Inheritance diagram for Digikam::ParallelWorkers:Public Member Functions | |
| ParallelWorkers ()=default | |
| ParallelWorkers is a helper class to distribute work over several identical workers objects. | |
| virtual bool | connect (const char *signal, const QObject *receiver, const char *method, Qt::ConnectionType type=Qt::AutoConnection) const |
| Connects signals outbound from all workers to a given receiver. | |
| virtual void | deactivate (WorkerObject::DeactivatingMode mode=WorkerObject::FlushSignals) |
| bool | optimalWorkerCountReached () const |
| virtual void | schedule () |
| The corresponding methods of all added worker objects will be called. | |
| void | setPriority (QThread::Priority priority) |
| virtual void | wait () |
Static Public Member Functions | |
| static int | optimalWorkerCount () |
| Regarding the number of logical CPUs on the current machine, returns the optimal count of concurrent workers. | |
Protected Types | |

Protected Member Functions | |
| void | add (WorkerObject *const worker) |
| virtual QObject * | asQObject ()=0 |
| virtual const QMetaObject * | mocMetaObject () const =0 |
| The moc-generated metaObject of the target object. | |
| const QMetaObject * | replacementMetaObject () const |
| int | replacementQtMetacall (QMetaObject::Call _c, int _id, void **_a) |
| Replaces slot call distribution of the target QObject. | |

| virtual StaticMetacallFunction | staticMetacallPointer ()=0 |
| virtual int | WorkerObjectQtMetacall (QMetaObject::Call _c, int _id, void **_a)=0 |
| The qt_metacall of WorkerObject, one level above the target QObject. | |
