## Typedef Documentation

typedef RuleBasedBreakIterator icu::DictionaryBasedBreakIterator

An obsolete subclass of RuleBasedBreakIterator.

Handling of dictionary- based break iteration has been folded into the base class. This class is deprecated as of ICU 3.6.

Deprecated:
  ICU 3.6

Definition at line 32 of file dbbi.h.

typedef int32_t icu::UFieldResolutionTable[12][8]

Internal:
  Do not use. This API is for internal use only.

Definition at line 44 of file calendar.h.

## Enumeration Type Documentation

enum icu::LanguageCodes

A provisional list of language codes.

For now, this is just a list of languages which the LayoutEngine supports.

Deprecated:
  ICU 54. See icu::LayoutEngine

Definition at line 31 of file LELanguages.h.

enum icu::ScriptCodes

Constants for Unicode script values, generated using ICU4J's `UScript` class.

Deprecated:
  ICU 54. See icu::LayoutEngine

Definition at line 30 of file LEScripts.h.

enum icu::UMatchDegree

Constants returned by `UnicodeMatcher::matches()` indicating the degree of match.

Stable:
  ICU 2.4

Enumerator
U_MISMATCH | Constant returned by `matches()` indicating a mismatch between the text and this matcher. The text contains a character which does not match, or the text does not contain all desired characters for a non-incremental match. Stable: ICU 2.4
U_PARTIAL_MATCH | Constant returned by `matches()` indicating a partial match between the text and this matcher. This value is only returned for incremental match operations. All characters of the text match, but more characters are required for a complete match. Alternatively, for variable-length matchers, all characters of the text match, and if more characters were supplied at limit, they might also match. Stable: ICU 2.4
U_MATCH | Constant returned by `matches()` indicating a complete match between the text and this matcher. For an incremental variable-length match, this value is returned if the given text matches, and it is known that additional characters would not alter the extent of the match. Stable: ICU 2.4

Definition at line 30 of file unimatch.h.

enum icu::URBNFRuleSetTag

Tags for the predefined rulesets.

Stable:
  ICU 2.2

Definition at line 52 of file rbnf.h.
