Detailed Description

Make it easy to implement a network service.

See also:

ThreadedSocketService, SocketListener.

A SocketService is an object that represents a service that is provided to the network or over local sockets. When a new connection is made to the service the SocketService:incoming signal is emitted.

A SocketService is a subclass of SocketListener and you need to add the addresses you want to accept connections on to the with the SocketListener APIs.

There are two options for implementing a network service based on SocketService. The first is to create the service using g_socket_service_new() and to connect to the SocketService:incoming signal. The second is to subclass SocketService and override the default signal handler implementation.

In either case, the handler must immediately return, or else it will block additional incoming connections from being serviced. If you are interested in writing connection handlers that contain blocking code then see ThreadedSocketService.

The socket service runs on the main loop in the main thread, and is not threadsafe in general. However, the calls to start and stop the service are threadsafe so these can be used from threads that handle incoming clients.

[static]

Reimplemented from Gio::SocketListener.

GSocketService* Gio::SocketService::gobj

[inline]

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketListener.

Reimplemented in Gio::ThreadedSocketService.

const GSocketService* Gio::SocketService::gobj

const [inline]

Provides access to the underlying C GObject.

Reimplemented from Gio::SocketListener.

GSocketService* Gio::SocketService::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

Reimplemented from Gio::SocketListener.

Reimplemented in Gio::ThreadedSocketService.

bool Gio::SocketService::is_active

(

)

Check whether the service is active or not.

An active service will accept new clients that connect, while a non-active service will let connecting clients queue up until the service is started.

Since glibmm 2.22:

Returns:

true if the service is active, false otherwise.

Prototype:

bool on_my_incoming(const Glib::RefPtr<SocketConnection>& connection, const Glib::RefPtr<Glib::Object>& source_object)

void Gio::SocketService::start

(

)

Starts the service, i.e. start accepting connections from the added sockets when the mainloop runs.

This call is threadsafe, so it may be called from a thread handling an incomming client request.

Since glibmm 2.22:

void Gio::SocketService::stop

(

)

Stops the service, i.e. stops accepting connections from the added sockets when the mainloop runs.

This call is threadsafe, so it may be called from a thread handling an incomming client request.

Glib::RefPtr< Gio::SocketService > wrap	(	GSocketService *	object,
		bool	take_copy = false
	)		[related]

A Glib::wrap() method for this object.

Parameters:

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:

A C++ instance that wraps this C instance.
