def data_to_escaped_hex
  # First we convert the string into a packed hex string.
  hex_string = self.unpack('H*')[0]
  
  # Now we grab two elements at a time, prefix it, and add it to the buffer.
  ptr = 0
  len = self.bytesize
  outbuf = ""
  while(ptr<(len*2))
    outbuf << '\x' + hex_string[ptr,2]
    ptr+=2
  end
  
  # Now we return the buffer
  return outbuf
end

#data_to_hex ⇒ Object

Returns the hexidecimal string representation of the data.
