-- t'GI.Gio.Objects.SocketAddressEnumerator.SocketAddressEnumerator' is an enumerator type for t'GI.Gio.Objects.SocketAddress.SocketAddress'
-- instances. It is returned by enumeration functions such as
-- 'GI.Gio.Interfaces.SocketConnectable.socketConnectableEnumerate', which returns a t'GI.Gio.Objects.SocketAddressEnumerator.SocketAddressEnumerator'
-- to list each t'GI.Gio.Objects.SocketAddress.SocketAddress' which could be used to connect to that
-- t'GI.Gio.Interfaces.SocketConnectable.SocketConnectable'.
-- 
-- Enumeration is typically a blocking operation, so the asynchronous methods
-- 'GI.Gio.Objects.SocketAddressEnumerator.socketAddressEnumeratorNextAsync' and
-- 'GI.Gio.Objects.SocketAddressEnumerator.socketAddressEnumeratorNextFinish' should be used where possible.
-- 
-- Each t'GI.Gio.Objects.SocketAddressEnumerator.SocketAddressEnumerator' can only be enumerated once. Once
-- 'GI.Gio.Objects.SocketAddressEnumerator.socketAddressEnumeratorNext' has returned 'P.Nothing', further
-- enumeration with that t'GI.Gio.Objects.SocketAddressEnumerator.SocketAddressEnumerator' is not possible, and it can
-- be unreffed.
