## Detailed Description

Account settings for a specific service.

The AccountService class provides access to the account settings for a specific service type. It is meant to be easier to use than the Account class because it hides the complexity of the account structure and gives access to only the limited subset of account settings which are relevant to a service.

To get an AccountService one can use the Manager methods accountServices() or enabledAccountServices(), which both return a QList of account services. Note that if the Manager was instantiated for a specific service type, these lists will contain only those account services matching that service type. The AccountService can also be instantiated with its AccountService(Account *account, Service *service) constructor: this is useful if one already has an Account instance.

This is intended to be a convenient wrapper over the accounts settings specific for a service; as such, it doesn't offer all the editing possibilities offered by the Account class, such as enabling the service itself: these operations should ideally not be performed by consumer applications, but by the account editing UI only.

Example code:

// Instantiate an account manager interested in e-mail services only.
Accounts::Manager *manager = new Accounts::Manager("e-mail");
// Get the list of enabled AccountService objects of type e-mail.
Accounts::AccountServiceList services = manager->enabledAccountServices();
// Loop through the account services and do something useful with them.
foreach (Accounts::AccountService service, services) {
QString server = service.value("pop3/hostname").toString();
int port = service.value("pop3/port").toInt();
// Suppose that the e-mail address is stored in the global account
// settings; let's get it from there:
QString fromAddress = service.account()->valueAsString("username");
...
}

Note
  User applications (with the notable exception of the accounts editing application) should never use account services which are not enabled, and should stop using an account when the account service becomes disabled. The latter can be done by connecting to the changed() signal and checking if isEnabled() still returns true.
  Note that if the account gets deleted, it will always get disabled first; so, there is no need to connect to the Account::removed() signal; one can just monitor the changed() signal from the AccountService objects.

AccountService | ( | Account * | account,
|  | const Service & | service
| ) |  |
| explicit

Constructor.

Parameters

  account | An Account.
  service | A Service supported by the account.

Definition at line 179 of file account-service.cpp.

AccountService | ( | Account * | account,
|  | const Service & | service,
|  | QObject * | parent
| ) |  |
| explicit

Constructor.

Parameters

  account | An Account.
  service | A Service supported by the account.
  parent | The parent object.

Definition at line 191 of file account-service.cpp.

## Member Function Documentation

AuthData authData | ( |  | ) | const

Read the authentication data stored in the account (merging the service-specific settings with the global account settings).

The method and mechanism are read from the "auth/method" and "auth/mechanism" keys, respectively. The authentication parameters are found under the "auth/<method>/<mechanism>/" group.

Returns
  an AuthData object, describing the authentication settings.

Definition at line 501 of file account-service.cpp.

void beginGroup | ( | const QString & | prefix | ) |

Enter a group.

This method never fails.

Parameters

  prefix |

Definition at line 271 of file account-service.cpp.

changed | ( |  | ) |
| signal

Emitted when some setting has changed on the account service.

You can use the changedFields() method to retrieve the list of the settings which have changed.

QStringList changedFields | ( |  | ) | const

This method should be called only in the context of a handler of the AccountService::changed() signal, and can be used to retrieve the set of changes.

Returns
  a QStringList of the keys which have changed.

Definition at line 471 of file account-service.cpp.

void clear | ( |  | ) |

Remove all the keys.

See also
  remove(const QString &key)

Definition at line 316 of file account-service.cpp.

bool contains | ( | const QString & | key | ) | const

Check whether the given key is in the current group.

Parameters

  key | The key name of the setting.

Definition at line 331 of file account-service.cpp.

References AccountService::childKeys().

bool enabled | ( |  | ) | const

Check whether the account service is enabled.

Note
  this is just a wrapper of isEnabled

See also
  isEnabled()

Deprecated:
  use isEnabled instead

Definition at line 231 of file account-service.cpp.

References AccountService::isEnabled().

void remove | ( | const QString & | key | ) |

Remove the given key.

If the key is the empty string, all keys in the current group are removed.

Parameters

  key | The key name of the setting.

Definition at line 363 of file account-service.cpp.

References AccountService::allKeys().

Service service | ( |  | ) | const

Return the Service.

Do not delete this object explicitly.

Definition at line 218 of file account-service.cpp.

void setValue | ( | const QString & | key,
|  | const QVariant & | value
| ) |  |

Change the value of an account setting.

Parameters

  key | The name of the setting.
  value | The new value of the setting.

Definition at line 391 of file account-service.cpp.

QVariant value | ( | const QString & | key,
|  | const QVariant & | defaultValue,
|  | SettingSource * | source = `0`
| ) |  | const

Retrieves the value of an account setting, as a QVariant.

Parameters

  key | The key whose value must be retrieved.
  defaultValue | Value returned if the key is unset.
  source | Indicates whether the value comes from the account, the service template or was unset.

Returns
  The value associated to key.

This method operates on the currently selected service.

QVariant value | ( | const QString & | key,
|  | SettingSource * | source = `0`
| ) |  | const

Retrieves the value of an account setting.

Parameters

  key | The key whose value must be retrieved
  source | Indicates whether the value comes from the account, the service template or was unset.

Returns the value of the setting, or an invalid QVariant if unset.
