+= XMLRPC::BasicServer
+== Description
+Is the base class for all XML-RPC server-types (CGI, standalone).
+You can add handler and set a default handler. 
+Do not use this server, as this is/should be an abstract class.
+
+=== How the method to call is found
+The arity (number of accepted arguments) of a handler (method or (({Proc})) object) is 
+compared to the given arguments submitted by the client for a RPC ((-Remote Procedure Call-)). 
+A handler is only called if it accepts the number of arguments, otherwise the search 
+for another handler will go on. When at the end no handler was found, 
+the ((<default_handler|XMLRPC::BasicServer#set_default_handler>)) will be called.
+With this technique it is possible to do overloading by number of parameters, but
+only for (({Proc})) handler, because you cannot define two methods of the same name in
+the same class. 
+
+
+== Class Methods
+--- XMLRPC::BasicServer.new( class_delim="." )
+    Creates a new (({XMLRPC::BasicServer})) instance, which should not be 
+    done, because (({XMLRPC::BasicServer})) is an abstract class. This
+    method should be called from a subclass indirectly by a (({super})) call
+    in the method (({initialize})). The paramter ((|class_delim|)) is used
+    in ((<add_handler|XMLRPC::BasicServer#add_handler>)) when an object is
+    added as handler, to delimit the object-prefix and the method-name.
+
+== Instance Methods
+--- XMLRPC::BasicServer#add_handler( name, signature=nil, help=nil ) { aBlock }
+    Adds ((|aBlock|)) to the list of handlers, with ((|name|)) as the name of the method.
+    Parameters ((|signature|)) and ((|help|)) are used by the Introspection method if specified, 
+    where ((|signature|)) is either an Array containing strings each representing a type of it's 
+    signature (the first is the return value) or an Array of Arrays if the method has multiple 
+    signatures. Value type-names are "int, boolean, double, string, dateTime.iso8601, base64, array, struct".
+
+    Parameter ((|help|)) is a String with informations about how to call this method etc.
+
+    A handler method or code-block can return the types listed at
+    ((<XMLRPC::Client#call|URL:client.html#index:0>)). 
+    When a method fails, it can tell it the client by throwing an 
+    (({XMLRPC::FaultException})) like in this example:
+        s.add_handler("michael.div") do |a,b|
+          if b == 0
+            raise XMLRPC::FaultException.new(1, "division by zero")
+          else
+            a / b 
+          end
+        end 
+    The client gets in the case of (({b==0})) an object back of type
+    (({XMLRPC::FaultException})) that has a ((|faultCode|)) and ((|faultString|))
+    field.
+
+--- XMLRPC::BasicServer#add_handler( prefix, obj )
+    This is the second form of ((<add_handler|XMLRPC::BasicServer#add_handler>)).
+    To add an object write:
+        server.add_handler("michael", MyHandlerClass.new)
+    All public methods of (({MyHandlerClass})) are accessible to
+    the XML-RPC clients by (('michael."name of method"')). This is 
+    where the ((|class_delim|)) in ((<new|XMLRPC::BasicServer.new>)) 
+    has it's role, a XML-RPC method-name is defined by 
+    ((|prefix|)) + ((|class_delim|)) + (('"name of method"')). 
+
+--- XMLRPC::BasicServer#add_handler( interface, obj )
+    This is the third form of ((<add_handler|XMLRPC::BasicServer#add_handler>)).
+
+    Use (({XMLRPC::interface})) to generate an ServiceInterface object, which
+    represents an interface (with signature and help text) for a handler class.
+
+    Parameter ((|interface|)) must be of type (({XMLRPC::ServiceInterface})).
+    Adds all methods of ((|obj|)) which are defined in ((|interface|)) to the
+    server.
+
+    This is the recommended way of adding services to a server!
+
+
+--- XMLRPC::BasicServer#get_default_handler
+    Returns the default-handler, which is called when no handler for
+    a method-name is found.
+    It is a (({Proc})) object or (({nil})).
+
+--- XMLRPC::BasicServer#set_default_handler ( &handler )
+    Sets ((|handler|)) as the default-handler, which is called when 
+    no handler for a method-name is found. ((|handler|)) is a code-block.
+    The default-handler is called with the (XML-RPC) method-name as first argument, and
+    the other arguments are the parameters given by the client-call.
+  
+    If no block is specified the default of (({XMLRPC::BasicServer})) is used, which raises a
+    XMLRPC::FaultException saying "method missing".
+
+
+--- XMLRPC::BasicServer#set_writer( writer )
+    Sets the XML writer to use for generating XML output.
+    Should be an instance of a class from module (({XMLRPC::XMLWriter})).
+    If this method is not called, then (({XMLRPC::Config::DEFAULT_WRITER})) is used. 
+
+--- XMLRPC::BasicServer#set_parser( parser )
+    Sets the XML parser to use for parsing XML documents.
+    Should be an instance of a class from module (({XMLRPC::XMLParser})).
+    If this method is not called, then (({XMLRPC::Config::DEFAULT_PARSER})) is used.
+
+--- XMLRPC::BasicServer#add_introspection
+    Adds the introspection handlers "system.listMethods", "system.methodSignature" and "system.methodHelp", 
+    where only the first one works.
+
+--- XMLRPC::BasicServer#add_multicall
+    Adds the multi-call handler "system.multicall".
+
+--- XMLRPC::BasicServer#get_service_hook
+    Returns the service-hook, which is called on each service request (RPC) unless it's (({nil})).
+
+--- XMLRPC::BasicServer#set_service_hook ( &handler )
+    A service-hook is called for each service request (RPC).
+    You can use a service-hook for example to wrap existing methods and catch exceptions of them or
+    convert values to values recognized by XMLRPC. You can disable it by passing (({nil})) as parameter  
+    ((|handler|)) .
+
+    The service-hook is called with a (({Proc})) object and with the parameters for this (({Proc})).
+    An example:
+
+       server.set_service_hook {|obj, *args|
+         begin
+           ret = obj.call(*args)  # call the original service-method
+           # could convert the return value 
+         resuce
+           # rescue exceptions
+         end
+       }

+
+== Description
+Implements a standalone XML-RPC server. The method (({serve}))) is left if a SIGHUP is sent to the
+program.
+
+== Superclass
+((<XMLRPC::WEBrickServlet>))
+
+== Class Methods
+--- XMLRPC::Server.new( port=8080, host="127.0.0.1", maxConnections=4, stdlog=$stdout, audit=true, debug=true, *a )
+    Creates a new (({XMLRPC::Server})) instance, which is a XML-RPC server listening on
+    port ((|port|)) and accepts requests for the host ((|host|)), which is by default only the localhost. 
+    The server is not started, to start it you have to call ((<serve|XMLRPC::Server#serve>)).
+
+    Parameters ((|audit|)) and ((|debug|)) are obsolete!
+
+    All additionally given parameters in ((|*a|)) are by-passed to ((<XMLRPC::BasicServer.new>)). 
+    
+== Instance Methods
+--- XMLRPC::Server#serve
+    Call this after you have added all you handlers to the server.
+    This method starts the server to listen for XML-RPC requests and answer them.
+
+--- XMLRPC::Server#shutdown
+    Stops and shuts the server down.
