Detailed Description
Job that fetches items from the Akonadi storage.
This class is used to fetch items from the Akonadi storage. Which parts of the items (e.g. headers only, attachments or all) can be specified by the ItemFetchScope.
Example:
// Fetch all items with full payload from the root collection
Akonadi.ItemFetchJob *job = new Akonadi.ItemFetchJob( Akonadi.Collection.root() );
job->fetchScope().fetchFullPayload();
if ( job->exec() ) {
Akonadi.Item.List items = job->items();
foreach( const Akonadi.Item &item, items ) {
qDebug() "Item ID:" << item.id();
}
} else {
qDebug() << "Error occurred";
}

| Akonadi.ItemFetchScope fetchScope | ( | self ) |

- The items are invalid before the result( KJob* ) signal has been emitted or if an error occurred.
| itemsReceived | ( | self, | ||
| Akonadi.Item.List | items | |||
| ) |
This signal is emitted when the items are fetched completely.
- Parameters:

items The fetched items.
- Signal syntax:
QObject.connect(source, SIGNAL("itemsReceived(const List&)"), target_slot)
| setFetchScope | ( | self, | ||
| Akonadi.ItemFetchScope | fetchScope | |||
| ) |
Sets the item fetch scope.
The ItemFetchScope controls how much of an item's data is fetched from the server, e.g. whether to fetch the full item payload or only meta data.
