Detailed Description

Job that modifies a collection in the Akonadi storage.

This job modifies the properties of an existing collection.

Akonadi::Collection collection = ...
 
auto job = new Akonadi::CollectionModifyJob(collection);
connect(job, &KJob::result, this, &MyClass::modifyResult);

If the collection has attributes, it is recommended only to supply values for any attributes whose values are to be updated. This will help to avoid potential clashes with other resources or applications which may happen to update the collection simultaneously. To avoid supplying attribute values which are not needed, create a new instance of the collection and explicitly set attributes to be updated, e.g.

// Update the 'MyAttribute' attribute of 'collection'.
Akonadi::Collection c(collection.id());
auto attribute = c.attribute<MyAttribute>(Collection::AddIfMissing);
if (collection.hasAttribute<MyAttribute>()) {
    *attribute = *collection.attribute<MyAttribute>();
}
// Update the value of 'attribute' ...
auto job = new Akonadi::CollectionModifyJob(c);
connect(job, &KJob::result, this, &MyClass::modifyResult);

To update only the collection, and not change any attributes:

// Update the cache policy for 'collection' to 'newPolicy'.
Akonadi::Collection c(collection.id());
c.setCachePolicy(newPolicy);
auto job = new Akonadi::CollectionModifyJob(c);
connect(job, &KJob::result, this, &MyClass::modifyResult);

Constructor & Destructor Documentation

CollectionModifyJob()

CollectionModifyJob::CollectionModifyJob ( const Collection & collection, QObject * parent = nullptr )

explicit

Creates a new collection modify job for the given collection.

The collection can be identified either by its unique identifier or its remote identifier. Since the remote identifier is not necessarily globally unique, identification by remote identifier only works inside a resource context (that is from within ResourceBase) and is therefore limited to one resource.

Parameters

collection	The collection to modify.
parent	The parent object.

Definition at line 35 of file collectionmodifyjob.cpp.

~CollectionModifyJob()

CollectionModifyJob::~CollectionModifyJob ( )

override

Destroys the collection modify job.

Definition at line 42 of file collectionmodifyjob.cpp.

Member Function Documentation

collection()

Collection CollectionModifyJob::collection ( ) const

nodiscard

Returns the modified collection.

Since

4.4

Definition at line 122 of file collectionmodifyjob.cpp.

doHandleResponse()

bool CollectionModifyJob::doHandleResponse ( qint64 tag, const Protocol::CommandPtr & response )

overrideprotectedvirtual

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.
response	The received response

Returns

Implementations should return true if the last response was processed and the job can emit result. Return false if more responses from server are expected.

Reimplemented from Akonadi::Job.

Definition at line 110 of file collectionmodifyjob.cpp.

doStart()

void CollectionModifyJob::doStart ( )

overrideprotectedvirtual

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.
