static byte[] | concat(byte[] b1, byte[] b2)- Concatenate two byte arrays into one.
|
static String | formatInt(int i, int radix, int len)- Format an integer into the specified radix, zero-filled.
|
static String | hexDump(byte[] buf)- See
hexDump(byte[],int,int,String).
|
static String | hexDump(byte[] buf, int off, int len)- See
hexDump(byte[],int,int,String).
|
static String | hexDump(byte[] buf, int off, int len, String prefix)- Create a representation of the given byte array similar to the
output of
`hexdump -C', which is
OFFSET SIXTEEN-BYTES-IN-HEX PRINTABLE-BYTES
The printable bytes show up as-is if they are printable and
not a newline character, otherwise showing as '.'.

|
static String | toHexString(byte[] buf)- See
toHexString(byte[],int,int).
|
static String | toHexString(byte[] buf, char sep)- See
toHexString(byte[],int,int,char).
|
static String | toHexString(byte[] buf, int off, int len)- Convert a byte array to a hexadecimal string, as though it were a
big-endian arbitrarily-sized integer.
|
static String | toHexString(byte[] buf, int off, int len, char sep)- Convert a byte array to a hexadecimal string, separating octets
with the given character.
|
static byte[] | trim(byte[] buffer, int len)- See
trim(byte[],int,int).
|
static byte[] | trim(byte[] buffer, int off, int len)- Returns a portion of a byte array, possibly zero-filled.
|
static byte[] | trim(BigInteger bi)- Returns the byte array representation of the given big integer with
the leading zero byte (if any) trimmed off.
