CGI::Session::ErrorHanUser(Contributed Perl DocumCGI::Session::ErrorHandler(3)NAMECGI::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 $self->set_error("some_method(): \$some_condition isn't met");
}
}
DESCRIPTIONCGI::Session::ErrorHandler provides set_error() and errstr() methods
for setting and accessing error messages from within CGI::Session's
components. This method should be used by driver developers for
providing CGI::Session-standard error handling routines for their code
METHODS
set_error($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.
