📖 NAME

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

🚀 Quick Reference

📜 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 has been set yet, the empty string is returned so the message can still concatenate without a warning.
