Detailed Description

Job that fetches collections from the Akonadi storage.

This class can be used to retrieve the complete or partial collection tree from the Akonadi storage.

 using namespace Akonadi;

 // fetching all collections containing emails recursively, starting at the root collection
 CollectionFetchJob *job = new CollectionFetchJob( Collection::root(), CollectionFetchJob::Recursive, this );
 job->fetchScope().setContentMimeTypes( QStringList() << "message/rfc822" );
 connect( job, SIGNAL( collectionsReceived( const Akonadi::Collection::List& ) ),
          this, SLOT( myCollectionsReceived( const Akonadi::Collection::List& ) ) );
 connect( job, SIGNAL( result( KJob* ) ), this, SLOT( collectionFetchResult( KJob* ) ) );

Member Enumeration Documentation

enum Akonadi::CollectionFetchJob::Type

Describes the type of fetch depth.

Enumerator:
Base 

Only fetch the base collection.

FirstLevel 

Only list direct sub-collections of the base collection.

Recursive 

List all sub-collections.

Definition at line 61 of file collectionfetchjob.h.


Constructor & Destructor Documentation

Akonadi::CollectionFetchJob::CollectionFetchJob ( const Collection &  collection,
Type  type = FirstLevel,
QObject *  parent = 0 
) [explicit]

Creates a new collection fetch job.

If the given base collection has a unique identifier, this is used to identify the collection in the Akonadi server. If only a remote identifier is avaiable the collection is identified using that, given a resource search context has been specified. There two ways of doing that: by calling setResource() or globally using Akonadi::ResourceSelectJob.

Parameters:
collection The base collection for the listing.
type The type of fetch depth.
parent The parent object.
Akonadi::CollectionFetchJob::CollectionFetchJob ( const Collection::List &  collections,
QObject *  parent = 0 
) [explicit]

Creates a new collection fetch job to retrieve a list of collections.

The same rules for identifiers apply as noted in the constructor above.

Parameters:
collections A list of collections to fetch. Must not be empty.
parent The parent object.
virtual Akonadi::CollectionFetchJob::~CollectionFetchJob (  )  [virtual]

Destroys the collection fetch job.


Member Function Documentation

Collection::List Akonadi::CollectionFetchJob::collections (  )  const

Returns the list of fetched collection.

void Akonadi::CollectionFetchJob::collectionsReceived ( const Akonadi::Collection::List &  collections  )  [signal]

This signal is emitted whenever the job has received collections.

Parameters:
collections The received collections.
virtual void Akonadi::CollectionFetchJob::doHandleResponse ( const QByteArray &  tag,
const QByteArray &  data 
) [protected, virtual]

This method should be reimplemented in the concrete jobs in case you want to handle incoming data.

It will be called on received data from the backend. The default implementation does nothing.

Parameters:
tag The tag of the corresponding command, empty if this is an untagged response.
data The received data.

Reimplemented from Akonadi::Job.

virtual void Akonadi::CollectionFetchJob::doStart (  )  [protected, virtual]

This method must be reimplemented in the concrete jobs.

It will be called after the job has been started and a connection to the Akonadi backend has been established.

Implements Akonadi::Job.

CollectionFetchScope& Akonadi::CollectionFetchJob::fetchScope (  ) 

Returns the collection 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 CollectionFetchScope documentation for an example.

Returns:
a reference to the current collection fetch scope
See also:
setFetchScope() for replacing the current collection fetch scope
Since:
4.4
void Akonadi::CollectionFetchJob::includeStatistics ( bool  include = true  ) 

Include also statistics about the collections.

Since:
4.3
Deprecated:
Use CollectionFetchScope instead.
void Akonadi::CollectionFetchJob::includeUnsubscribed ( bool  include = true  ) 

Include also unsubscribed collections.

Deprecated:
Use CollectionFetchScope instead.
void Akonadi::CollectionFetchJob::setFetchScope ( const CollectionFetchScope &  fetchScope  ) 

Sets the collection fetch scope.

The CollectionFetchScope controls how much of a collection's data is fetched from the server as well as filter to select which collections to fetch.

Parameters:
fetchScope The new scope for collection fetch operations.
See also:
fetchScope()
Since:
4.4
void Akonadi::CollectionFetchJob::setResource ( const QString &  resource  ) 

Sets a resource identifier to limit collection listing to one resource.

Parameters:
resource The resource identifier.
Deprecated:
Use CollectionFetchScope instead.
