BasicAwaiter< void > Class Reference

#include <Pt/Coroutine.h>

Specializes BasicAwaiter for awaitables without a result. More...

Inherits Awaiter.

Inherited by AsyncWait.

Public Member Functions
void	await_resume ()
	Resumes the coroutine after the operation completed.
bool	await_ready () const
	Returns false so co_await always suspends.
template<typename P >
bool	await_suspend (std::coroutine_handle< P > h)
	Starts the operation and suspends the coroutine.
void	cancel () override
	Cancels the in-flight operation.

Protected Member Functions
virtual void	onReady ()=0
	Finalizes the operation when the awaitable resumes. More...
void	setReady ()
	Resumes the waiting coroutine. More...
virtual void	onBegin ()=0
	Starts the asynchronous operation. More...
virtual void	onCancel ()=0
	Aborts the in-flight operation. More...

Detailed Description

Use this when the operation completes without producing a value. Implement BasicAwaiter::onReady() to finalize or clean up.

Member Function Documentation

onReady()

virtual void onReady ( )

protectedpure virtual

Called exactly once when the coroutine is resumed.

setReady()

void setReady ( )

protectedinherited

Call this when the asynchronous operation has completed. Typically connect a completion signal to this method.

onBegin()

virtual void onBegin ( )

protectedpure virtualinherited

Subscribe to completion and begin the work. The coroutine remains suspended until Awaiter::setReady() is called.

Implemented in AsyncYield.

onCancel()

virtual void onCancel ( )

protectedpure virtualinherited

Called from Awaiter::cancel() when the waiting task or generator is cancelled.

Implemented in AsyncYield.
