(** XmlRpc Light server. *)
(** Example: {[
let server = new XmlRpcServer.cgi () in
server#register "demo.sayHello"
(fun _ -> `String "Hello!");
server#run () ]}
By inheriting from {!XmlRpcServer.base}, all servers provide
the following introspection functions by default: [system.listMethods],
[system.getCapabilities]. To prevent their use, use [server#unregister].
Additionally, the methods [system.methodHelp] and [system.methodSignature]
will be made available if at least one method help or method signature is
provided.

(** Type of parameters used in method signatures. *)
type param_type =
[ `Array | `Binary | `Boolean | `DateTime | `Double
| `Int | `String | `Struct | `Undefined ]
(** {2 Base classes} *)
(** Abstract base class for XmlRpc servers. *)

(** ISO-8601 date/time encoding function. *)
val mutable datetime_encoder : XmlRpcDateTime.t -> string
(** ISO-8601 date/time decoding function. *)
val mutable datetime_decoder : string -> XmlRpcDateTime.t
(** Handler for unhandled exceptions. *)
val mutable error_handler : exn -> XmlRpc.message
(** Sets an alternate Base-64 binary encoding function. *)

(** Sets an alternate Base-64 binary decoding function. *)

(** Sets an alternate ISO-8601 date/time encoding function. *)

See {!XmlRpc.default_error_handler} and
{!XmlRpc.quiet_error_handler} for examples. *)
method set_error_handler : (exn -> XmlRpc.message) -> unit
(** For use in subclasses; calls {!XmlRpc.serve} with the current
encoders, decoders, and error handler. *)
method serve :
(string -> XmlRpc.value list -> XmlRpc.value) -> string -> string
(** Like [serve], but operates on messages instead of strings. *)
method serve_message :
(string -> XmlRpc.value list -> XmlRpc.value) ->
XmlRpc.message -> XmlRpc.message
(** Registers a method with the server.
If a [help] string is specified, its contents will be returned for
calls to [system.methodHelp] for this method.
If [signature] is specified, this method's signature will be published
by [system.methodSignature] and (shallow) type-checking will be enabled
for parameters passed into this method.
Multiple signatures can be supplied via [signatures] if desired to
provide for overloaded methods.
Signatures are of the form [return-type; param1-type; param2-type; ...]
where each type is an instance of the {!param_type} variant. *)
