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.
