NAME
POE::Exceptions - 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 "die"'ing.) 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.
