枚举 SearchIterator.ElementComparisonType

java.lang.Object

java.lang.Enum<SearchIterator.ElementComparisonType>

ohos.global.icu.text.SearchIterator.ElementComparisonType

所有已实现的接口:

Serializable, Comparable<SearchIterator.ElementComparisonType>

封闭类:

SearchIterator

public static enum SearchIterator.ElementComparisonType
extends Enum<SearchIterator.ElementComparisonType>

Option to control how collation elements are compared. The default value will be STANDARD_ELEMENT_COMPARISON.

PATTERN_BASE_WEIGHT_IS_WILDCARD supports "asymmetric search" as described in UTS #10 Unicode Collation Algorithm, while ANY_BASE_WEIGHT_IS_WILDCARD supports a related option in which "unmarked" characters in either the pattern or the searched text are treated as wildcards that match marked or unmarked versions of the same character.

枚举常量概要

枚举常量

枚举常量	说明
ANY_BASE_WEIGHT_IS_WILDCARD	Collation element comparison is modified to effectively provide behavior between the specified strength and strength - 1.
PATTERN_BASE_WEIGHT_IS_WILDCARD	Collation element comparison is modified to effectively provide behavior between the specified strength and strength - 1.
STANDARD_ELEMENT_COMPARISON	Standard collation element comparison at the specified collator strength.

方法概要

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

枚举常量详细资料

STANDARD_ELEMENT_COMPARISON

public static final SearchIterator.ElementComparisonType STANDARD_ELEMENT_COMPARISON

Standard collation element comparison at the specified collator strength.

PATTERN_BASE_WEIGHT_IS_WILDCARD

public static final SearchIterator.ElementComparisonType PATTERN_BASE_WEIGHT_IS_WILDCARD

Collation element comparison is modified to effectively provide behavior between the specified strength and strength - 1.

Collation elements in the pattern that have the base weight for the specified strength are treated as "wildcards" that match an element with any other weight at that collation level in the searched text. For example, with a secondary-strength English collator, a plain 'e' in the pattern will match a plain e or an e with any diacritic in the searched text, but an e with diacritic in the pattern will only match an e with the same diacritic in the searched text.

ANY_BASE_WEIGHT_IS_WILDCARD

public static final SearchIterator.ElementComparisonType ANY_BASE_WEIGHT_IS_WILDCARD

Collation element comparison is modified to effectively provide behavior between the specified strength and strength - 1.

Collation elements in either the pattern or the searched text that have the base weight for the specified strength are treated as "wildcards" that match an element with any other weight at that collation level. For example, with a secondary-strength English collator, a plain 'e' in the pattern will match a plain e or an e with any diacritic in the searched text, but an e with diacritic in the pattern will only match an e with the same diacritic or a plain e in the searched text.

方法详细资料

values

public static SearchIterator.ElementComparisonType[] 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 (SearchIterator.ElementComparisonType c : SearchIterator.ElementComparisonType.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 SearchIterator.ElementComparisonType 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
