Include dependency graph for Async/Utilities.h:

This graph shows which files directly or indirectly include this file:

Classes
class	LLU::Async::FunctionWrapper
	Wraps an arbitrary callable object (possibly binding its arguments) to be evaluated later. The callable object, when called on provided arguments, must return void. More...

class	LLU::Async::ThreadJoiner
	A guard for a vector of threads to make sure they are joined before their destruction. The developer must ensure that the lifetime a ThreadJoiner does not exceed the lifetime of the vector it guards. More...

class	LLU::Async::Pausable
	Utility class for pausable task queues. More...

Namespaces
	LLU
	Main namespace of LibraryLink Utilities.

Functions
template<typename FunctionType , typename... Args>
std::packaged_task< std::invoke_result_t< FunctionType, Args... >)>	LLU::Async::getPackagedTask (FunctionType &&f, Args &&... args)
	Create a std::packaged_task from a callable object and arguments to it. More...

Function Documentation

template<typename FunctionType , typename... Args>

std::packaged_task<std::invoke_result_t<FunctionType, Args...>)> LLU::Async::getPackagedTask	(	FunctionType &&	f,
		Args &&...	args
	)

Create a std::packaged_task from a callable object and arguments to it.

Template Parameters

FunctionType	- arbitrary type of a callable object
Args	- paramater pack with function argument types

Parameters

f	- callable object
args	- arguments for a call to `f`

Returns: a call to f with arguments args wrapped in a std::packaged_task
