public class SocketConnectable extends Interface
Objects that describe one or more potential socket endpoints
implement `GSocketConnectable`. Callers can then use
[method@Gio.SocketConnectable.enumerate] to get a
[class@Gio.SocketAddressEnumerator] to try out each socket address in turn
until one succeeds, as shown in the sample code below.

```c
MyConnectionType *
connect_to_host (const char *hostname,
guint16 port,
GCancellable *cancellable,
GError **error)
{
MyConnection *conn = NULL;
GSocketConnectable *addr;
GSocketAddressEnumerator *enumerator;
GSocketAddress *sockaddr;
GError *conn_error = NULL;

addr = g_network_address_new (hostname, port);
enumerator = g_socket_connectable_enumerate (addr);
g_object_unref (addr);

// Try each sockaddr until we succeed. Record the first connection error,
// but not any further ones (since they'll probably be basically the same
// as the first).
while (!conn && (sockaddr = g_socket_address_enumerator_next (enumerator, cancellable, error))
{
conn = connect_to_sockaddr (sockaddr, conn_error ? NULL : &conn_error);
g_object_unref (sockaddr);
}
g_object_unref (enumerator);

if (conn)
{
if (conn_error)
{
// We couldn't connect to the first address, but we succeeded
// in connecting to a later address.
g_error_free (conn_error);
}
return conn;
}
else if (error)
{
/// Either initial lookup failed, or else the caller cancelled us.
if (conn_error)
g_error_free (conn_error);
return NULL;
}
else
{
g_error_propagate (error, conn_error);
return NULL;
}
}
```

    • getClassHandler

      public static ClassHandler getClassHandler()

    • enumerate

      public SocketAddressEnumerator enumerate()
      Creates a #GSocketAddressEnumerator for @connectable.
      Gibt zurück:
      a new #GSocketAddressEnumerator.

    • proxyEnumerate

      public SocketAddressEnumerator proxyEnumerate()
      Creates a #GSocketAddressEnumerator for @connectable that will
      return a #GProxyAddress for each of its addresses that you must connect
      to via a proxy.

      If @connectable does not implement
      g_socket_connectable_proxy_enumerate(), this will fall back to
      calling g_socket_connectable_enumerate().
      Gibt zurück:
      a new #GSocketAddressEnumerator.

    • toStr

      public Str toStr()
      Format a #GSocketConnectable as a string. This is a human-readable format for
      use in debugging output, and is not a stable serialization format. It is not
      suitable for use in user interfaces as it exposes too much information for a
      user.

      If the #GSocketConnectable implementation does not support string formatting,
      the implementation’s type name will be returned as a fallback.
