GI.Gio.Objects.DBusServer

Contents

Description

DBusServer is a helper for listening to and accepting D-Bus connections. This can be used to create a new D-Bus server, allowing two peers to use the D-Bus protocol for their own specialized communication. A server instance provided in this way will not perform message routing or implement the org.freedesktop.DBus interface.

To just export an object on a well-known name on a message bus, such as the session or system bus, you should instead use g_bus_own_name().

An example of peer-to-peer communication with G-DBus can be found in gdbus-example-peer.c.

class GObject o => IsDBusServer o Source #

Type class for types which can be safely cast to DBusServer, for instance with toDBusServer.

toDBusServer :: (MonadIO m, IsDBusServer o) => o -> m DBusServer Source #

Cast to DBusServer, for types for which this is known to be safe. For general casts, use castTo.

Methods

getClientAddress

dBusServerGetClientAddress Source #

Arguments

:: (HasCallStack, MonadIO m, IsDBusServer a) 
=> a

server: A DBusServer.

-> m Text

Returns: A D-Bus address string. Do not free, the string is owned by server.

Gets a D-Bus address string that can be used by clients to connect to server.

Since: 2.26

getFlags

dBusServerGetFlags Source #

Arguments

:: (HasCallStack, MonadIO m, IsDBusServer a) 
=> a

server: A DBusServer.

-> m [DBusServerFlags]

Returns: A set of flags from the DBusServerFlags enumeration.

Gets the flags for server.

Since: 2.26

getGuid

dBusServerGetGuid Source #

Arguments

:: (HasCallStack, MonadIO m, IsDBusServer a) 
=> a

server: A DBusServer.

-> m Text

Returns: A D-Bus GUID. Do not free this string, it is owned by server.

Gets the GUID for server.

Since: 2.26

isActive

dBusServerIsActive Source #

Arguments

:: (HasCallStack, MonadIO m, IsDBusServer a) 
=> a

server: A DBusServer.

-> m Bool

Returns: True if server is active, False otherwise.

Gets whether server is active.

Since: 2.26

newSync

dBusServerNewSync Source #

Arguments

:: (HasCallStack, MonadIO m, IsDBusAuthObserver a, IsCancellable b) 
=> Text

address: A D-Bus address.

-> [DBusServerFlags]

flags: Flags from the DBusServerFlags enumeration.

-> Text

guid: A D-Bus GUID.

-> Maybe a

observer: A DBusAuthObserver or Nothing.

-> Maybe b

cancellable: A Cancellable or Nothing.

-> m DBusServer

Returns: A DBusServer or Nothing if error is set. Free with objectUnref. (Can throw GError)

Creates a new D-Bus server that listens on the first address in address that works.

Once constructed, you can use dBusServerGetClientAddress to get a D-Bus address string that clients can use to connect.

Connect to the DBusServer::new-connection signal to handle incoming connections.

The returned DBusServer isn't active - you have to start it with dBusServerStart.

DBusServer is used in this [example][gdbus-peer-to-peer].

This is a synchronous failable constructor. See g_dbus_server_new() for the asynchronous version.

Since: 2.26

start

dBusServerStart Source #

=> a

server: A DBusServer.

-> m ()

stop

dBusServerStop Source #

Arguments

:: (HasCallStack, MonadIO m, IsDBusServer a) 
=> a

server: A DBusServer.

-> m () 

Stops server.

Since: 2.26

Properties

active

Whether the server is currently active.

Since: 2.26

getDBusServerActive :: (MonadIO m, IsDBusServer o) => o -> m Bool Source #

Get the value of the “active” property. When overloading is enabled, this is equivalent to

get dBusServer #active

address

The D-Bus address to listen on.

Since: 2.26

constructDBusServerAddress :: IsDBusServer o => Text -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “address” property. This is rarely needed directly, but it is used by new.

getDBusServerAddress :: (MonadIO m, IsDBusServer o) => o -> m (Maybe Text) Source #

Get the value of the “address” property. When overloading is enabled, this is equivalent to

get dBusServer #address

authenticationObserver

A DBusAuthObserver object to assist in the authentication process or Nothing.

Since: 2.26

constructDBusServerAuthenticationObserver :: (IsDBusServer o, IsDBusAuthObserver a) => a -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “authentication-observer” property. This is rarely needed directly, but it is used by new.

getDBusServerAuthenticationObserver :: (MonadIO m, IsDBusServer o) => o -> m (Maybe DBusAuthObserver) Source #

Get the value of the “authentication-observer” property. When overloading is enabled, this is equivalent to

get dBusServer #authenticationObserver

clientAddress

The D-Bus address that clients can use.

Since: 2.26

getDBusServerClientAddress :: (MonadIO m, IsDBusServer o) => o -> m Text Source #

Get the value of the “client-address” property. When overloading is enabled, this is equivalent to

get dBusServer #clientAddress

flags

Flags from the DBusServerFlags enumeration.

Since: 2.26

constructDBusServerFlags :: IsDBusServer o => [DBusServerFlags] -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “flags” property. This is rarely needed directly, but it is used by new.

getDBusServerFlags :: (MonadIO m, IsDBusServer o) => o -> m [DBusServerFlags] Source #

Get the value of the “flags” property. When overloading is enabled, this is equivalent to

get dBusServer #flags

guid

The guid of the server.

Since: 2.26

constructDBusServerGuid :: IsDBusServer o => Text -> IO (GValueConstruct o) Source #

Signals

newConnection

type C_DBusServerNewConnectionCallback = Ptr () -> Ptr DBusConnection -> Ptr () -> IO CInt Source #

Type for the callback on the (unwrapped) C side.

type DBusServerNewConnectionCallback Source #

Arguments

 = DBusConnection

connection: A DBusConnection for the new connection.

-> IO Bool

Returns: True to claim connection, False to let other handlers run.

Emitted when a new authenticated connection has been made. Use dBusConnectionGetPeerCredentials to figure out what identity (if any), was authenticated.

If you want to accept the connection, take a reference to the connection object and return True. When you are done with the connection call dBusConnectionClose and give up your reference. Note that the other peer may disconnect at any time - a typical thing to do when accepting a connection is to listen to the DBusConnection::closed signal.

If DBusServer:flags contains DBusServerFlagsRunInThread then the signal is emitted in a new thread dedicated to the connection. Otherwise the signal is emitted in the [thread-default main context][g-main-context-push-thread-default] of the thread that server was constructed in.

You are guaranteed that signal handlers for this signal runs before incoming messages on connection are processed. This means that it's suitable to call g_dbus_connection_register_object() or similar from the signal handler.

Since: 2.26

afterDBusServerNewConnection :: (IsDBusServer a, MonadIO m) => a -> DBusServerNewConnectionCallback -> m SignalHandlerId Source #

after dBusServer #newConnection callback

onDBusServerNewConnection :: (IsDBusServer a, MonadIO m) => a -> DBusServerNewConnectionCallback -> m SignalHandlerId Source #

Connect a signal handler for the “new-connection” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on dBusServer #newConnection callback
