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.

LICENSING
