Class DecimalFormatSymbols

java.lang.Object
com.ibm.icu.text.DecimalFormatSymbols
All Implemented Interfaces:
Serializable, Cloneable

public class DecimalFormatSymbols extends Object implements Cloneable, Serializable
. This class represents the set of symbols (such as the decimal separator, the grouping separator, and so on) needed by DecimalFormat to format numbers. DecimalFormat creates for itself an instance of DecimalFormatSymbols from its locale data. If you need to change any of these symbols, you can get the DecimalFormatSymbols object from your DecimalFormat and modify it.

    • zeroDigit

      private char zeroDigit
      Character used for zero. This remains only for backward compatibility purposes. The digits array below is now used to actively store the digits.
      See Also:
    • digits

      private char[] digits
      Array of characters used for the digits 0-9 in order.
    • digitStrings

      private String[] digitStrings
      Array of Strings used for the digits 0-9 in order.
    • codePointZero

      private transient int codePointZero
      Dealing with code points is faster than dealing with strings when formatting. Because of this, we maintain a value containing the zero code point that is used whenever digitStrings represents a sequence of ten code points in order.

      If the value stored here is positive, it means that the code point stored in this value corresponds to the digitStrings array, and codePointZero can be used instead of the digitStrings array for the purposes of efficient formatting; if -1, then digitStrings does *not* contain a sequence of code points, and it must be used directly.

      It is assumed that codePointZero always shadows the value in digitStrings. codePointZero should never be set directly; rather, it should be updated only when digitStrings mutates. That is, the flow of information is digitStrings -> codePointZero, not the other way.

    • getPatternForCurrencySpacing

      public String getPatternForCurrencySpacing(int itemType, boolean beforeCurrency)
      Returns the desired currency spacing value. Original values come from ICU's CLDR data based on the locale provided during construction, and can be null. These values govern what and when text is inserted between a currency code/name/symbol and the currency amount when formatting money.

      For more information, see UTS#35 section 5.10.2.

      Parameters:
      itemType - one of CURRENCY_SPC_CURRENCY_MATCH, CURRENCY_SPC_SURROUNDING_MATCH or CURRENCY_SPC_INSERT
      beforeCurrency - true to get the beforeCurrency values, false to get the afterCurrency values.
      Returns:
      the value, or null.
      See Also:
    • setPatternForCurrencySpacing

      public void setPatternForCurrencySpacing(int itemType, boolean beforeCurrency, String pattern)
      Sets the indicated currency spacing pattern or value. See getPatternForCurrencySpacing(int, boolean) for more information.

      Values for currency match and surrounding match must be UnicodeSet patterns. Values for insert can be any string.

      Note: ICU4J does not currently use this information.

      Parameters:
      itemType - one of CURRENCY_SPC_CURRENCY_MATCH, CURRENCY_SPC_SURROUNDING_MATCH or CURRENCY_SPC_INSERT
      beforeCurrency - true if the pattern is for before the currency symbol. false if the pattern is for after it.

    • getLocale

      public final ULocale getLocale(ULocale.Type type)
      Returns the locale that was used to create this object, or null. This may may differ from the locale requested at the time of this object's creation. For example, if an object is created for locale en_US_CALIFORNIA, the actual data may be drawn from en (the actual locale), and en_US may be the most specific locale that exists (the valid locale).

      Note: The actual locale is returned correctly, but the valid locale is not, in most cases.

      Parameters:
      type - type of information requested, either ULocale.VALID_LOCALE or ULocale.ACTUAL_LOCALE.
      Returns:
      the information specified by type, or null if this object was not constructed from locale data.
      See Also:
    • setLocale

      final void setLocale(ULocale valid, ULocale actual)
      Sets information about the locales that were used to create this object. If the object was not constructed from locale data, both arguments should be set to null. Otherwise, neither should be null. The actual locale must be at the same level or less specific than the valid locale. This method is intended for use by factories or other entities that create objects of this class.
      Parameters:
      valid - the most specific locale containing any resource data, or null
      actual - the locale containing data used to construct this object, or null
