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.
