Class ResultParser

java.lang.Object

Direct Known Subclasses:

public abstract class ResultParser extends Object

Abstract class representing the result of decoding a barcode, as more than a String -- as some type of structured data. This might be a subclass which represents a URL, or an e-mail address. parseResult(Result) will turn a raw decoded string into the most appropriate type of structured representation.

Thanks to Jeff Griffin for proposing rewrite of these classes that relies less on exception-based mechanisms during parsing.

    • parse

      public abstract ParsedResult parse(Result theResult)
      Attempts to parse the raw Result's contents as a particular type of information (email, URL, etc.) and return a ParsedResult encapsulating the result of parsing.
      Parameters:
      theResult - the raw Result to parse
      Returns:
      ParsedResult encapsulating the parsing result
