Member Function Documentation

initializeThread()

void Wt::WIOService::initializeThread ( )

virtual

Initializes a thread.

This function is called for every new thread created, and can be used to configure the thread, e.g. with respect to scheduling priorities.

post()

void Wt::WIOService::post

(

const std::function< void()> &

function

)

Posts a function into the thread-pool.

The function will be executed within a thread of the thread-pool.

This method returns immediately.

schedule()

void Wt::WIOService::schedule	(	std::chrono::steady_clock::duration	millis,
		const std::function< void()> &	function
	)

Schedules a function on the thread-pool.

The function will be executed after a time out, specified in milli-seconds, on the thread pool.

setThreadCount()

void Wt::WIOService::setThreadCount

(

int

number

)

Configures the number of threads.

This must be configured before the server is started using start().

The default thread count is 5 (or is configured by WServer from information in the configuration file).

start()

void Wt::WIOService::start

(

)

Starts the I/O service.

This will start the internal thread pool to process work for the I/O service, if not already started.

stop()

void Wt::WIOService::stop

(

)

Stops the I/O service.

This will stop the internal thread pool. The method will block until all work has been completed.
