.\" way too many mistakes in technical documents.

.SH "NAME"
CGI::Session::Serialize::yaml \- serializer for CGI::Session
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This library can be used by CGI::Session to serialize session data. It uses
\&\f(CW\*(C`YAML\*(C'\fR, or the faster C implementation, \f(CW\*(C`YAML::Syck\*(C'\fR
if it is available. \s-1YAML\s0 serializers exist not just for Perl but also other
dynamic languages, such as \s-1PHP,\s0 Python, and Ruby, so storing session data
in this format makes it easy to share session data across different languages.
.PP
\&\s-1YAML\s0 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.
.SH "METHODS"
.IX Header "METHODS"
.IP "freeze($class, \e%hash)" 4
.IX Item "freeze($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 \f(CW\*(C`set_error()|CGI::Session::ErrorHandler/"set_error()"\*(C'\fR
.ie n .IP "thaw($class, $string)" 4
.el .IP "thaw($class, \f(CW$string\fR)" 4
.IX Item "thaw($class, $string)"
Received two arguments. First is the class name, second is the \f(CW\*(C`YAML\*(C'\fR data string. Should return thawed data structure on success, undef on failure. Error message should be set using \f(CW\*(C`set_error()|CGI::Session::ErrorHandler/"set_error()"\*(C'\fR
