Method Detail

decodeHex

public static byte[] decodeHex(char[] data)
                        throws DecoderException

Deprecated.

Converts an array of characters representing hexidecimal values into an array of bytes of those same values. The returned array will be half the length of the passed array, as it takes two characters to represent any given byte. An exception is thrown if the passed char array has an odd number of elements.

Parameters:

data - An array of characters containing hexidecimal digits

Returns:

A byte array containing binary data decoded from the supplied char array.

Throws:

DecoderException - Thrown if an odd number or illegal of characters is supplied

encodeHex

public static char[] encodeHex(byte[] data)

Deprecated.

Converts an array of bytes into an array of characters representing the hexidecimal values of each byte in order. The returned array will be double the length of the passed array, as it takes two characters to represent any given byte.

Parameters:

data - a byte[] to convert to Hex characters

Returns:

A char[] containing hexidecimal characters

decode

public byte[] decode(byte[] array)
              throws DecoderException

Deprecated.

Converts an array of character bytes representing hexidecimal values into an array of bytes of those same values. The returned array will be half the length of the passed array, as it takes two characters to represent any given byte. An exception is thrown if the passed char array has an odd number of elements.

Specified by:

decode in interface BinaryDecoder

Parameters:

array - An array of character bytes containing hexidecimal digits

Returns:

A byte array containing binary data decoded from the supplied byte array (representing characters).

Throws:

DecoderException - Thrown if an odd number of characters is supplied to this function

See Also:

decodeHex(char[])

decode

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

Deprecated.

Converts a String or an array of character bytes representing hexidecimal values into an array of bytes of those same values. The returned array will be half the length of the passed String or array, as it takes two characters to represent any given byte. An exception is thrown if the passed char array has an odd number of elements.

Specified by:

decode in interface Decoder

Parameters:

object - A String or, an array of character bytes containing hexidecimal digits

Returns:

A byte array containing binary data decoded from the supplied byte array (representing characters).

Throws:

DecoderException - Thrown if an odd number of characters is supplied to this function or the object is not a String or char[]

See Also:

decodeHex(char[])

encode

public byte[] encode(byte[] array)

Deprecated.

Converts an array of bytes into an array of bytes for the characters representing the hexidecimal values of each byte in order. The returned array will be double the length of the passed array, as it takes two characters to represent any given byte.

Specified by:

encode in interface BinaryEncoder

Parameters:

array - a byte[] to convert to Hex characters

Returns:

A byte[] containing the bytes of the hexidecimal characters

See Also:

encodeHex(byte[])

encode

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

Deprecated.

Converts a String or an array of bytes into an array of characters representing the hexidecimal values of each byte in order. The returned array will be double the length of the passed String or array, as it takes two characters to represent any given byte.

Specified by:

encode in interface Encoder

Parameters:

object - a String, or byte[] to convert to Hex characters

Returns:

A char[] containing hexidecimal characters

Throws:

EncoderException - Thrown if the given object is not a String or byte[]

encodeHex(byte[])
