Class BinaryCodec

java.lang.Object

tech.gusavila92.apache.commons.codec.binary.BinaryCodec

All Implemented Interfaces:

BinaryDecoder, BinaryEncoder, Decoder, Encoder

public class BinaryCodec
extends java.lang.Object
implements BinaryDecoder, BinaryEncoder

Converts between byte arrays and strings of "0"s and "1"s.

This class is immutable and thread-safe.

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.

Since:

1.3

Method Detail

encode

public byte[] encode(byte[] raw)

Converts an array of raw binary data into an array of ASCII 0 and 1 characters.

Specified by:

encode in interface BinaryEncoder

Parameters:

raw - the raw binary data to convert

Returns:

0 and 1 ASCII character bytes one for each bit of the argument

See Also:

BinaryEncoder.encode(byte[])

encode

public java.lang.Object encode(java.lang.Object raw)
                        throws EncoderException

Converts an array of raw binary data into an array of ASCII 0 and 1 chars.

Specified by:

encode in interface Encoder

Parameters:

raw - the raw binary data to convert

Returns:

0 and 1 ASCII character chars one for each bit of the argument

Throws:

EncoderException - if the argument is not a byte[]

See Also:

Encoder.encode(Object)

decode

public java.lang.Object decode(java.lang.Object ascii)
                        throws DecoderException

Decodes a byte array where each byte represents an ASCII '0' or '1'.

Specified by:

decode in interface Decoder

Parameters:

ascii - each byte represents an ASCII '0' or '1'

Returns:

the raw encoded binary where each bit corresponds to a byte in the byte array argument
