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.
