Constructor Detail

GSMCharset

protected GSMCharset(String canonicalName,
                     String[] aliases,
                     int[] byteToChar,
                     int[] byteToCharEscaped,
                     int[][] charToByte,
                     int[][] charToByteEscaped)

Initializes a new charset with the given canonical name and alias set, and byte-to-char/char-to-byte lookup tables.

Parameters:

canonicalName - the canonical name of this charset

aliases - an array of this charset's aliases, or null if it has no aliases

byteToChar - a byte-to-char conversion table for this charset

byteToCharEscaped - a byte-to-char conversion table for this charset for the escaped characters

charToByte - a char-to-byte conversion table for this charset. It can be generated on-the-fly by calling createInverseLookupTable(byteToChar).

charToByteEscaped - a char-to-byte conversion table for this charset for the escaped characters

Throws:

IllegalCharsetNameException - if the canonical name or any of the aliases are illegal
