CGI::Session::ErrorHandler(3)              User Contributed Perl Documentation


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

       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.
