherwise 1 for the '}' or (in a choice argument style) the '|'. The value indicates the nesting level, starting with 0 for the main message.

SKIP_SYNTAX

public static final MessagePattern.Part.Type SKIP_SYNTAX

Indicates a substring of the pattern string which is to be skipped when formatting. For example, an apostrophe that begins or ends quoted text would be indicated with such a part. The value is undefined and currently always 0.

INSERT_CHAR

public static final MessagePattern.Part.Type INSERT_CHAR

Indicates that a syntax character needs to be inserted for auto-quoting. The length is 0. The value is the character code of the insertion character. (U+0027=APOSTROPHE)

REPLACE_NUMBER

public static final MessagePattern.Part.Type REPLACE_NUMBER

Indicates a syntactic (non-escaped) # symbol in a plural variant. When formatting, replace this part's substring with the (value-offset) for the plural argument value. The value is undefined and currently always 0.

ARG_START

public static final MessagePattern.Part.Type ARG_START

Start of an argument. The length is 1 for the '{'. The value is the ordinal value of the ArgType. Use getArgType().

This part is followed by either an ARG_NUMBER or ARG_NAME, followed by optional argument sub-parts (see ArgType constants) and finally an ARG_LIMIT part.

ARG_LIMIT

public static final MessagePattern.Part.Type ARG_LIMIT

End of an argument. The length is 1 for the '}'. The value is the ordinal value of the ArgType. Use getArgType().

ARG_NUMBER

public static final MessagePattern.Part.Type ARG_NUMBER

The argument number, provided by the value.

ARG_NAME

public static final MessagePattern.Part.Type ARG_NAME

The argument name. The value is undefined and currently always 0.

ARG_TYPE

public static final MessagePattern.Part.Type ARG_TYPE

The argument type. The value is undefined and currently always 0.

ARG_STYLE

public static final MessagePattern.Part.Type ARG_STYLE

The argument style text. The value is undefined and currently always 0.

ARG_SELECTOR

public static final MessagePattern.Part.Type ARG_SELECTOR

A selector substring in a "complex" argument style. The value is undefined and currently always 0.

ARG_INT

public static final MessagePattern.Part.Type ARG_INT

An integer value, for example the offset or an explicit selector value in a PluralFormat style. The part value is the integer value.

ARG_DOUBLE

public static final MessagePattern.Part.Type ARG_DOUBLE

A numeric value, for example the offset or an explicit selector value in a PluralFormat style. The part value is an index into an internal array of numeric values; use getNumericValue().

方法详细资料

values

public static MessagePattern.Part.Type[] 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.Part.Type c : MessagePattern.Part.Type.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.Part.Type 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

hasNumericValue

public boolean hasNumericValue()

Indicates whether this part has a numeric value. If so, then that numeric value can be retrieved via MessagePattern#getNumericValue(Part).

返回:

true if this part has a numeric value.
