public class Format extends Object
Format
formats numbers, strings and dates according to the same specification as Visual Basic'sformat()
function. This function is described in more detail here. We have made the following enhancements to this specification:- if the international currency symbol (¤) occurs in a format string, it is translated to the locale's currency symbol.
- the format string "Currency" is translated to the locale's currency format string. Negative currency values appear in parentheses.
- the string "USD" (abbreviation for U.S. Dollars) may occur in a format string.
One format object can be used to format multiple values, thereby amortizing the time required to parse the format string. Example:
double[] values; Format format = new Format("##,##0.###;(##,##0.###);;Nil"); for (int i = 0; i < values.length; i++) { System.out.println("Value #" + i + " is " + format.format(values[i])); }
Still to be implemented:
- String formatting (fill from left/right)
- Use client's timezone for printing times.

Constructs aFormat
in a specific locale, or retrieves one from the cache if one already exists.If the number of entries in the cache exceeds
CacheLimit
, replaces the eldest entry in the cache.- Parameters:

createLocale
public static Format.FormatLocale createLocale(char thousandSeparator, char decimalPlaceholder, String dateSeparator, String timeSeparator, String currencySymbol, String currencyFormat, String[] daysOfWeekShort, String[] daysOfWeekLong, String[] monthsShort, String[] monthsLong, Locale locale)
Create aFormat.FormatLocale
object characterized by the given properties.- Parameters:
thousandSeparator
- the character used to separate thousands in numbers, or ',' by default. For example, 12345 is '12,345 in English, '12.345 in French.decimalPlaceholder
- the character placed between the integer and the fractional part of decimal numbers, or '.' by default. For example, 12.34 is '12.34' in English, '12,34' in French.dateSeparator
- the character placed between the year, month and day of a date such as '12/07/2001', or '/' by default.timeSeparator
- the character placed between the hour, minute and second value of a time such as '1:23:45 AM', or ':' by default.daysOfWeekShort
- Short forms of the days of the week. The array is 1-based, because positionCalendar.SUNDAY
(= 1) must hold Sunday, etc. The array must have 8 elements. For example {"", "Sun", "Mon", ..., "Sat"}.daysOfWeekLong
- Long forms of the days of the week. The array is 1-based, because positionCalendar.SUNDAY
must hold Sunday, etc. The array must have 8 elements. For example {"", "Sunday", ..., "Saturday"}.monthsShort
- Short forms of the months of the year. The array is 0-based, because positionCalendar.JANUARY
(= 0) holds January, etc. For example {"Jan", ..., "Dec", ""}.monthsLong
- Long forms of the months of the year. The array is 0-based, because positionCalendar.JANUARY
(= 0) holds January, etc. For example {"January", ..., "December", ""}.locale
- if this is not null, register that the constructedFormatLocale
is the default forlocale
-

-
getFormatLocale
public static Format.FormatLocale getFormatLocale(Locale locale)
