Detailed Description

Class for doing some arbitrary parcel of work in its own thread.

The task is exposed as a function object, so could be a lambda or a hand-written closure. CWorker can not be subclassed, instead it can be extended with rich callable task objects.

Definition at line 211 of file worker.h.

Member Function Documentation

◆ fromTask()

template<typename F >

static CWorker* swift::misc::CWorker::fromTask	(	QObject *	owner,
		const QString &	name,
		F &&	task
	)

inlinestatic

Returns a new worker object which lives in a new thread.

Note: The worker calls its own deleteLater method when finished. Typically assign it to a QPointer if you want to store it.

Parameters

owner	Will be the parent of the new thread (the worker has no parent).
name	A name for the task, which will be used to create a name for the thread.
task	A function object which will be run by the worker in its thread.

Definition at line 225 of file worker.h.

◆ result()

template<typename R >

R swift::misc::CWorker::result ( )

inline

Returns the result of the task, waiting for it to finish if necessary.

Template Parameters

R	The return type of the task.

Remarks: This function is thread safe.

Definition at line 270 of file worker.h.

◆ thenWithResult() [1/2]

template<typename R , typename F >

void swift::misc::CWorker::thenWithResult ( F functor )

inline

Connects to a functor to which will be passed the result when the task is finished.

Template Parameters

R	The return type of the task.

Remarks: This function is thread safe. The functor may not call any method that observes the worker's finished flag.

Definition at line 243 of file worker.h.

◆ thenWithResult() [2/2]

template<typename R , typename T , typename F >

void swift::misc::CWorker::thenWithResult	(	T *	context,
		F	functor
	)

inline

Connects to a functor or method to which will be passed the result when the task is finished.

Template Parameters

R	The return type of the task.

Remarks: This function is thread safe. The functor may not call any method that observes the worker's finished flag.
