• Method Detail

  • toAsciiBytes

    public static byte[] toAsciiBytes(char[] chars,
                      int offset,
                      int length)

    Returns a new byte array containing the bytes corresponding to the given characters, encoded in US-ASCII. Unrepresentable characters are replaced by (byte) '?'.

  • toIsoLatin1Bytes

    public static byte[] toIsoLatin1Bytes(char[] chars,
                          int offset,
                          int length)

    Returns a new byte array containing the bytes corresponding to the given characters, encoded in ISO-8859-1. Unrepresentable characters are replaced by (byte) '?'.

  • toUtf8Bytes

    public static byte[] toUtf8Bytes(char[] chars,
                     int offset,
                     int length)

    Returns a new byte array containing the bytes corresponding to the given characters, encoded in UTF-8. All characters are representable in UTF-8.

  • toBigEndianUtf16Bytes

    public static byte[] toBigEndianUtf16Bytes(char[] chars,
                               int offset,
                               int length)

    Returns a new byte array containing the bytes corresponding to the given characters, encoded in UTF-16BE. All characters are representable in UTF-16BE.

  • asciiBytesToChars

    public static void asciiBytesToChars(byte[] bytes,
                         int offset,
                         int length,
                         char[] chars)

    Decodes the given US-ASCII bytes into the given char[]. Equivalent to but faster than: for (int i = 0; i < count; ++i) { char ch = (char) (data[start++] & 0xff); value[i] = (ch <= 0x7f) ? ch : replacement_char; }

  • isoLatin1BytesToChars

    public static void isoLatin1BytesToChars(byte[] bytes,
                             int offset,
                             int length,
                             char[] chars)

    Decodes the given ISO-8859-1 bytes into the given char[]. Equivalent to but faster than: for (int i = 0; i < count; ++i) { value[i] = (char) (data[start++] & 0xff); }
