- * Mode for when an apostrophe starts quoted literal text for MessageFormat output.
- * The default is DOUBLE_OPTIONAL unless overridden via uconfig.h
- * (UCONFIG_MSGPAT_DEFAULT_APOSTROPHE_MODE).

- * A pair of adjacent apostrophes always results in a single apostrophe in the output,
- * even when the pair is between two single, text-quoting apostrophes.

- * The following table shows examples of desired MessageFormat.format() output
- * with the pattern strings that yield that output.

-/**
- * Parses and represents ICU MessageFormat patterns.
- * Also handles patterns for ChoiceFormat, PluralFormat and SelectFormat.
- * Used in the implementations of those classes as well as in tools
- * for message validation, translation and format conversion.
- * <p>
- * The parser handles all syntax relevant for identifying message arguments.
- * This includes "complex" arguments whose style strings contain
- * nested MessageFormat pattern substrings.
- * For "simple" arguments (with no nested MessageFormat pattern substrings),
- * the argument style is not parsed any further.
- * <p>
- * The parser handles named and numbered message arguments and allows both in one message.
- * <p>
- * Once a pattern has been parsed successfully, iterate through the parsed data
- * with countParts(), getPart() and related methods.
- * <p>
- * The data logically represents a parse tree, but is stored and accessed
- * as a list of "parts" for fast and simple parsing and to minimize object allocations.
- * Arguments and nested messages are best handled via recursion.
- * For every _START "part", MessagePattern.getLimitPartIndex() efficiently returns
- * the index of the corresponding _LIMIT "part".
- * <p>
- * List of "parts":
- * <pre>
- * message = MSG_START (SKIP_SYNTAX | INSERT_CHAR | REPLACE_NUMBER | argument)* MSG_LIMIT
- * argument = noneArg | simpleArg | complexArg
- * complexArg = choiceArg | pluralArg | selectArg
- *
- * noneArg = ARG_START.NONE (ARG_NAME | ARG_NUMBER) ARG_LIMIT.NONE
- * simpleArg = ARG_START.SIMPLE (ARG_NAME | ARG_NUMBER) ARG_TYPE [ARG_STYLE] ARG_LIMIT.SIMPLE
- * choiceArg = ARG_START.CHOICE (ARG_NAME | ARG_NUMBER) choiceStyle ARG_LIMIT.CHOICE
- * pluralArg = ARG_START.PLURAL (ARG_NAME | ARG_NUMBER) pluralStyle ARG_LIMIT.PLURAL
- * selectArg = ARG_START.SELECT (ARG_NAME | ARG_NUMBER) selectStyle ARG_LIMIT.SELECT
- *
- * choiceStyle = ((ARG_INT | ARG_DOUBLE) ARG_SELECTOR message)+
- * pluralStyle = [ARG_INT | ARG_DOUBLE] (ARG_SELECTOR [ARG_INT | ARG_DOUBLE] message)+
- * selectStyle = (ARG_SELECTOR message)+
- * </pre>
- * <ul>
- *   <li>Literal output text is not represented directly by "parts" but accessed
- *       between parts of a message, from one part's getLimit() to the next part's getIndex().
- *   <li><code>ARG_START.CHOICE</code> stands for an ARG_START Part with ArgType CHOICE.
- *   <li>In the choiceStyle, the ARG_SELECTOR has the '<', the '#' or
- *       the less-than-or-equal-to sign (U+2264).
- *   <li>In the pluralStyle, the first, optional numeric Part has the "offset:" value.
- *       The optional numeric Part between each (ARG_SELECTOR, message) pair
- *       is the value of an explicit-number selector like "=2",
- *       otherwise the selector is a non-numeric identifier.
- *   <li>The REPLACE_NUMBER Part can occur only in an immediate sub-message of the pluralStyle.
