CGI::Session::ErrorHanUser(Contributed Perl DocumCGI::Session::ErrorHandler(3)

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.
