## Detailed Description

Enumerator type for objects that contain or generate SocketAddresses.

Since glibmm 2.24:

## Constructor & Destructor Documentation

## SocketAddressEnumerator()

Gio::SocketAddressEnumerator::SocketAddressEnumerator | ( | SocketAddressEnumerator&& | src | ) |

noexcept

## ~SocketAddressEnumerator()

Gio::SocketAddressEnumerator::~SocketAddressEnumerator | ( |  | ) |

override noexcept

## Member Function Documentation

## get_type()

static GType Gio::SocketAddressEnumerator::get_type | ( |  | ) |

static

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

## gobj() [1/2]

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

inline

Provides access to the underlying C GObject.

## gobj() [2/2]

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

inline

Provides access to the underlying C GObject.

## gobj_copy()

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.

## next() [1/2]

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.

## next() [2/2]

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

A next() convenience overload.

## next_async() [1/2]

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.

## next_async() [2/2]

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.

## next_finish()

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.

## operator=()

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

noexcept

## Friends And Related Function Documentation

## wrap()

Glib::RefPtr< Gio::SocketAddressEnumerator > wrap | ( | GSocketAddressEnumerator * | 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.
