Constructor & Destructor Documentation

◆ TimeSliceThread()

TimeSliceThread::TimeSliceThread ( const String & threadName)
explicit

Creates a TimeSliceThread.

When first created, the thread is not running. Use the startThread() method to start it.

◆ ~TimeSliceThread()

TimeSliceThread::~TimeSliceThread ( )
override

Destructor.

Deleting a Thread object that is running will only give the thread a brief opportunity to stop itself cleanly, so it's recommended that you should always call stopThread() with a decent timeout before deleting, to avoid the thread being forcibly killed (which is a Bad Thing).

Member Function Documentation

◆ addTimeSliceClient()

void TimeSliceThread::addTimeSliceClient ( TimeSliceClient * clientToAdd,
int millisecondsBeforeStarting = 0 )

Adds a client to the list.

The client's callbacks will start after the number of milliseconds specified by millisecondsBeforeStarting (and this may happen before this method has returned).

◆ moveToFrontOfQueue()

void TimeSliceThread::moveToFrontOfQueue ( TimeSliceClient * clientToMove)

If the given client is waiting in the queue, it will be moved to the front and given a time-slice as soon as possible.

If the specified client has not been added, nothing will happen.

◆ removeTimeSliceClient()

void TimeSliceThread::removeTimeSliceClient ( TimeSliceClient * clientToRemove)

Removes a client from the list.

This method will make sure that all callbacks to the client have completely finished before the method returns.

◆ removeAllClients()

void TimeSliceThread::removeAllClients ( )

Removes all the active and pending clients from the list.

This method will make sure that all callbacks to clients have finished before the method returns.

◆ getNumClients()

int TimeSliceThread::getNumClients ( ) const

Returns the number of registered clients.

◆ getClient()

TimeSliceClient * TimeSliceThread::getClient ( int index) const

Returns one of the registered clients.

◆ contains()

bool TimeSliceThread::contains ( const TimeSliceClient * ) const

Returns true if the client is currently registered.
