=head1 NAME

SOAP::WSDL::Factory::Serializer - Factory for retrieving serializer objects

=head1 SYNOPSIS

 # from SOAP::WSDL::Client:
 $serializer = SOAP::WSDL::Factory::Serializer->get_serializer({
     soap_version => $soap_version,
 });

 # in serializer class:
 package MyWickedSerializer;
 use SOAP::WSDL::Factory::Serializer;

 # register as serializer for SOAP1.2 messages
 SOAP::WSDL::Factory::Serializer->register( '1.2' , __PACKAGE__ );

=head1 DESCRIPTION

SOAP::WSDL::Factory::Serializer serves as factory for retrieving
serializer objects for SOAP::WSDL.

The actual work is done by specific serializer classes.

SOAP::WSDL::Serializer tries to load one of the following classes:

=over

=item * the class registered for the scheme via register()

=back

=head1 METHODS

=head2 register

 SOAP::WSDL::Serializer->register('1.1', 'MyWickedSerializer');

Globally registers a class for use as serializer class.

=head2 get_serializer

Returns an object of the serializer class for this endpoint.

=head1 WRITING YOUR OWN SERIALIZER CLASS

=head2 Registering a deserializer

Serializer classes may register with SOAP::WSDL::Factory::Serializer.

Serializer objects may also be passed directly to SOAP::WSDL::Client by
using the set_serializer method. Note that serializers objects set via
SOAP::WSDL::Client's set_serializer method are discarded when the SOAP
version is changed via set_soap_version.

Registering a serializer class with SOAP::WSDL::Factory::Serializer is done
by executing the following code where $version is the SOAP version the
class should be used for, and $class is the class name.

 SOAP::WSDL::Factory::Serializer->register( $version, $class);

To auto-register your transport class on loading, execute register() in
your tranport class (see L</SYNOPSIS> above).

=head2 Serializer package layout

Serializer modules must be named equal to the serializer class they contain.
There can only be one serializer class per serializer module.

=head2 Methods to implement

Serializer classes must implement the following methods:

=over

=item * new

Constructor.

=item * serialize

Serializes data to XML. The following named parameters are passed to the
serialize method in a anonymous hash ref:

 {
   method => $operation_name,
   header => $header_data,
   body => $body_data,
 }

=back
