Class Inheritance

extends Object

java.lang.Object
java.lang.ConditionalSpecialCasing

Imports

java.text.BreakIterator, java.util.HashMap, .HashSet, .Iterator, .Locale, sun.text.Normalizer

This is a utility class for String.toLowerCase() and String.toUpperCase(), that handles special casing with conditions. In other words, it handles the mappings with conditions that are defined in Special Casing Properties file.

Note that the unconditional case mappings (including 1:M mappings) are handled in Character.toLower/UpperCase().

Method Detail

isAfterI	back to summary
private static boolean isAfterI(String src, int index) Implements the "After_I" condition Specification The last preceding base character was an uppercase I, and there is no intervening combining character class 230 (ABOVE). Regular Expression: Before C: [I]([{cc!=230}&{cc!=0}])*

isAfterSoftDotted	back to summary
private static boolean isAfterSoftDotted(String src, int index) Implements the "After_Soft_Dotted" condition Specification The last preceding character with combining class of zero before C was Soft_Dotted, and there is no intervening combining character class 230 (ABOVE). Regular Expression: Before C: [{Soft_Dotted==true}]([{cc!=230}&{cc!=0}])*

isBeforeDot	back to summary
private static boolean isBeforeDot(String src, int index) Implements the "Before_Dot" condition Specification C is followed by `U+0307 COMBINING DOT ABOVE`. Any sequence of characters with a combining class that is neither 0 nor 230 may intervene between the current character and the combining dot above. Regular Expression: After C: ([{cc!=230}&{cc!=0}])*[̇]

isCased	back to summary
private static boolean isCased(int ch) Examines whether a character is 'cased'. A character C is defined to be 'cased' if and only if at least one of following are true for C: uppercase==true, or lowercase==true, or general_category==titlecase_letter. The uppercase and lowercase property values are specified in the data file DerivedCoreProperties.txt in the Unicode Character Database.

isConditionMet	back to summary
private static boolean isConditionMet(String src, int index, Locale locale, int condition)

isFinalCased	back to summary
private static boolean isFinalCased(String src, int index, Locale locale) Implements the "Final_Cased" condition Specification Within the closest word boundaries containing C, there is a cased letter before C, and there is no cased letter after C. Regular Expression: Before C: [{cased==true}][{wordBoundary!=true}]* After C: !([{wordBoundary!=true}]*[{cased}])

isMoreAbove	back to summary
private static boolean isMoreAbove(String src, int index) Implements the "More_Above" condition Specification C is followed by one or more characters of combining class 230 (ABOVE) in the combining character sequence. Regular Expression: After C: [{cc!=0}]*[{cc==230}]
