## Detailed Description

The CompactDecimalFormat produces abbreviated numbers, suitable for display in environments will limited real estate.

For example, 'Hits: 1.2B' instead of 'Hits: 1,200,000,000'. The format will be appropriate for the given language, such as "1,2 Mrd." for German.

For numbers under 1000 trillion (under 10^15, such as 123,456,789,012,345), the result will be short for supported languages. However, the result may sometimes exceed 7 characters, such as when there are combining marks or thin characters. In such cases, the visual width in fonts should still be short.

By default, there are 3 significant digits. After creation, if more than three significant digits are set (with setMaximumSignificantDigits), or if a fixed number of digits are set (with setMaximumIntegerDigits or setMaximumFractionDigits), then result may be wider.

At this time, parsing is not supported, and will produce a U_UNSUPPORTED_ERROR. Resetting the pattern prefixes or suffixes is not supported; the method calls are ignored.

|  | UnicodeString & | appendTo,
|  | FieldPositionIterator * | posIter,
|  | UErrorCode & | status
| ) |  | const
| virtual

Format an int64 number using base-10 representation.

Currently sets status to U_UNSUPPORTED_ERROR

Parameters

  number | The value to be formatted.
  appendTo | Output parameter to receive result. Result is appended to existing contents.
  posIter | On return, can be used to iterate over positions of fields generated by this format call. Can be NULL.
  status | Output param filled with success/failure status.

Returns
  Reference to 'appendTo' parameter.

|  | UnicodeString & | appendTo,
|  | FieldPositionIterator * | posIter,
|  | UErrorCode & | status
| ) |  | const
| virtual

Format a decimal number.

Currently sets status to U_UNSUPPORTED_ERROR The syntax of the unformatted number is a "numeric string" as defined in the Decimal Arithmetic Specification, available at http://speleotrove.com/decimal

Parameters

  number | The unformatted number, as a string.
  appendTo | Output parameter to receive result. Result is appended to existing contents.
  posIter | On return, can be used to iterate over positions of fields generated by this format call. Can be NULL.
  status | Output param filled with success/failure status.

Returns
  Reference to 'appendTo' parameter.

|  | UnicodeString & | appendTo,
|  | FieldPositionIterator * | posIter,
|  | UErrorCode & | status
| ) |  | const
| virtual

Format a decimal number.

Currently sets status to U_UNSUPPORTED_ERROR The number is a DigitList wrapper onto a floating point decimal number. The default implementation in NumberFormat converts the decimal number to a double and formats that.

Parameters

  number | The number, a DigitList format Decimal Floating Point.
  appendTo | Output parameter to receive result. Result is appended to existing contents.
  posIter | On return, can be used to iterate over positions of fields generated by this format call.
  status | Output param filled with success/failure status.

Returns
  Reference to 'appendTo' parameter.

|  | UnicodeString & | appendTo,

| ) |  | const
| virtual

Format a decimal number.

Currently sets status to U_UNSUPPORTED_ERROR. The number is a DigitList wrapper onto a floating point decimal number. The default implementation in NumberFormat converts the decimal number to a double and formats that.

Parameters

  number | The number, a DigitList format Decimal Floating Point.
  appendTo | Output parameter to receive result. Result is appended to existing contents.
  pos | On input: an alignment field, if desired. On output: the offsets of the alignment field.
  status | Output param filled with success/failure status.

Returns
  Reference to 'appendTo' parameter.

virtual UClassID icu::CompactDecimalFormat::getDynamicClassID | ( |  | ) | const
| virtual

Returns a unique class ID POLYMORPHICALLY.

Pure virtual override. This method is to implement a simple version of RTTI, since not all C++ compilers support genuine RTTI. Polymorphic operator==() and clone() methods call this method.

Returns
  The class ID for this object. All objects of a given class have the same class ID. Objects of other classes have different class IDs.

Stable:
  ICU 51

Reimplemented from icu::DecimalFormat.

static UClassID icu::CompactDecimalFormat::getStaticClassID | ( |  | ) |
| static

Return the class ID for this class.

This is useful only for comparing to a return value from getDynamicClassID(). For example:

    .      Base* polymorphic_pointer = createPolymorphicObject();
    .      if (polymorphic_pointer->getDynamicClassID() ==
    .          Derived::getStaticClassID()) ...

Returns
  The class ID for all objects of this class.

CompactDecimalFormat& icu::CompactDecimalFormat::operator= | ( | const CompactDecimalFormat & | rhs | ) |

Assignment operator.

Parameters

  rhs | the DecimalFormat object to be copied.

Stable:
  ICU 51

virtual UBool icu::CompactDecimalFormat::operator== | ( | const Format & | other | ) | const
| virtual

Return TRUE if the given Format objects are semantically equal.

Objects of different subclasses are considered unequal.

Parameters

  other | the object to be compared with.

Returns
  TRUE if the given Format objects are semantically equal.

virtual void icu::CompactDecimalFormat::parse | ( | const UnicodeString & | text,
|  | Formattable & | result,
|  | ParsePosition & | parsePosition

CompactDecimalFormat does not support parsing.

This implementation does nothing.

Parameters

  text | Unused.
  result | Does not change.
  parsePosition | Does not change.

virtual void icu::CompactDecimalFormat::parse | ( | const UnicodeString & | text,
|  | Formattable & | result,
|  | UErrorCode & | status
| ) |  | const

CompactDecimalFormat does not support parsing.

This implementation sets status to U_UNSUPPORTED_ERROR

Parameters

  text | Unused.
  result | Does not change.
  status | Always set to U_UNSUPPORTED_ERROR.

virtual CurrencyAmount* icu::CompactDecimalFormat::parseCurrency | ( | const UnicodeString & | text,
|  | ParsePosition & | pos
| ) |  | const
| virtual

Parses text from the given string as a currency amount.

Unlike the parse() method, this method will attempt to parse a generic currency name, searching for a match of this object's locale's currency display names, or for a 3-letter ISO currency code. This method will fail if this format is not a currency format, that is, if it does not contain the currency pattern symbol (U+00A4) in its prefix or suffix. This implementation always returns NULL.

Parameters

  text | the string to parse
  pos | input-output position; on input, the position within text to match; must have 0 <= pos.getIndex() < text.length(); on output, the position after the last matched character. If the parse fails, the position in unchanged upon output.

Returns
  if parse succeeds, a pointer to a newly-created CurrencyAmount object (owned by the caller) containing information about the parsed currency; if parse fails, this is NULL.
