Class Method Details

.verify(line) ⇒ Object

Computes the CRC checksum of the given line and verifies that this value corresponds with the checksum given at the end of the line. Raises an error if the two values does not match.

Parameters

• line – An single line string from an RTPConnect ascii file.

Raises:

• (ArgumentError)

# File 'lib/rtp-connect/methods.rb', line 17

def verify(line)
  last_comma_pos = line.rindex(',')
  raise ArgumentError, "Invalid line encountered; No comma present in the string: #{line}" unless last_comma_pos
  string_to_check = line[0..last_comma_pos]
  string_remaining = line[(last_comma_pos+1)..-1]
  raise ArgumentError, "Invalid line encountered; Valid checksum missing at end of string: #{string_remaining}" unless string_remaining.length >= 3
  checksum_extracted = string_remaining.value.to_i
  checksum_computed = string_to_check.checksum
  raise ArgumentError, "Invalid line encountered: Specified checskum #{checksum_extracted} deviates from the computed checksum #{checksum_computed}." if checksum_extracted != checksum_computed
  return true
