Member Function Documentation

static GType Gio::SocketAddressEnumerator::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

GSocketAddressEnumerator* Gio::SocketAddressEnumerator::gobj ( )

inline

Provides access to the underlying C GObject.

const GSocketAddressEnumerator* Gio::SocketAddressEnumerator::gobj ( ) const

inline

Provides access to the underlying C GObject.

GSocketAddressEnumerator* Gio::SocketAddressEnumerator::gobj_copy ( )

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

Glib::RefPtr<SocketAddress> Gio::SocketAddressEnumerator::next ( const Glib::RefPtr< Cancellable >& cancellable )

Retrieves the next SocketAddress from enumerator.

Note that this may block for some amount of time. (Eg, a NetworkAddress may need to do a DNS lookup before it can return an address.) Use g_socket_address_enumerator_next_async() if you need to avoid blocking.

If enumerator is expected to yield addresses, but for some reason is unable to (eg, because of a DNS error), then the first call to g_socket_address_enumerator_next() will return an appropriate error in * error. However, if the first call to g_socket_address_enumerator_next() succeeds, then any further internal errors (other than cancellable being triggered) will be ignored.

Parameters

cancellable Optional Cancellable object, nullptr to ignore.

Returns: A SocketAddress (owned by the caller), or nullptr on error (in which case* error will be set) or if there are no more addresses.

Exceptions

Glib::Error

Glib::RefPtr<SocketAddress> Gio::SocketAddressEnumerator::next ( )

A next() convenience overload.

void Gio::SocketAddressEnumerator::next_async	(	const Glib::RefPtr< Cancellable >&	cancellable,
		const SlotAsyncReady &	slot
	)

Asynchronously retrieves the next SocketAddress from the enumerator and then calls slot, which must call next_finish() to get the result.

Parameters

cancellable	A Cancellable object which can be used to cancel the operation.
slot	A callback slot to call after the resolution completes.

void Gio::SocketAddressEnumerator::next_async ( const SlotAsyncReady & slot )

Asynchronously retrieves the next SocketAddress from the enumerator and then calls slot, which must call next_finish() to get the result.

Parameters

slot	A callback slot to call after the resolution completes.

Glib::RefPtr<SocketAddress> Gio::SocketAddressEnumerator::next_finish ( const Glib::RefPtr< AsyncResult >& result )

Retrieves the result of a completed call to g_socket_address_enumerator_next_async().

See g_socket_address_enumerator_next() for more information about error handling.

Parameters

result A AsyncResult.

Returns: A SocketAddress (owned by the caller), or nullptr on error (in which case* error will be set) or if there are no more addresses.

Exceptions

Glib::Error

SocketAddressEnumerator& Gio::SocketAddressEnumerator::operator= ( SocketAddressEnumerator&& src )

noexcept

Friends And Related Function Documentation

Glib::RefPtr< Gio::SocketAddressEnumerator > wrap	(	GSocketAddressEnumerator *	object,
		bool	take_copy = `false`
	)

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.
