NAME

CGI::Session::ErrorHandler - error handling routines for CGI::Session

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");
        }
    }

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

METHODS

Implicitly defines $pkg_name::errstr and sets its value to $message. Return value is always undef.
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.
