Constructor & Destructor Documentation

Manager ( QObject parent = 0 )

Constructor.

Users should check for manager->lastError() to check if manager construction was fully succesful.

Definition at line 146 of file manager.cpp.

References Error::DatabaseLocked.

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 lastError() to check if manager construction was fully succesful.

Manager	(	Options	options,
		QObject	parent = `0`
	)

Constructor, allowing option flags to be specified.

Users should check for lastError() to check if manager construction was fully succesful.

Member Function Documentation

bool abortOnTimeout ( ) const

Returns: Whether the application will be aborted when a database timeout occurs.

Definition at line 523 of file manager.cpp.

Account * account ( const AccountId & id ) const

Loads an account from the database.

Parameters

id	Id of the account to be retrieved.

Returns: Requested account or 0 if not found. If 0 is returned, call lastError() to find out why.

Attention: The objects returned by this method are shared, meaning that calling this method twice with the same id will return the same object. It is recommended that clients do not destroy the objects returned by this method, if there's the possibility that they are still being used in other parts of the application.

Definition at line 245 of file manager.cpp.

accountCreated ( Accounts::AccountId id )

signal

The signal is emitted when new account is created.

Parameters

id	Identifier of the Account

AccountIdList 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.

Definition at line 266 of file manager.cpp.

AccountIdList 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.

Definition at line 301 of file manager.cpp.

accountRemoved ( Accounts::AccountId id )

signal

The signal is emitted when existing account is removed.

Parameters

id	Identifier of the Account

accountUpdated ( Accounts::AccountId id )

signal

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

id	Identifier of the Account

Application application ( const QString & applicationName ) const

Get an object representing an application.

Parameters

applicationName Name of the application to load.

Returns: The requested Application, or an invalid Application object if not found.

Definition at line 448 of file manager.cpp.

Referenced by Manager::applicationList().

ApplicationList applicationList ( const Service & service ) const

List the registered applications which support the given service.

Parameters

service The service to be supported.

Returns: A list of Application objects.

Definition at line 462 of file manager.cpp.

References Manager::application().

Account * createAccount ( const QString & providerName )

Creates a new account.

Parameters

providerName Name of account provider.

Returns: Created account or NULL if some error occurs.

Definition at line 331 of file manager.cpp.

enabledEvent ( Accounts::AccountId id )

signal

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.

Note: In practice, this signal might be emitted more often than when strictly needed; applications must call Account::enabledServices() to get the current state.

Parameters

id	identifier of the Account

Error 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.

Definition at line 554 of file manager.cpp.

Manager::Options options ( ) const

Returns: Configuration options for this object.

Definition at line 531 of file manager.cpp.

References Manager::DisableNotifications.

Provider 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.

Definition at line 392 of file manager.cpp.

Referenced by Manager::providerList().

ProviderList providerList ( ) const

Gets a provider list.

Returns: List of registered providers.

Definition at line 406 of file manager.cpp.

References Manager::provider().

Service service ( const QString & serviceName ) const

Gets an object representing a service.

Parameters

serviceName Name of service to get.

Returns: The requested service or an invalid service if not found.

Definition at line 342 of file manager.cpp.

Referenced by Manager::serviceList().

ServiceList 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.

Definition at line 360 of file manager.cpp.

References Manager::service().

ServiceType 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.

Definition at line 433 of file manager.cpp.

QString serviceType ( ) const

Gets the service type if given in manager constructor.

Returns: Service type or NULL if not given.

Definition at line 482 of file manager.cpp.

void setAbortOnTimeout ( bool abort )

Sets whether to abort the application when a database timeout occurs.

By default the library does not abort the application.

Definition at line 514 of file manager.cpp.

void 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.

Definition at line 496 of file manager.cpp.

quint32 timeout ( )

Gets the database timeout.

Returns: The timeout (in milliseconds) for database operations.

Definition at line 505 of file manager.cpp.
