NAME

       SOAP::Schema - provides an umbrella for the way in which SOAP::Lite manages service
       description schemas

DESCRIPTION

       This class provides an umbrella for the way in which SOAP::Lite manages service
       description schemas. Currently, the only support present is for the Web Services
       Description Language (WSDL). This is another of the classes not generally designed to be
       directly instantiated by an application, though it can be if so desired.

METHODS

       new(optional key/value pairs)
               $schema = SOAP::Schema->new(parse => $schema_uri);

           This is the class constructor. With no arguments, it creates a blank object of the
           class. Any arguments that are passed are treated as key/value pairs in which the key
           represents one of the methods described here, and the value is what gets passed when
           the method itself gets invoked.

       parse(service description URI)
               $schema->parse('http://schemas.w3.org/soap.wsdl');

           Parses the internal representation of the service description prior to the generation
           of stub routines to provide method-like access to the remote services.

       access(service description URI)
               $schema->access('http://soap.org/service.wsdl');

           Loads the specified service description from the given URL, using the current value of
           the schema accessor if none is provided. The full content of the URL is returned on
           success, or an exception is thrown (via "die") on error.

       load
               $schema->load;

           Takes the internal representation of the service and generates code stubs for the
           remote methods, allowing them to be called as local object methods. Stubs are
           generated for all the functions declared in the WSDL description with this call
           because it's enough of a class framework to allow for basic object creation for use as
           handles.

       schema
               $current_schema = $schema->schema;

           Gets (or sets) the current schema representation to be used by this object. The value
           to be passed when setting this is just the URI of the schema. This gets passed to
           other methods such as access for loading the actual content.

       services
               $hashref = $schema->services;

           Gets or sets the services currently stored on the object. The services are kept as a
           hash reference, whose keys and values are the list of returned values from the WSDL
           parser. Keys represent the names of the services themselves (names have been
           normalized into Perl-compatible identifiers), with values that are also hash
           references to the internal representation of the service itself.

       stub
           Returns the autogenerated Perl code as a string. This code is generated from the WSDL
           provided by the "service" method call. The code contains a package definition for the
           service being called.

               my $client = SOAP::Lite->new;
               my $code = $client->service($WSDL_URL)->stub;
               open FILE,">ServicePackage.pm";
               print FILE $code;
               close FILE;

       cache_dir
           Sets/retrieves the value of the directory where generated stubs will be cached. If
           "cache_dir" is null, then no caching will be performed.

               my $client = SOAP::Lite->new;
               my $code = $client->cache_dir("/tmp")->service($WSDL_URL)->stub;

           If "cache_dir" is undefined, no caching will take place.

       cache_ttl
           Sets/retrieves the value of the time to live (in seconds) for cached files. This is
           only relevant when used in conjunction with "cache_dir".

           If "cache_ttl" is set to 0, the cache will never expire. Files will have to be removed
           manually in order for the cache to be refreshed.

               my $client = SOAP::Lite->new;
               my $code = $client->cache_ttl(3600)->cache_dir("/tmp")->service($WSDL_URL)->stub;

           The default time to live is 0.

       useragent(LWP::UserAgent)
               my $client = SOAP::Lite->new;
               $ua = $client->schema->useragent;
               $ua->agent("Fubar! 0.1");
               my $response = $client->service("http://localhost/some.wsdl")
                                     ->someMethod("Foo");

           Gets or sets the classes UserAgent used for retrieving schemas over the web.  This
           allows users to have direct access to the UserAgent so that they may control the
           credentials passed to a remote server, or the specific configuration of their HTTP
           agent.

SOAP::Schema::WSDL

       At present, the SOAP::Lite toolkit supports only loading of service descriptions in the
       WSDL syntax. This class manages the parsing and storing of these service specifications.
       As a general rule, this class should be even less likely to be used directly by an
       application because its presence should be completely abstracted by the previous class
       (SOAP::Schema). None of the methods are defined here; the class is only mentioned for sake
       of reference.
