bytes - a byte array to format

Returns:

the contents of the byte array as a hex-formatted string

format

public static String format(byte[] bytes,
            int limit)

Returns a string constructed with the contents of the byte array converted to hex format. The entire string is enclosed in square brackets, and the octets are separated by a single space character.

Parameters:

bytes - a byte array to format

limit - the maximum number of bytes to format, or 0 meaning unlimited

Returns:

the contents of the byte array as a hex-formatted string

format

public static String format(ByteBuffer buf)

Returns a string constructed with the contents of the ByteBuffer converted to hex format. The entire string is enclosed in square brackets, and the octets are separated by a single space character.
