instance method XMLRPC::BasicServer#set_service_hook

set_service_hook(&handler)[permalink][rdoc]

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
}
