Method Detail

printInHex

public static void printInHex(byte b)
print byte in Hex.
Takes a byte as an argument and prints its value in Hex. For example the number 255 will print FF with no new line.
Parameters:
b - byte to convert to hex

nibbleToHex

public static byte nibbleToHex(byte nibble)
nibble To hex.
This will take a nibble (4 low bits of the byte passed) and convert it into the Hex value. If the value of nibble is greater than 4 bits, the 4 high bits will be filtered.
Parameters:
nibble - Byte with a 4 bit value to convert to Hex.
Returns:
hex value

asciiHexToNibble

public static byte asciiHexToNibble(byte b)
Converting an ascii nibble in decimal ( [0-9a-f-A-F] should be in the hex range) to a 4 bit number which is the hex value (nibble).
The ascii value passed should be in the range of [a-fA-F0-9]. There is a catch for this function, if the value passed can not be converted to Hex, because it is not within this ascii range [a-fA-F0-9] the result will be the same value passed from the user. We may change later to raise an exception in this case.

nibble of the result

Parameters:
b - byte with a hex value to convert to decimal
Returns:
converted value of 4 bits (if not an error)

bArray2nibbles

public static void bArray2nibbles(byte[] array,
                                  byte[] nibbles)
Byte array to nibbles.
Takes an array of bytes and converts it into an array of nibbles. The nibbles array must be at least double the size of array.
Parameters:
array - array of bytes to convert
nibbles - array where the nibbles will be stored

bArray2String

public static java.lang.String bArray2String(byte[] array)
Byte array to String.
Takes an array of bytes and converts it into a String containing its hex reprenstation.
Parameters:
array - array of bytes to convert

nibbles2bArray

public static byte[] nibbles2bArray(byte[] nibbles)
Nibbles to byte array.
Puts an array of nibbles into an array of bytes (2 nibbles per byte)
Parameters:
nibbles - array of nibbles
Returns:
array array of bytes

printInHex

public static void printInHex(long value)

printInHex

public static void printInHex(int value)

printInHex

public static void printInHex(short value)

toHex
