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.

NAME

       CGI::Session::Serialize::yaml - serializer for CGI::Session

DESCRIPTION

       This library can be used by CGI::Session to serialize session data. It uses "YAML", or the faster C implementation, "YAML::Syck" if it is
       available. YAML serializers exist not just for Perl but also other dynamic languages, such as PHP, Python, and Ruby, so storing session
       data in this format makes it easy to share session data across different languages.

       YAML is made to be friendly for humans to parse as well as other computer languages. It creates a format that is easier to read than the
       default serializer.

METHODS

       freeze($class, \%hash)
	   Receives two arguments. First is the class name, the second is the data to be serialized. Should return serialized string on success,
	   undef on failure. Error message should be set using "set_error()|CGI::Session::ErrorHandler/"set_error()""

       thaw($class, $string)
	   Received two arguments. First is the class name, second is the "YAML" data string. Should return thawed data structure on success,
	   undef on failure. Error message should be set using "set_error()|CGI::Session::ErrorHandler/"set_error()""
