isLetterOrDigit

public static boolean isLetterOrDigit(int c)

Determine whether a (possibly non-BMP) character is a letter or digit.

Parameters:

c - the codepoint of the character to be tested

Returns:

true if this is a number or letter as defined in the XSLT rules for xsl:number pictures.

public UnicodeString format(List<Object> numbers,
 int groupSize,
 String groupSeparator,
 String letterValue,
 String ordinal,
 Numberer numberer)

Format a list of numbers.

Parameters:

numbers - the numbers to be formatted (a sequence of integer values; it may also contain preformatted strings as part of the error recovery fallback)

groupSize - the grouping-size, as in xsl:number

groupSeparator - the grouping-separator, as in xsl:number

letterValue - the letter-value, as in xsl:number

ordinal - the ordinal attribute as in xsl:number

numberer - the Numberer to be used for localization

Returns:

the formatted output string.
