Method Detail

bytesToHex

public static String bytesToHex(byte[] bytes)

Parameters:

bytes - byte array that will be converted to hex

Returns:

the String containing converted hex values or null if byte array is null

bytesToHex

public static String bytesToHex(byte[] bytes,
                                int offset,
                                int length)

Parameters:

bytes - byte array that will be converted to hex

offset - int representing the offset to begin conversion at

length - int representing number of bytes in array to convert

Returns:

the String containing converted hex values or null if byte array is null, a null value if byte array is null, and an empty string if the offset is greater than the length

hexToBytes

public static byte[] hexToBytes(String hexString)

Parameters:

hexString - the String containing converted hex values

Returns:

byte array converted from input String or null if String is null

intToByteArray

public static final byte[] intToByteArray(int value)

intFromByteArray

public static int intFromByteArray(byte[] sizeBuf,
                                   int offset)

Parameters:

sizeBuf - byte array that will be converted to int

offset - The position indicating where to begin converting.

Returns:

int converted from byte array, -1 if byte array is null, and 0 if the offset is greater than the length of the byte array

shortToByteArray

public static final byte[] shortToByteArray(short value)

shortFromByteArray

public static short shortFromByteArray(byte[] sizeBuf,
                                       int offset)

Parameters:

sizeBuf - byte array that will be converted to short

offset - The position indicating where to begin converting.

Returns:

short converted from byte array, -1 if byte array is null, and 0 if the offset is greater than the length of the byte array

bytesToHex

public static String bytesToHex(byte[] bytes,
                                int end)

Converts the byte array into a string of hex values.

Parameters:

bytes - byte array that will be converted to hex

end - EXCLUSIVE so if it receives 10 it will print 0-9

Returns:

the String containing converted hex values or null if byte array is null
