Detailed Description

The QOrganizerCollectionChangeSet class provides a simple API to simplify the emission of state-change signals from QOrganizerManagerEngine implementations.

This class can be utilized by backend implementations to ensure correct emission of the QOrganizerManagerEngine::dataChanged(), QOrganizerManagerEngine::itemsAdded(), QOrganizerManagerEngine::itemsChanged() and QOrganizerManagerEngine::itemsRemoved().

See also QOrganizerManagerEngine.

void QOrganizerCollectionChangeSet::insertAddedCollection ( const QOrganizerCollectionId & addedOrganizerCollectionId )

Inserts the given collection id addedOrganizerCollectionId into the set of ids of collections which have been added to the database.

This function was introduced in Qt Mobility 1.1.

void QOrganizerCollectionChangeSet::insertAddedCollections ( const QList<QOrganizerCollectionId> & addedOrganizerCollectionIds )

Inserts each of the given collection ids addedOrganizerCollectionIds into the set of ids of collections which have been added to the database.

This function was introduced in Qt Mobility 1.1.

void QOrganizerCollectionChangeSet::insertChangedCollection ( const QOrganizerCollectionId & changedOrganizerCollectionId )

Inserts the given collection id changedOrganizerCollectionId into the set of ids of collections which have been changed to the database.
