Converts a pattern between standard notation and localized notation. Localized notation means that instead of using generic placeholders in the pattern, you use the corresponding locale-specific characters instead. For example, in locale fr-FR, the period in the pattern "0.000" means "decimal" in standard notation (as it does in every other locale), but it means "grouping" in localized notation.

A greedy string-substitution strategy is used to substitute locale symbols. If two symbols are ambiguous or have the same prefix, the result is not well-defined.

Locale symbols are not allowed to contain the ASCII quote character.

This method is provided for backwards compatibility and should not be used in any new code.

Parameters

input:String

The pattern to convert.

symbols:DecimalFormatSymbols

The symbols corresponding to the localized pattern.

toLocalized:boolean

true to convert from standard to localized notation; false to convert from localized to standard notation.

Returns:String

The pattern expressed in the other notation.

Determine whether a given roundingIncrement should be ignored for formatting based on the current maxFrac value (maximum fraction digits). For example a roundingIncrement of 0.01 should be ignored if maxFrac is 1, but not if maxFrac is 2 or more. Note that roundingIncrements are rounded up in significance, so a roundingIncrement of 0.006 is treated like 0.01 for this determination, i.e. it should not be ignored if maxFrac is 2 or more (but a roundingIncrement of 0.005 is treated like 0.001 for significance). This test is needed for both NumberPropertyMapper.oldToNew and PatternStringUtils.propertiesToPatternString, but NumberPropertyMapper is package-private so we have it here.

Parameters

roundIncrDec:BigDecimal

The roundingIncrement to be checked. Must be non-null.

maxFrac:int

The current maximum fraction digits value.

Returns:boolean

true if roundIncr should be ignored for formatting.

This method contains the heart of the logic for rendering LDML affix strings. It handles sign-always-shown resolution, whether to use the positive or negative subpattern, permille substitution, and plural forms for CurrencyPluralInfo.

Creates a pattern string from a property bag.

Since pattern strings support only a subset of the functionality available in a property bag, a new property bag created from the string returned by this function may not be the same as the original property bag.

Parameters

properties:DecimalFormatProperties

The property bag to serialize.

Returns:String

A pattern string approximately serializing the property bag.
