public static enum SearchIterator.ElementComparisonType extends Enum<SearchIterator.ElementComparisonType>
Option to control how collation elements are compared. The default value will beSTANDARD_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.

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.

values
public static SearchIterator.ElementComparisonType[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (SearchIterator.ElementComparisonType c : SearchIterator.ElementComparisonType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static SearchIterator.ElementComparisonType valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified nameNullPointerException
- if the argument is null
