class Gio::SocketConnection

Overview

#GSocketConnection is a #GIOStream for a connected socket. They can be created either by #GSocketClient when connecting to a host, or by #GSocketListener when accepting a new client.

The type of the #GSocketConnection object returned from these calls depends on the type of the underlying socket that is in use. For instance, for a TCP/IP connection it will be a #GTcpConnection.

Choosing what type of object to construct is done with the socket connection factory, and it is possible for 3rd parties to register custom socket connection types for specific combination of socket family/type/protocol using g_socket_connection_factory_register_type().

To close a #GSocketConnection, use g_io_stream_close(). Closing both substreams of the #GIOStream separately will not close the underlying #GSocket.

Constructor Detail

def self.new #

Initialize a new SocketConnection.


def self.new(*, closed : Bool? = nil, input_stream : Gio::InputStream? = nil, output_stream : Gio::OutputStream? = nil, socket : Gio::Socket? = nil) #

Class Method Detail

def self.factory_lookup_type(family : Gio::SocketFamily, type : Gio::SocketType, protocol_id : Int32) : UInt64 #

Looks up the #GType to be used when creating socket connections on sockets with the specified @family, @type and @protocol_id.

If no type is registered, the #GSocketConnection base type is returned.


def self.factory_register_type(g_type : UInt64, family : Gio::SocketFamily, type : Gio::SocketType, protocol : Int32) : Nil #

Looks up the #GType to be used when creating socket connections on sockets with the specified @family, @type and @protocol.

If no type is registered, the #GSocketConnection base type is returned.


def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def connect(address : Gio::SocketAddress, cancellable : Gio::Cancellable?) : Bool #

Connect @connection to the specified remote address.


def connect_async(address : Gio::SocketAddress, cancellable : Gio::Cancellable?, callback : Gio::AsyncReadyCallback?, user_data : Pointer(Void)?) : Nil #

Asynchronously connect @connection to the specified remote address.

This clears the #GSocket:blocking flag on @connection's underlying socket if it is currently set.

Use g_socket_connection_connect_finish() to retrieve the result.


def connect_finish(result : Gio::AsyncResult) : Bool #

Gets the result of a g_socket_connection_connect_async() call.


def is_connected : Bool #

Checks if @connection is connected. This is equivalent to calling g_socket_is_connected() on @connection's underlying #GSocket.


def local_address : Gio::SocketAddress #

Try to get the local address of a socket connection.


def remote_address : Gio::SocketAddress #

Try to get the remote address of a socket connection.

Since GLib 2.40, when used with g_socket_client_connect() or g_socket_client_connect_async(), during emission of %G_SOCKET_CLIENT_CONNECTING, this function will return the remote address that will be used for the connection. This allows applications to print e.g. "Connecting to example.com (10.42.77.3)...".


def socket : Gio::Socket #

Gets the underlying #GSocket object of the connection. This can be useful if you want to do something unusual on it not supported by the #GSocketConnection APIs.


def socket=(value : Gio::Socket?) : Gio::Socket? #
