static java.lang.String |
consistentToString(java.math.BigDecimal decimal)
Takes care of the fact that Sun changed the output of BigDecimal.toString() between JDK-1.4 and JDK 5 |
static java.lang.String |
dumpAsHex(byte[] byteBuffer,
int length)
Dumps the given bytes to STDOUT as a hex dump (up to length bytes). |
static byte[] |
escapeEasternUnicodeByteStream(byte[] origBytes,
java.lang.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. |
