NAME

       XML::Compile::SOAP::Server - server-side SOAP message processing

INHERITANCE

        XML::Compile::SOAP::Server is extended by
          XML::Compile::SOAP11::Server
          XML::Compile::SOAP12::Server

SYNOPSIS

         # used by distribution XML::Compile::SOAP::Daemon

         my $soap   = XML::Compile::SOAP11::Server->new;
         my $input  = $soap->compileMessage('RECEIVER', ...);
         my $output = $soap->compileMessage('SENDER', ...);

         $soap->compileHandler
           ( name => $name, input => $input, output => $output
           , callback => \$my_handler
           );

         my $daemon = XML::Compile::SOAP::HTTPDaemon->new(...);
         $daemon->addHandler($type => $daemon);

DESCRIPTION

       This class defines methods that each server for the SOAP message exchange protocols must
       implement.

METHODS

   Instantiation
       This object can not be instantiated, but is only used as secundary base class.  The
       primary must contain the "new".

       XML::Compile::SOAP::Server->new(%options)
            -Option--Default
             role    'NEXT'

           role => URI
             In SOAP1.1, the term is 'actor', but SOAP1.2 has renamed this into 'role': the role
             [this daemon] plays in the transport protocol.

             Please use the role abbreviations as provided by the protocol implementations when
             possible: they will be translated into the right URI on time.  See
             XML::Compile::SOAP::roleAbbreviation() and the constants defined in
             XML::Compile::SOAP::Util

   Accessors
       $obj->role()
           Returns the URI of the role (actor) of this server.

   Actions
       $obj->compileFilter(%options)
           This routine returns a CODE reference which can be used for compileHandler(selector);
           so see whether a certain message has arrived.  On the moment, only the first "body"
           element is used to determine that.

            -Option--Default
             body    []
             fault   <undef>
             header  <undef>
             style   'document'

           body => ARRAY-of-TYPES
           fault => ARRAY-of-TYPES
           header => ARRAY-of-TYPES
           style => 'rpc'|'document'
       $obj->compileHandler(%options)
           Returns an HTTP status code and an XML::LibXML::Document pair.

            -Option  --Default
             callback  <fault: not implemented>
             decode    <undef>
             encode    <undef>
             name      <required>
             selector  sub {0}

           callback => CODE
             As input, the SERVER object and the translated input message (Perl version) are
             passed in.  As output, a suitable output structure must be produced.  If the
             callback is not set, then a fault message will be returned to the user.

           decode => CODE
             The CODE reference is used to decode the (parsed) XML input message into the pure
             Perl request.  The reference is a READER, created with
             XML::Compile::Schema::compile().  If no input decoder is specified, then the
             callback handler will be called with the un-decoded XML::LibXML::Document node.

           encode => CODE
             The CODE reference is used to encode the Perl answer structure into the output
             message.  The reference is a WRITER.  created with XML::Compile::Schema::compile().
             If no output encoder is specified, then the callback must return an
             XML::LibXML::Document, or only produce error messages.

           name => STRING
             The identification for this action, for instance used for logging.  When the action
             is created via a WSDL, the portname will be used here.

             It is a pity that the portname is not passed in the SOAP message, because it is not
             so easy to detect which handler must be called.

           selector => CODE
             One way or the other, you have to figure-out whether a message addresses a certain
             process. The callback will only be used if the CODE reference specified here returns
             a true value.

             The CODE reference will be called with the XML version of the message, and a HASH
             which contains the information about the XML collected with
             XML::Compile::SOAP::messageStructure() plus the "soap_version" entry.

       XML::Compile::SOAP::Server->faultWriter()
           Returns a CODE reference which can be used to produce faults.
