Detailed Description

A thread that keeps a list of clients, and calls each one in turn, giving them all a chance to run some sort of short task.

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.
