Parses a pattern string into an existing property bag. All properties that can be encoded into a pattern string will be overwritten with either their default value or with the value coming from the pattern string. Properties that cannot be encoded into a pattern string, such as rounding mode, are not modified.

Parameters

pattern:String

The pattern string, like "#,##0.00"

properties:DecimalFormatProperties

The property bag object to overwrite.

ignoreRounding:int

See parseToProperties(String pattern, int ignoreRounding).

Exceptions

IllegalArgumentException:

If there was a syntax error in the pattern string.

Runs the recursive descent parser on the given pattern string, returning a data structure with raw information about the pattern string.

To obtain a more useful form of the data, consider using parseToProperties instead.

Parameters

patternString:String

The LDML decimal format pattern (Excel-style pattern) to parse.

Returns:PatternStringParser.ParsedPatternInfo

The results of the parse.

Parses a pattern string into a new property bag.

Parameters

pattern:String

The pattern string, like "#,##0.00"

ignoreRounding:int

Whether to leave out rounding information (minFrac, maxFrac, and rounding increment) when parsing the pattern. This may be desirable if a custom rounding mode, such as CurrencyUsage, is to be used instead. One of PatternStringParser#IGNORE_ROUNDING_ALWAYS, PatternStringParser#IGNORE_ROUNDING_IF_CURRENCY, or PatternStringParser#IGNORE_ROUNDING_NEVER.

Returns:DecimalFormatProperties

A property bag object.

Exceptions

IllegalArgumentException:

If there is a syntax error in the pattern string.
