NAME
CGI::Session::ErrorHandler - error handling routines for CGI::SessionSYNOPSIS
require CGI::Session::ErrorHandler @ISA = qw( CGI::Session::ErrorHandler ); sub some_method { my $self = shift; unless ( $some_condition ) { return $self->set_error("some_method(): \$some_condition isn't met"); } }
DESCRIPTION
CGI::Session::ErrorHandler provides set_error() and errstr() methods for setting and accessing error messages from within CGI::Session's components. This method should be used by driver developers for providing CGI::Session-standard error handling routines for their codeMETHODS
- set_error($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.
