## Detailed Description

Proxy - Interface for proxy handling.

A Proxy handles connecting to a remote host via a given type of proxy server. It is implemented by the 'gio-proxy' extension point. The extensions are named after their proxy protocol name. As an example, a SOCKS5 proxy implementation can be retrieved with the name 'socks5' using the C API's function g_io_extension_point_get_extension_by_name().

Since glibmm 2.28:

## Constructor & Destructor Documentation

virtual Gio::Proxy::~Proxy | ( |  | ) | `[virtual]`

## Member Function Documentation

static void Gio::Proxy::add_interface | ( | GType | gtype_implementer | ) | `[static]`

Glib::RefPtr<IOStream> Gio::Proxy::connect | ( | const Glib::RefPtr< IOStream >& | connection,
|  | const Glib::RefPtr< const ProxyAddress >& | proxy_adress,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

Given connection to communicate with a proxy (eg, a SocketConnection that is connected to the proxy server), this does the necessary handshake to connect to proxy_address, and if required, wraps the IOStream to handle proxy payload.

Since glibmm 2.26:

Parameters:

  connection | A IOStream.
  proxy_address | A ProxyAddress.
  cancellable | A Cancellable.

Returns:
  A IOStream that will replace connection. This might be the same as connection, in which case a reference will be added.

void Gio::Proxy::connect_async | ( | const Glib::RefPtr< IOStream >& | connection,
|  | const Glib::RefPtr< const ProxyAddress >& | proxy_address,
|  | const SlotAsyncReady & | slot,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

An Asynchronous version of connect().

void Gio::Proxy::connect_async | ( | const Glib::RefPtr< IOStream >& | connection,
|  | const Glib::RefPtr< const ProxyAddress >& | proxy_address,
|  | const SlotAsyncReady & | slot
| ) |  |

An Asynchronous version of connect().

Glib::RefPtr<IOStream> Gio::Proxy::connect_finish | ( | const Glib::RefPtr< AsyncResult >& | result | ) |

See g_proxy_connect().

Since glibmm 2.26:

Parameters:

  result | A AsyncRetult.

Returns:
  A IOStream.

static Glib::RefPtr<Proxy> Gio::Proxy::get_default_for_protocol | ( | const Glib::ustring& | protocol | ) | `[static]`

Lookup "gio-proxy" extension point for a proxy implementation that supports specified protocol.

Since glibmm 2.26:

Parameters:

  protocol | The proxy protocol name (e.g. http, socks, etc).

Returns:
  Return a Proxy or `0` if protocol is not supported.

GProxy* Gio::Proxy::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

const GProxy* Gio::Proxy::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

bool Gio::Proxy::supports_hostname | ( |  | ) | const

Some proxy protocols expect to be passed a hostname, which they will resolve to an IP address themselves.

Others, like SOCKS4, do not allow this. This function will return `false` if proxy is implementing such a protocol. When `false` is returned, the caller should resolve the destination hostname first, and then pass a ProxyAddress containing the stringified IP address to g_proxy_connect() or g_proxy_connect_async().

Since glibmm 2.26:

Returns:
  `true` if hostname resolution is supported.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::Proxy > wrap | ( | GProxy * | 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.
