| \class QNetworkConfiguration |
| \obsolete |
| |
| \brief The QNetworkConfiguration class provides an abstraction of one or more access point configurations. |
| |
| \since 4.7 |
| |
| \inmodule QtNetwork |
| \ingroup network |
| \ingroup shared |
| |
| QNetworkConfiguration encapsulates a single access point or service network. |
| In most cases a single access point configuration can be mapped to one network |
| interface. However a single network interface may not always map to only one |
| access point configuration. Multiple configurations for the same |
| network device may enable multiple access points. An example |
| device that could exhibit such a configuration might be a |
| Smartphone which allows the user to manage multiple WLAN |
| configurations while the device itself has only one WLAN network device. |
| |
| The QNetworkConfiguration also supports the concept of service networks. |
| This concept allows the grouping of multiple access point configurations |
| into one entity. Such a group is called service network and can be |
| beneficial in cases whereby a network session to a |
| particular destination network is required (e.g. a company network). |
| When using a service network the user doesn't usually care which one of the |
| connectivity options is chosen (e.g. corporate WLAN or VPN via GPRS) |
| as long as he can reach the company's target server. Depending |
| on the current position and time some of the access points that make |
| up the service network may not even be available. Furthermore |
| automated access point roaming can be enabled which enables the device |
| to change the network interface configuration dynamically while maintaining |
| the applications connection to the target network. It allows adaption |
| to the changing environment and may enable optimization with regards to |
| cost, speed or other network parameters. |
| |
| Special configurations of type UserChoice provide a placeholder configuration which is |
| resolved to an actual network configuration by the platform when a |
| \l {QNetworkSession}{session} is \l {QNetworkSession::open()}{opened}. Not all platforms |
| support the concept of a user choice configuration. |
| |
| \section1 Configuration States |
| |
| The list of available configurations can be obtained via |
| QNetworkConfigurationManager::allConfigurations(). A configuration can have |
| multiple states. The \l Defined configuration state indicates that the configuration |
| is stored on the device. However the configuration is not yet ready to be activated |
| as e.g. a WLAN may not be available at the current time. |
| |
| The \l Discovered state implies that the configuration is \l Defined and |
| the outside conditions are such that the configuration can be used immediately |
| to open a new network session. An example of such an outside condition may be |
| that the Ethernet cable is actually connected to the device or that the WLAN |
| with the specified SSID is in range. |
| |
| The \l Active state implies that the configuration is \l Discovered. A configuration |
| in this state is currently being used by an application. The underlying network |
| interface has a valid IP configuration and can transfer IP packets between the |
| device and the target network. |
| |
| The \l Undefined state indicates that the system has knowledge of possible target |
| networks but cannot actually use that knowledge to connect to it. An example |
| for such a state could be an encrypted WLAN that has been discovered |
| but the user hasn't actually saved a configuration including the required password |
| which would allow the device to connect to it. |
| |
| Depending on the type of configuration some states are transient in nature. A GPRS/UMTS |
| connection may almost always be \l Discovered if the GSM/UMTS network is available. |
| However if the GSM/UMTS network loses the connection the associated configuration may change its state |
| from \l Discovered to \l Defined as well. A similar use case might be triggered by |
| WLAN availability. QNetworkConfigurationManager::updateConfigurations() can be used to |
| manually trigger updates of states. Note that some platforms do not require such updates |
| as they implicitly change the state once it has been discovered. If the state of a |
| configuration changes all related QNetworkConfiguration instances change their state automatically. |

| /*! |
| \enum QNetworkConfiguration::Type |
| |
| This enum describes the type of configuration. |
| |
| \value InternetAccessPoint The configuration specifies the details for a single access point. |
| Note that configurations of type InternetAccessPoint may be part |
| of other QNetworkConfigurations of type ServiceNetwork. |
| \value ServiceNetwork The configuration is based on a group of QNetworkConfigurations of |
| type InternetAccessPoint. All group members can reach the same |
| target network. This type of configuration is a mandatory |
| requirement for roaming enabled network sessions. On some |
| platforms this form of configuration may also be called Service |
| Network Access Point (SNAP). |
| \value UserChoice The configuration is a placeholder which will be resolved to an |
| actual configuration by the platform when a session is opened. Depending |
| on the platform the selection may generate a popup dialog asking the user |
| for his preferred choice. |
| \value Invalid The configuration is invalid. |
| */ |
| |
| /*! |
| \enum QNetworkConfiguration::StateFlag |
| |
| Specifies the configuration states. |
| |
| \value Undefined This state is used for transient configurations such as newly discovered |
| WLANs for which the user has not actually created a configuration yet. |
| \value Defined Defined configurations are known to the system but are not immediately |
| usable (e.g. a configured WLAN is not within range or the Ethernet cable |
| is currently not plugged into the machine). |
| \value Discovered A discovered configuration can be immediately used to create a new |
| QNetworkSession. An example of a discovered configuration could be a WLAN |
| which is within in range. If the device moves out of range the discovered |
| flag is dropped. A second example is a GPRS configuration which generally |
| remains discovered for as long as the device has network coverage. A |
| configuration that has this state is also in state |
| QNetworkConfiguration::Defined. If the configuration is a service network |
| this flag is set if at least one of the underlying access points |
| configurations has the Discovered state. |
| \value Active The configuration is currently used by an open network session |
| (see \l QNetworkSession::isOpen()). However this does not mean that the |
| current process is the entity that created the open session. It merely |
| indicates that if a new QNetworkSession were to be constructed based on |
| this configuration \l QNetworkSession::state() would return |
| \l QNetworkSession::Connected. This state implies the |
| QNetworkConfiguration::Discovered state. |

| \value PrivatePurpose The configuration is suitable to access a private network such as an office Intranet. |
| \value ServiceSpecificPurpose The configuration can be used for operator specific services (e.g. |
| receiving MMS messages or content streaming). |

| \enum QNetworkConfiguration::BearerType |
| |
| Specifies the type of bearer used by a configuration. |
| |
| \value BearerUnknown The type of bearer is unknown or unspecified. The bearerTypeName() |
| function may return additional information. |
| \value BearerEthernet The configuration is for an Ethernet interfaces. |
| \value BearerWLAN The configuration is for a Wireless LAN interface. |
| \value Bearer2G The configuration is for a CSD, GPRS, HSCSD, EDGE or cdmaOne interface. |
| \value Bearer3G The configuration is for a 3G interface. |

| \value BearerCDMA2000 The configuration is for CDMA interface. |
