Class DecimalNumberFormatter
java.lang.Object
com.novell.xsl.number.DecimalNumberFormatter
- All Implemented Interfaces:
- NumberFormatter
- public class DecimalNumberFormatter
- extends Object
- implements NumberFormatter
A class that formats integers into a decimal representation. This class
corresponds to xsl:number
format tokens such as 1
,
01
, etc.
Decimal number formats are characterized by their use of ten decimal digits
(characters with a Unicode category of Nd) with sequential Unicode decimal
digit values. In Java terms, for each of the decimal digits,
java.lang.Character.isDigit
would evaluate to
true
and java.lang.Character.digit
would return
the Unicode decimal digit value.

DecimalNumberFormatter
public DecimalNumberFormatter(char firstDigit,
int minDigits)
- Constructs a decimal number formatter that uses the specified characters
as digits.
For example, the number formatter created by
new DecimalNumberFormatter('0', 1)
corresponds to the
format token 1
. It generates the sequence
1 2 3 ... 9 10 11 12 ....
- Parameters:
firstDigit
- the first digit to be used, such as '0'
minDigits
- the minimum number of digits; formatted numbers will
have extra firstDigit characters
prepended if necessary
- Throws:
IllegalArgumentException
- if the first digit is not a Unicode decimal digit
whose decimal digit value is zero (that is,
java.lang.Character.digit(
firstDigit,
10)
is not equal to zero) or the minimum
number of digits is less than zero
format
public String format(int value)
throws IllegalArgumentException
