Instance Method Details

#=~(other) ⇒ Bool

Match operator. Checks to see if the other barcode, is a match for this one.

  • In the case of foreign barcodes we match only when the other barcode is equal to the machine_barcode

rubocop:todo Layout/LineLength

  • In the case of SBCF formatted barcodes (eg DN1234K/1220001234757) we delegate to the matcher in SBCF::SangerBarcode

rubocop:enable Layout/LineLength

This allows us to match either ean13 or code39 formatted barcodes (or the machine barcode to human readable
version in the case of older plates).

Parameters:

  • other (String) —

    The barcode to check

Returns:

  • (Bool) —

    True is the barcodes match, false otherwise.
