NAME

       SOAP::WSDL::Factory::Transport - Factory for retrieving transport objects

SYNOPSIS

        # from SOAP::WSDL::Client:
        $transport = SOAP::WSDL::Factory::Transport->get_transport( $url, @opt );

        # in transport class:
        package MyWickedTransport;
        use SOAP::WSDL::Factory::Transport;

        # register class as transport module for httpr and https
        # (httpr is "reliable http", a protocol developed by IBM).
        SOAP::WSDL::Factory::Transport->register( 'httpr' , __PACKAGE__ );
        SOAP::WSDL::Factory::Transport->register( 'https' , __PACKAGE__ );

DESCRIPTION

       SOAP::WSDL::Transport serves as factory for retrieving transport objects for SOAP::WSDL.

       The actual work is done by specific transport classes.

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

       •   the class registered for the scheme via register()

       •   the SOAP::Lite class matching the scheme

       •   the SOAP::WSDL class matching the scheme

METHODS

   register
        SOAP::WSDL::Transport->register('https', 'MyWickedTransport');

       Globally registers a class for use as transport class.

   proxy
        $trans->proxy('http://soap-wsdl.sourceforge.net');

       Sets the proxy (endpoint).

       Returns the transport for this protocol.

   set_transport
       Sets the current transport object.

   get_transport
       Gets the current transport object.

WRITING YOUR OWN TRANSPORT CLASS

   Registering a transport class
       Transport classes must be registered with SOAP::WSDL::Factory::Transport.

       This is done by executing the following code where $scheme is the URL scheme the class
       should be used for, and $module is the class' module name.

        SOAP::WSDL::Factory::Transport->register( $scheme, $module);

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

       Multiple protocols or multiple classes are registered by multiple calls to register().

   Transport plugin package layout
       You may only use transport classes whose name is either the module name or the module name
       with '::Client' appended.

   Methods to implement
       Transport classes must implement the interface required for SOAP::Lite transport classes
       (see SOAP::Lite::Transport for details, SOAP::WSDL::Transport::HTTP for an example).

       To provide this interface, transport modules must implement the following methods:

       •   new

       •   send_receive

           Dispatches a request and returns the content of the response.

       •   code

           Returns the status code of the last send_receive call (if any).

       •   message

           Returns the status message of the last send_receive call (if any).

       •   status

           Returns the status of the last send_receive call (if any).

       •   is_success

           Returns true after a send_receive was successful, false if it was not.

       SOAP::Lite requires transport modules to pack client and server classes in one file, and
       to follow this naming scheme:

        Module name:
          "SOAP::Transport::" . uc($scheme)

        Client class (additional package in module):
          "SOAP::Transport::" . uc($scheme) . "::Client"

        Server class (additional package in module):
          "SOAP::Transport::" . uc($scheme) . "::Client"

       SOAP::WSDL does not require you to follow these restrictions.

       There is only one restriction in SOAP::WSDL:

       You may only use transport classes whose name is either the module name or the module name
       with '::Client' appended.

       SOAP::WSDL will try to instantiate an object of your transport class with '::Client'
       appended to allow using transport classes written for SOAP::Lite.

       This may lead to errors when a different module with the name of your transport module
       suffixed with ::Client is also loaded.
