Signals |
void | accountCreated (Accounts::AccountId id) |
| The signal is emitted when new account is created.
|
void | accountRemoved (Accounts::AccountId id) |
| The signal is emitted when existing account is removed.
|
void | accountUpdated (Accounts::AccountId id) |
| The signal is emitted when any account property for a particular service is updated.
|
void | enabledEvent (Accounts::AccountId id) |
| If the manager has been created with serviceType, this signal will be emitted when an account (identified by AccountId) has been modified in such a way that the application might be interested to start/stop using it: the "enabled" flag on the account or in some service supported by the account and matching the AgManager::serviceType have changed.

Constructor & Destructor Documentation
Accounts::Manager::Manager |
( |
QObject * |
parent = 0 |
) |
|
Constructor.
Users should check for manager->lastError() to check if manager construction was fully succesful, other than just checking for if manager != NULL
Accounts::Manager::Manager |
( |
const QString & |
serviceType, |
|
|
QObject * |
parent = 0 | |
|
) |
| | |
Constructs a manager initialized with service type.
This constructor should be used when there is an interest for just one service type. Such a manager has influence on some class methods. When listing the accounts and services only the ones supporting the given service type will be returned. Also the creating account with this manager will affect the acccount class method for listing services in same manner. The signal enabledEvent() will be emitted only when manager is created with this constructor. Users should check for manager->lastError() to check if manager construction was fully succesful, other than just checking for if manager != NULL

Member Function Documentation
bool Accounts::Manager::abortOnTimeout |
( |
|
) |
const |
- Returns:
- Whether the application will be aborted when a database timeout occurs.
Loads an account from the database.
- Parameters:
-
| id | Id of the account to be retrieved. |
- Returns:
- Requested account or NULL if not found. If NULL is returned, call lastError() to find out why.
The signal is emitted when new account is created.
- Parameters:
-
AccountIdList Accounts::Manager::accountList |
( |
const QString & |
serviceType = QString::null |
) |
const |
Lists the accounts which support the requested service.
- Parameters:
-
| serviceType | Type of service that returned accounts must support. If not given and the manager is not constructed with service type, all accounts are returned. |
- Returns:
- List of account IDs.
AccountIdList Accounts::Manager::accountListEnabled |
( |
const QString & |
serviceType = QString::null |
) |
const |
Lists the enabled accounts which support the requested service that also must be enabled.
- Parameters:
-
| serviceType | Type of service that returned accounts must support. If not given and the manager is not constructed with service type, all enabled accounts are returned. |
- Returns:
- List of account IDs.
The signal is emitted when existing account is removed.
- Parameters:
-
The signal is emitted when any account property for a particular service is updated.
To receive this notification user has to create accounts manager using Manager(const QString &serviceType, QObject *parent) constructor. Update notification is only emitted when manager is created for particular type of service.
- Parameters:
-
Account* Accounts::Manager::createAccount |
( |
const QString & |
providerName |
) |
|
Creates a new account.
- Parameters:
-
| providerName | Name of account provider. |
- Returns:
- Created account or NULL if some error occurs.
If the manager has been created with serviceType, this signal will be emitted when an account (identified by AccountId) has been modified in such a way that the application might be interested to start/stop using it: the "enabled" flag on the account or in some service supported by the account and matching the AgManager::serviceType have changed.
In practice, this signal might be emitted more often than when strictly needed; applications must call Account::enabledServices() to get the current state.
- Parameters:
-
Error Accounts::Manager::lastError |
( |
|
) |
const |
Gets the last error.
Not all operations set/reset the error; see the individual methods' documentation to see if they set the last error or not. Call this method right after an account operation has failed; if no error occurred, the result of this method are undefined.
- Returns:
- The last error.
Provider* Accounts::Manager::provider |
( |
const QString & |
providerName |
) |
const |
Gets an object representing a provider.
- Parameters:
-
| providerName | Name of provider to get. |
- Returns:
- Requested provider or NULL if not found.
Gets a provider list.
- Returns:
- List of registered providers.
Service* Accounts::Manager::service |
( |
const QString & |
serviceName |
) |
const |
Gets an object representing a service.
- Parameters:
-
| serviceName | Name of service to get. |
- Returns:
- Requested service or NULL if not found.
ServiceList Accounts::Manager::serviceList |
( |
const QString & |
serviceType = QString::null |
) |
const |
Gets the service list.
If the manager is constructed with given service type only the services which supports the service type will be returned.
- Parameters:
-
| serviceType | Type of services to be listed. If not given and the manager is not constructed with service type, all services are listed. |
- Returns:
- List of Service objects.
QString Accounts::Manager::serviceType |
( |
|
) |
const |
Gets the service type if given in manager constructor.
- Returns:
- Service type or NULL if not given.
ServiceType* Accounts::Manager::serviceType |
( |
const QString & |
name |
) |
const |
Gets an object representing a service type.
- Parameters:
-
| name | Name of service type to load. |
- Returns:
- Requested service type or NULL if not found.
void Accounts::Manager::setAbortOnTimeout |
( |
bool |
abort |
) |
|
Sets whether to abort the application when a database timeout occurs.
By default the library does not abort the application.
void Accounts::Manager::setTimeout |
( |
quint32 |
timeout |
) |
|
Sets the timeout for database operations.
- Parameters:
-
| timeout | The new timeout in milliseconds. |
This tells the library how long it is allowed to block while waiting for a locked DB to become accessible. Higher values mean a higher chance of successful reads, but also mean that the execution might be blocked for a longer time. The default is 5 seconds.
quint32 Accounts::Manager::timeout |
( |
|
) |
|
Gets the database timeout.
- Returns:
- The timeout (in milliseconds) for database operations.
