The QContactChangeSet class provides a simple API to simplify the emission of state-change signals from QContactManagerEngine implementations.
This class can be utilised by backend implementations to ensure correct emission of the QContactManagerEngine::dataChanged(), QContactManagerEngine::contactsAdded(), QContactManagerEngine::contactsChanged() and QContactManagerEngine::contactsRemoved().
See also QContactManagerEngine.
Constructs a new change set
Constructs a copy of the other change set
Frees the memory used by this change set
Returns a reference to the set of ids of contacts which have been added to the database.
Returns a reference to the set of ids of contacts which have been affected by the addition of relationships to the database.
Returns a reference to the set of ids of contacts which have been changed in the database.
Clears all flags and sets of ids in this change set
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
Returns a reference to the pair of ids which represents the old and new self contact ids. The first id in the pair is the old self contact id, while the second id in the pair is the new self contact id. If the new id is different to the old id at the point in time when emitSignals() is called, the QContactManagerEngine::selfContactIdChanged() signal will be emitted.
Returns a reference to the set of ids of contacts which have been removed from the database.
Returns a reference to the set of ids of contacts which have been affected by the removal of relationships from the database.
Sets the data changed flag to dataChanged. If this is set to true prior to calling emitSignals(), only the QContactManagerEngine::dataChanged() signal will be emitted; otherwise, the appropriate finer-grained signals will be emitted.
See also dataChanged().
