Detailed Description

template<typename CtxType>
class util::async::RepeatingOperation< CtxType >

The future side of async operations that automatically repeat until aborted.

Note

The current implementation requires the user provided function to return void and to take no arguments. There is also no mechanism to request the repeating task to stop from inside of the user provided block of code.

Template Parameters

CtxType

The type of the execution context

Constructor & Destructor Documentation

RepeatingOperation()

template<typename CtxType >

util::async::RepeatingOperation< CtxType >::RepeatingOperation ( auto & executor, std::chrono::steady_clock::duration interval, std::invocable auto && fn )

inline

Construct a new Repeating Operation object.

Note

The first invocation of the user-provided function happens with no delay

Parameters

executor	The executor to operate on
interval	Time to wait before repeating the user-provided block of code
fn	The function to execute repeatedly

Member Function Documentation

abort()

template<typename CtxType >

void util::async::RepeatingOperation< CtxType >::abort ( )

inlinenoexcept

Aborts the operation and the repeating timer.

Note

This call blocks until the underlying timer is cancelled

Warning

Calling this from inside of the repeating operation yields a deadlock
