Exception::Class 1.23

Exception::Class is a Perl module that allows you to declare real exception classes in Perl. SYNOPSIS use Exception::Class ( MyException, AnotherException => { isa => MyException }, YetAnotherException => { isa => AnotherException, description => These exceptions are related to IPC }, ExceptionWithFields => { isa => YetAnotherException, fields => [ grandiosity, quixotic ], alias => throw_fields, }, ); # try eval { MyException->throw( error => I feel funny. ) }; my $e; # catch if ( $e = Exception::Class->caught(MyException) ) { warn $e->error, "n", $e->trace->as_string, "n"; warn join , $e->euid, $e->egid, $e->uid, $e->gid, $e->pid, $e->time; exit; } elsif ( $e = Exception::Class->caught(ExceptionWithFields) ) { $e->quixotic ? do_something_wacky() : do_something_sane(); } else { $e = Exception::Class->caught(); ref $e ? $e->rethrow : die $e; } # use an alias - without parens subroutine name is checked at # compile time throw_fields error => "No strawberry", grandiosity => "quite a bit"; Exception::Class allows you to declare exception hierarchies in your modules in a "Java-esque" manner. It features a simple interface allowing programmers to declare exception classes at compile time. It also has a base exception class, Exception::Class::Base, that can be easily extended. It is designed to make structured exception handling simpler and better by encouraging people to use hierarchies of exceptions in their applications, as opposed to a single catch-all exception class. This module does not implement any try/catch syntax. Please see the "OTHER EXCEPTION MODULES (try/catch syntax)" section for more information on how to get this syntax..
