POE::Exceptions 0.0502

POE::Exceptions is a POE class for handling exceptions. SYNOPSIS use POE::Exceptions; POE::Session::Exception->create( inline_states => { _start => sub { print START; $_[KERNEL]->sig(DIE,death_handled); }, death_handled => sub { print EXCEPTION CAUGHT $_[KERNEL]->sig_handled(); }, _stop => { print END } } ); $poe_kernel->run(); DEPRECATION This module is deprecated as its functionality has been rolled into the POE core, as of POE 0.33. This module will receive no updates and will be removed from CPAN at some point in the near future. DISCUSSION POE::Exceptions extends POE to catch exceptions neatly. A new signal, DIE, is introduced. This signal will be fired every time an exception occurs. (For those of you new to the term exception, an exception is whenever the code decides to bail out by dieing.) If the signal handler returns 1 (as in the example above), POE will assume that the handler dealt with the signal appropriately. If the signal handler returns 0, POE will assume that the handler does not want to deal with the signal and POE will propgate the exception as if the handler never existed. Caveat: POE::Exceptions will die on its own in the case of a double exception fault. If the DIE signal handler itself throws an exception, POE::Exceptions will shut the program down and bail out..
