The QOrganizerItemChangeSet class provides a simple API to simplify the emission of state-change signals from QOrganizerManagerEngine implementations.
This class can be utilised by backend implementations to ensure correct emission of the QOrganizerManagerEngine::dataChanged(), QOrganizerManagerEngine::itemsAdded(), QOrganizerManagerEngine::itemsChanged() and QOrganizerManagerEngine::itemsRemoved().
See also QOrganizerManagerEngine.
Constructs a new change set
Constructs a copy of the other change set
Frees the memory used by this change set
Returns the set of ids of organizer items which have been added to the database.
Returns the set of ids of organizer items which have been changed in the database.
Clears the set of ids of organizer items which have been added to the database
Clears all flags and sets of ids in this change set
Clears the set of ids of organizer items which have been changed to the database
Clears the set of ids of organizer items which have been removed to the database
Returns the value of the data changed flag
See also setDataChanged().
Emits the appropriate signals from the given engine given the state of the change set
Inserts the given organizer item id addedOrganizerItemId into the set of ids of organizer items which have been added to the database.
Inserts each of the given organizer item ids addedOrganizerItemIds into the set of ids of organizer items which have been added to the database.
Inserts the given organizer item id changedOrganizerItemId into the set of ids of organizer items which have been changed to the database.
Inserts each of the given organizer item ids changedOrganizerItemIds into the set of ids of organizer items which have been changed to the database.
Inserts the given organizer item id removedOrganizerItemId into the set of ids of organizer items which have been removed to the database.
Inserts each of the given organizer item ids removedOrganizerItemIds into the set of ids of organizer items which have been removed to the database.
Returns the set of ids of organizer items which have been removed from the database.
Sets the data changed flag to dataChanged. If this is set to true prior to calling emitSignals(), only the QOrganizerManagerEngine::dataChanged() signal will be emitted; otherwise, the appropriate finer-grained signals will be emitted.
