/**
* <p>
* 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.
* {@link ResultParser#parseResult(com.google.zxing.Result)} will turn a raw
* decoded string into the most appropriate type of structured representation.

* less on exception-based mechanisms during parsing.
