• decode(self, barcode_string)
  @api.model
  Decode a GS1-128/GS1-Datamatrix string to dictionary of values with Application Identifiers as keys. Please note that the string MUST contain a <GS> character (group separator) after each variable-length value. <GS> is usually expected to be sent as ASCII character 29 but that may be configured per user. If the same Application Identifier is present several times in the string, only the its last value is returned. @type barcode_string: string @param barcode_string: GS1-128/GS1-Datamatrix string to decode @return: A dictionary of values with Application Identifiers as keys
