Enum SearchIterator.ElementComparisonType

java.lang.Object

java.lang.Enum<SearchIterator.ElementComparisonType>

org.graalvm.shadowed.com.ibm.icu.text.SearchIterator.ElementComparisonType

All Implemented Interfaces:

Serializable, Comparable<SearchIterator.ElementComparisonType>, java.lang.constant.Constable

Enclosing class:

SearchIterator

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

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

Enum Constant Summary

Enum Constants

Enum Constant and Description
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.

Method Summary

Modifier and Type	Method and Description

Enum Constant Detail

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.
