java.lang.Objectorg.apache.commons.codec.binary.BinaryCodec
public class BinaryCodec
Translates between byte arrays and strings of "0"s and "1"s. TODO: may want to add more bit vector functions like and/or/xor/nand TODO: also might be good to generate boolean[] from byte[] et. cetera.

java.lang.Object |
decode(java.lang.Object ascii)
Decodes a byte array where each byte represents an ASCII '0' or '1'. |
byte[] |
encode(byte[] raw)
Converts an array of raw binary data into an array of ASCII 0 and 1 characters. |
java.lang.Object |
encode(java.lang.Object raw)
