                          long offset,
                          int index)

dump an array of bytes to a String

Parameters:

data - the byte array to be dumped

offset - its offset, whatever that might mean

index - initial index into the byte array

Returns:

output string

Throws:

ArrayIndexOutOfBoundsException - if the index is outside the data array's bounds

toHex

public static String toHex(byte[] value)

Dumps the byte array in hexadecimal format.

Parameters:

value - The value to convert

Returns:

A String representing the array of bytes

toHex

public static String toHex(byte[] value,
                           int offset,
                           int length)

dump a part of the array of bytes to a String

Parameters:

value - the byte array to be dumped

offset - starting index into the byte array

length - length of the byte array to dump.

Returns:

output string

toHex
