Field Detail

MAX_STRING_LENGTH

public static final int MAX_STRING_LENGTH

For string case mappings, a single character (a code point) is mapped either to itself (in which case in-place mapping functions do nothing), or to another single code point, or to a string. Aside from the string contents, these are indicated with a single int value as follows: Mapping to self: Negative values (~self instead of -self to support U+0000) Mapping to another code point: Positive values >MAX_STRING_LENGTH Mapping to a string: The string length (0..MAX_STRING_LENGTH) is returned. Note that the string result may indeed have zero length.

Method Detail

addPropertyStarts

public final void addPropertyStarts(UnicodeSet set)

tolower

public final int tolower(int c)

toupper

public final int toupper(int c)

totitle

public final int totitle(int c)

addCaseClosure

public final void addCaseClosure(int c,
                                 UnicodeSet set)

Adds all simple case mappings and the full case folding for c to sa, and also adds special case closure mappings. c itself is not added. For example, the mappings - for s include long s - for sharp s include ss - for k include the Kelvin sign

addSimpleCaseClosure

public final void addSimpleCaseClosure(int c,
                                       UnicodeSet set)

addStringCaseClosure

public final boolean addStringCaseClosure(String s,
                                          UnicodeSet set)

Maps the string to single code points and adds the associated case closure mappings. The string is mapped to code points if it is their full case folding string. In other words, this performs a reverse full case folding and then adds the case closure items of the resulting code points. If the string is found and its closure applied, then the string itself is added as well as part of its code points' closure.

Returns:

true if the string was found

getType

public final int getType(int c)

Returns:

NONE, LOWER, UPPER, TITLE

getTypeOrIgnorable

public final int getTypeOrIgnorable(int c)

Returns:

like getType() but also sets IGNORABLE if c is case-ignorable

getDotType

public final int getDotType(int c)

Returns:

NO_DOT, SOFT_DOTTED, ABOVE, OTHER_ACCENT

isSoftDotted

public final boolean isSoftDotted(int c)

isCaseSensitive

public final boolean isCaseSensitive(int c)

getCaseLocale

public static final int getCaseLocale(Locale locale)

getCaseLocale

public static final int getCaseLocale(ULocale locale)

toFullLower

public final int toFullLower(int c,
                             UCaseProps.ContextIterator iter,
                             Appendable out,
                             int caseLocale)

Get the full lowercase mapping for c.

Parameters:

c - Character to be mapped.

iter - Character iterator, used for context-sensitive mappings. See ContextIterator for details. If iter==null then a context-independent result is returned.

out - If the mapping result is a string, then it is appended to out.

caseLocale - Case locale value from ucase_getCaseLocale().

Returns:

Output code point or string length, see MAX_STRING_LENGTH.
