Class Parser

A data string parser.

Parsers are capable of parsing one particular data format, which is passed to them during construction.

The parser is created through BarcodePicker.createParserForFormat or Scanner.createParserForFormat. Note that you need to have a valid license with the parsing feature enabled to use the parser functionalities.

For documentation on the available formats, check the official parser library documentation here: https://docs.scandit.com/parser/formats.html.

Methods

parseRawData

  • Process the given raw data with the parser, retrieving the result as a ParserResult object.

    Multiple requests done without waiting for previous results will be queued and handled in order.

    If parsing of the data fails the returned promise is rejected with a ScanditEngineError error.

    Parameters

    • dataRaw: Uint8Array

      The raw data to be parsed.

    Returns Promise<ParserResult>

    A promise resolving to the ParserResult object.

parseString

  • Process the given string data with the parser, retrieving the result as a ParserResult object.

    Multiple requests done without waiting for previous results will be queued and handled in order.

    If parsing of the data fails the returned promise is rejected with a ScanditEngineError error.

    Parameters

    • dataString: string

      The string to be parsed.

    Returns Promise<ParserResult>

    A promise resolving to the ParserResult object.

setOptions

  • setOptions(options: object): void
  • Apply the option map to the parser, allowing the user to fine-tune the behaviour of the parser. Available options depend on the data format and are specified in the respective documentation.
