Field Detail

hexval
final protected static byte hexval(Code)
	The nibbles' hexadecimal values. A nibble is a half byte.

Method Detail

decodeNibble
protected static byte decodeNibble(char c)(Code)
	Decodes a nibble. Parameters: c - A character in the range '0'-'9' or 'A'-'F'. Lowercase is not supported here. The decoded nibble in the range 0-15 throws: IllegalArgumentException - if c is not apermitted character

hexDecode
public static byte[] hexDecode(String s)(Code)
	Decodes the hexadecimal representation of a sequence of bytes into a byte array. Each character in the string represents a nibble (half byte) and must be one of the characters '0'-'9', 'A'-'F' or 'a'-'f'. Parameters: s - The string to be decoded The bytes

hexDecodeObject
public static Object hexDecodeObject(String bytes)(Code)

hexEncode

public static String hexEncode(String s)(Code)

Converts a string into its hexadecimal notation.

FIXME: If this method is called frequently, it should directly implement the algorithm in the called method in order to avoid creating a string instance.

hexEncode
public static String hexEncode(byte[] s)(Code)
	Converts a byte array into its hexadecimal notation.

hexEncode
public static String hexEncode(byte[] s, int offset, int length)(Code)
	Converts a part of a byte array into its hexadecimal notation.

hexEncode
public static String hexEncode(byte b)(Code)
	Converts a single byte into its hexadecimal notation.

hexEncode
public static String hexEncode(short s)(Code)
	Converts a short value (16-bit) into its hexadecimal notation.

hexEncode
public static String hexEncode(int i)(Code)
	Converts an int value (32-bit) into its hexadecimal notation.

hexEncode
public static String hexEncode(long l)(Code)
	Converts a long value (64-bit) into its hexadecimal notation.

hexEncodeObject
public static String hexEncodeObject(Object obj)(Code)

main
public static void main(String args) throws IOException(Code)
	For testing.
