http://issues.apache.org/bugzilla/show_bug.cgi?id=34103 ------- Additional Comments From [EMAIL PROTECTED] 2005-03-22 08:08 ------- ok, here's my suggestion of how Configuration should be modeled. The basic methods will be: Object getProperty(String key) throws PropertyDoesNotExistException; Object getProperty(String key, Object default) throws ConversionException; Object getProperty(String key, Class cls) throws PropertyDoesNotExistException, ConversionException; Object getProperty(String key, Converter conv) throws PropertyDoesNotExistException, ConversionException; Object getProperty(String key, Object default, Converter conv) throws ConversionException; (the exceptions can/should be RuntimeExceptions, or other exceptions, like NoSuchElementException) all the rest of the getXXX() methods are syntactic sugar, one-liners that call one of the getProperty() methods (second and third forms). Converter has the API: convert(Objec o, Class cls) to convert o to an instance of cls. converters can be registered as converting to some class (which is what getProperty(key,cls) uses. that's it, simple (the client needs to know only of the first 2 forms if he is not interested in sophisticated conversions, and the return values are very consistent, no need to read the documentation for each getXXX() method), yet powerful (allowing me, for example, to convert a property to Map, Date etc. very easily) note that most of the implementation will be in getProperty(key, default, converter) while the rest just call it (sometimes checking containsKey() before) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
