Detailed Description

ProxyResolver - Asynchronous and cancellable network proxy resolver.

ProxyResolver provides synchronous and asynchronous network proxy resolution. ProxyResolver is used within ClientSocket through the method Gio::SocketConnectable::proxy_enumerate().

Since glibmm 2.28:

Member Function Documentation

static void Gio::ProxyResolver::add_interface ( GType  gtype_implementer) [static]

Gets the default ProxyResolver for the system.

Since glibmm 2.26:
Returns:
The default ProxyResolver.
GProxyResolver* Gio::ProxyResolver::gobj ( ) [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

const GProxyResolver* Gio::ProxyResolver::gobj ( ) const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Checks if resolver can be used on this system.

(This is used internally; g_proxy_resolver_get_default() will only return a proxy resolver that returns true for this method.)

Since glibmm 2.26:
Returns:
true if resolver is supported.

Looks into the system proxy configuration to determine what proxy, if any, to use to connect to uri.

The returned proxy URIs are of the form <protocol>://[user[:password]@]host:port or direct://, where <protocol> could be http, rtsp, socks or other proxying protocol.

If you don't know what network protocol is being used on the socket, you should use none as the URI protocol. In this case, the resolver might still return a generic proxy type (such as SOCKS), but would not return protocol-specific proxy types (such as http).

direct:// is used when no proxy is needed. Direct connection should not be attempted unless it is part of the returned array of proxies.

Since glibmm 2.26:
Parameters:
uriA URI representing the destination to connect to.
cancellableA Cancellable, or 0.
Returns:
A 0-terminated array of proxy URIs. Must be freed with Glib::strfreev().

Looks into the system proxy configuration to determine what proxy, if any, to use to connect to uri.

The returned proxy URIs are of the form <protocol>://[user[:password]@]host:port or direct://, where <protocol> could be http, rtsp, socks or other proxying protocol.

If you don't know what network protocol is being used on the socket, you should use none as the URI protocol. In this case, the resolver might still return a generic proxy type (such as SOCKS), but would not return protocol-specific proxy types (such as http).

direct:// is used when no proxy is needed. Direct connection should not be attempted unless it is part of the returned array of proxies.

Parameters:
uria URI representing the destination to connect to.
void Gio::ProxyResolver::lookup_async ( const Glib::ustring uri,
const SlotAsyncReady slot,
const Glib::RefPtr< Cancellable >&  cancellable 
)

Asynchronous lookup of proxy.

See lookup() for more details.

Parameters:
uria URI representing the destination to connect to.
slotA callback slot to call after the resolution completes.
cancellableA Cancellable object which can be used to cancel the operation.
void Gio::ProxyResolver::lookup_async ( const Glib::ustring uri,
const SlotAsyncReady slot 
)

Asynchronous lookup of proxy.

See lookup() for more details.

Parameters:
uria URI representing the destination to connect to.
slotA callback slot to call after the resolution completes.

Call this function to obtain the array of proxy URIs when g_proxy_resolver_lookup_async() is complete.

See g_proxy_resolver_lookup() for more details.

Since glibmm 2.26:
Parameters:
resultThe result passed to your AsyncReadyCallback.
Returns:
A 0-terminated array of proxy URIs. Must be freed with Glib::strfreev().
