| ↳ | android.icu.text.NumberingSystem |
NumberingSystem is the base class for all number
systems. This class provides the interface for setting different numbering
system types, whether it be a simple alternate digit system such as
Thai digits or Devanagari digits, or an algorithmic numbering system such
as Hebrew numbering or Chinese numbering.

NumberingSystem ()
Default constructor. Returns a numbering system that uses the Western decimal digits 0 through 9.
String[] getAvailableNames ()
Returns a string array containing a list of the names of numbering systems currently known to ICU.
| Returns | |
|---|---|
String[] |
|
String getDescription ()
Returns the description string of the current numbering system. The description string describes the characteristics of the numbering system. For numeric systems, this string contains the digits used by the numbering system, in order, starting from zero. For algorithmic numbering systems, the string contains the name of the RBNF ruleset in the locale's NumberingSystemRules section that will be used to format numbers using this numbering system.
| Returns | |
|---|---|
String |

NumberingSystem getInstance (ULocale locale)
Returns the default numbering system for the specified ULocale.
| Parameters | |
|---|---|
locale |
ULocale

| Returns | |

NumberingSystem getInstance (Locale inLocale)
Returns the default numbering system for the specified locale.
| Parameters | |
|---|---|
inLocale |
Locale
|
| Returns | |
|---|---|
NumberingSystem |
|
NumberingSystem getInstance ()
Returns the default numbering system for the default FORMAT locale.
| Returns | |

NumberingSystem getInstance (int radix_in, boolean isAlgorithmic_in, String desc_in)
Factory method for creating a numbering system.
| Parameters | |
|---|---|
radix_in |
int:
The radix for this numbering system. ICU currently
supports only numbering systems whose radix is 10. |
isAlgorithmic_in |
boolean:
Specifies whether the numbering system is algorithmic
(true) or numeric (false). |
desc_in |
String:
String used to describe the characteristics of the numbering
system. For numeric systems, this string contains the digits used by the
numbering system, in order, starting from zero. For algorithmic numbering
systems, the string contains the name of the RBNF ruleset in the locale's
NumberingSystemRules section that will be used to format numbers using
this numbering system.

| Returns | |
|---|---|
NumberingSystem |
|
NumberingSystem getInstanceByName (String name)
Returns a numbering system from one of the predefined numbering systems known to ICU. Numbering system names are based on the numbering systems defined in CLDR. To get a list of available numbering systems, use the getAvailableNames method.
| Parameters | |
|---|---|
name |
String:
The name of the desired numbering system. Numbering system
names often correspond with the name of the script they are associated
with. For example, "thai" for Thai digits, "hebr" for Hebrew numerals.
|
| Returns | |
|---|---|
NumberingSystem |
|
String getName ()
Returns the string representing the name of the numbering system.
| Returns | |
|---|---|
String |
|
int getRadix ()
Returns the radix of the current numbering system.
| Returns | |
|---|---|
int |
|
boolean isAlgorithmic ()
Returns the numbering system's algorithmic status. If true, the numbering system is algorithmic and uses an RBNF formatter to format numerals. If false, the numbering system is numeric and uses a fixed set of digits.
| Returns | |
|---|---|
boolean |
|
boolean isValidDigitString (String str)
Convenience method to determine if a given digit string is valid for use as a descriptor of a numeric ( non-algorithmic ) numbering system. In order for a digit string to be valid, it must meet the following criteria: 1. Digits must be in Unicode's basic multilingual plane.

str |
