PatternStringParser

public PatternStringParser()

Method Details

parseToPatternInfo

public static PatternStringParser.ParsedPatternInfo parseToPatternInfo(String patternString)

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(String, int) instead.

Parameters:

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

Returns:

The results of the parse.

parseToProperties

public static DecimalFormatProperties parseToProperties(String pattern,
 int ignoreRounding)

Parses a pattern string into a new property bag.

Parameters:

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

ignoreRounding - 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 IGNORE_ROUNDING_ALWAYS, IGNORE_ROUNDING_IF_CURRENCY, or IGNORE_ROUNDING_NEVER.

Returns:

A property bag object.

Throws:

IllegalArgumentException - If there is a syntax error in the pattern string.

parseToProperties

public static DecimalFormatProperties parseToProperties(String pattern)

parseToExistingProperties

public static void parseToExistingProperties(String pattern,
 DecimalFormatProperties properties,
 int ignoreRounding)

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

properties - The property bag object to overwrite.

ignoreRounding - See parseToProperties(String pattern, int ignoreRounding).

Throws:

IllegalArgumentException - If there was a syntax error in the pattern string.
