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.
