| Method Summary | |
| public static String | consistentToString(BigDecimal decimal)
| | final public static String | dumpAsHex(byte[] byteBuffer, int length)
Dumps the given bytes to STDOUT as a hex dump (up to length bytes). | | public static byte[] | escapeEasternUnicodeByteStream(byte[] origBytes, String origString, int offset, int length)
Unfortunately, SJIS has 0x5c as a high byte in some of its double-byte
characters, so we need to escape it.
Parameters:
origBytes - the original bytes in SJIS format
Parameters:
origString - the string that had .getBytes() called on it
Parameters:
offset - where to start converting from
Parameters:
length - how many characters to convert. | | public static char | firstNonWsCharUc(String searchIn)
