App::Exceptions - Creates all exception classes used in App.
use App::Exceptions;
Using this class creates all the exceptions classes used by App (via the Exception::Class class). Stacktrace generation is turned on for all the exception classes.
See Exception::Class on CPAN for more information on how this is done.
Note that there is really only one general exception class defined for each App-Context Service. Within each Service, there may be a separate exception hierarchy which is more fine-grained. However, each service is responsible to (1) handle these exceptions, (2) handle these exceptions and rethrow the general exception defined for the service, or (3) derive all of the exceptions from the general exception.
App::Exception
This is the base class for all exceptions generated within App (all exceptions should return true for $@->isa('App::Exception') except those that are generated via internal Perl errors).
$@->isa('App::Exception')
App::Exception::Context
Base class for all Context-related exceptions.
App::Exception::Conf
Base class for all Conf-related exceptions.
App::Exception::Serializer
Base class for all Serializer-related exceptions.
App::Exception::Security
Base class for all Security-related exceptions.
App::Exception::Session
Base class for all Session-related exceptions.
App::Exception::Procedure
