=head1 NAME
DBIx::Class::Exception - Exception objects for DBIx::Class
=head1 DESCRIPTION
Exception objects of this class are used internally by
the default error handling of L<DBIx::Class::Schema/throw_exception>
and derivatives.
These objects stringify to the contained error message, and use
overload fallback to give natural boolean/numeric values.
=head1 METHODS
=head2 throw
=over 4
=item Arguments: $exception_scalar, $stacktrace
=back
This is meant for internal use by L<DBIx::Class>'s C<throw_exception>
code, and shouldn't be used directly elsewhere.
Expects a scalar exception message. The optional boolean C<$stacktrace>
causes it to output a full trace similar to L<confess|Carp/DESCRIPTION>.
DBIx::Class::Exception->throw('Foo');
try { ... } catch { DBIx::Class::Exception->throw(shift) }
=cut
sub throw {
my ($class, $msg, $stacktrace) = @_;
# Don't re-encapsulate exception objects of any kind
die $msg if ref($msg);
# all exceptions include a caller
$msg =~ s/\n$//;
if(!$stacktrace) {
# skip all frames that match the original caller, or any of
# the dbic-wide classdata patterns
my ($ln, $calling) = DBIx::Class::Carp::__find_caller(
'^' . caller() . '$',
'DBIx::Class',
);
$msg = "${calling}${msg} ${ln}\n";
}
else {
$msg = Carp::longmess($msg);
}
my $self = { msg => $msg };
bless $self => $class;
die $self;
}
=head2 rethrow
This method provides some syntactic sugar in order to
re-throw exceptions.
