Detailed Description

Records and replays change notification.

This class is responsible for recording change notifications while an agent is not online and replaying the notifications when the agent is online again. Therefore the agent doesn't have to care about online/offline mode in its synchronization algorithm.

Unlike Akonadi::Monitor this class only emits one change signal at a time. To receive the next one you need to explicitly call replayNext(). If a signal is emitted that has no receivers, it's automatically skipped, which means you only need to connect to signals you are actually interested in.

Constructor & Destructor Documentation

◆ ChangeRecorder()

ChangeRecorder::ChangeRecorder ( QObject * parent = nullptr)

Creates a new change recorder.

Definition at line 14 of file changerecorder.cpp.

◆ ~ChangeRecorder()

ChangeRecorder::~ChangeRecorder ( )

Destroys the change recorder.

All not yet processed changes are written back to the config file.

Definition at line 24 of file changerecorder.cpp.

Member Function Documentation

◆ changeProcessed()

void ChangeRecorder::changeProcessed ( )

Removes the previously emitted change from the records.

Definition at line 80 of file changerecorder.cpp.

◆ changesAdded

void Akonadi::ChangeRecorder::changesAdded ( )

Emitted when new changes are recorded.

◆ dumpNotificationListToString()

QString Akonadi::ChangeRecorder::dumpNotificationListToString ( ) const

Debugging: dump current list of notifications, as saved on disk.

Definition at line 111 of file changerecorder.cpp.

◆ isEmpty()

bool ChangeRecorder::isEmpty ( ) const

Returns whether there are recorded changes.

Definition at line 74 of file changerecorder.cpp.

◆ nothingToReplay

void Akonadi::ChangeRecorder::nothingToReplay ( )

Emitted when replayNext() was called, but there was no valid change to replay.

This can happen when all pending changes have been filtered out, for example. You only need to connect to this signal if you rely on one signal being emitted as a result of calling replayNext().

◆ replayNext

void ChangeRecorder::replayNext ( )

Replay the next change notification and erase the previous one from the record.

Definition at line 43 of file changerecorder.cpp.

◆ setChangeRecordingEnabled()

void ChangeRecorder::setChangeRecordingEnabled ( bool enable)

Enables change recording.

If change recording is disabled, this class behaves exactly like Akonadi::Monitor. Change recording is enabled by default.

enablefalse to disable change recording. true by default

Definition at line 96 of file changerecorder.cpp.

◆ setConfig()

void ChangeRecorder::setConfig ( QSettings * settings)

Sets the QSettings object used for persistent recorded changes.

Definition at line 28 of file changerecorder.cpp.
