Detailed Description

Job that fetches all items of a collection recursive.

This job takes a collection as argument and returns a list of all items that are part of the passed collection and its child collections. The items to fetch can be filtered by mime types and the parts of the items that shall be fetched can be specified via an ItemFetchScope.

Example:

// Assume the following Akonadi storage tree structure:
//
// Root Collection
// |
// +- Contacts
// |  |
// |  +- Private
// |  |
// |  `- Business
// |
// `- Events
//
// Collection 'Contacts' has the ID 15, then the following code
// returns all contact items from 'Contacts', 'Private' and 'Business'.
 
const Akonadi::Collection contactsCollection( 15 );
const QStringList mimeTypes = QStringList() << KContacts::Addressee::mimeType();
 
Akonadi::RecursiveItemFetchJob *job = new Akonadi::RecursiveItemFetchJob( contactsCollection, mimeTypes );
job->fetchScope().fetchFullPayload();
connect( job, SIGNAL(result(KJob*)), this, SLOT(fetchResult(KJob*)) );
 
job->start();
 
...
 
MyClass::fetchResult( KJob *job )
{
  Akonadi::RecursiveItemFetchJob *fetchJob = qobject_cast<Akonadi::RecursiveItemFetchJob*>( job );
  const Akonadi::Item::List items = fetchJob->items();
  // do something with the items
}

Constructor & Destructor Documentation

RecursiveItemFetchJob()

RecursiveItemFetchJob::RecursiveItemFetchJob ( const Akonadi::Collection & collection, const QStringList & mimeTypes, QObject * parent = nullptr )

explicit

Creates a new recursive item fetch job.

Parameters

collection	The collection that shall be fetched recursive.
mimeTypes	The list of mime types that will be used for filtering.
parent	The parent object.

Definition at line 83 of file recursiveitemfetchjob.cpp.

~RecursiveItemFetchJob()

RecursiveItemFetchJob::~RecursiveItemFetchJob ( )

overridedefault

Destroys the recursive item fetch job.

Member Function Documentation

fetchScope()

ItemFetchScope & RecursiveItemFetchJob::fetchScope

(

)

Returns the item fetch scope.

Since this returns a reference it can be used to conveniently modify the current scope in-place, i.e. by calling a method on the returned reference without storing it in a local variable. See the ItemFetchScope documentation for an example.

Returns

a reference to the current item fetch scope

See also

setFetchScope() for replacing the current item fetch scope

Definition at line 96 of file recursiveitemfetchjob.cpp.

items()

Akonadi::Item::List RecursiveItemFetchJob::items ( ) const

nodiscard

Returns the list of fetched items.

Definition at line 114 of file recursiveitemfetchjob.cpp.

setFetchScope()

void RecursiveItemFetchJob::setFetchScope

(

const 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.

Parameters

fetchScope

The new scope for item fetch operations.

See also

fetchScope()

Definition at line 91 of file recursiveitemfetchjob.cpp.

start()

void RecursiveItemFetchJob::start ( )

overridevirtual

Starts the recursive item fetch job.

Implements KJob.
