=head1 NAME
CGI::Session::ErrorHandler - error handling routines for CGI::Session
=head1 SYNOPSIS
require CGI::Session::ErrorHandler;
@ISA = qw( CGI::Session::ErrorHandler );
sub some_method {
my $self = shift;
unless ( $some_condition ) {
return $self->set_error("some_method(): \$some_condition isn't met");
}
}
=head1 DESCRIPTION
CGI::Session::ErrorHandler provides set_error() and errstr() methods for setting and accessing error messages from within CGI::Session's components. This method should be used by driver developers for providing CGI::Session-standard error handling routines for their code
=head2 METHODS
=over 4
=item set_error($message)
Implicitly defines $pkg_name::errstr and sets its value to $message. Return value is B<always> undef.
=cut
sub set_error {
my $class = shift;
my $message = shift;
$class = ref($class) || $class;
no strict 'refs';
${ "$class\::errstr" } = $message || "";
return;
}
=item errstr()
Returns whatever value was set by the most recent call to set_error(). If no message as has been set yet, the empty string is returned so the message can still concatenate without a warning.
=back
=cut
*error = \&errstr;
sub errstr {
my $class = shift;
$class = ref( $class ) || $class;
no strict 'refs';
return ${ "$class\::errstr" } || '';
}
