perlquestion je44ery I'm using Exception::Class to define my exceptions classes, but I just stumbled into a design question. Should create lots of exception subclasses like this? <code> MyExceptions::SomeThingy MyExceptions::SomeThingy::SomeSpecificError MyExceptions::SomeThingy::AnotherProblem MyExceptions::SomeThingy::DontDoThat </code> But if the subclasses SomeSpecificError, AnotherProblem, DontDoThat aren't different, then why have them? I was thinking of replacing those subclasses with fields under SomeThingy. Like this: <code> MyException::SomeThingy' => { isa => 'MyException', description => 'Bad things happen here.', fields => [ 'descriptor', 'value' ], }; </code> And then I throw them: <code> MyException::SomeThingy->throw( 'error' => 'You did something I didnt like.', 'descriptor' => 'DontDoThat', 'value' => $bad_variable, ); </code> Hmmm. So I guess my question is, if all those subclasses do the same thing, am I getting anything out of creating them all? Other than the name of the exception itself tells me something about the error? If that is all I am gaining, then doesn't using fields make more sense? I'm new to OO, and new to using Perl as anything other than a glorified awk. Thanks. <p> <b>UPDATE:</b> [href://http://java.sun.com/developer/technicalArticles/Programming/exceptions/|This page] covers what I was asking, too, in the paragraph titled "Write Sensible Throws Clauses".
