void Wt::WIOService::initializeThread ( )

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.

void Wt::WIOService::post ( const boost::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.

void Wt::WIOService::schedule ( int  milliSeconds,
const boost::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.

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).

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.

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.
