Public Methods

Method	Description
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
RoundRobinThreadAffinedTaskScheduler ( int numberOfThreads ) : System	Create a new RoundRobinThreadAffinedTaskScheduler with a provided number of background threads. Threads are pined to a logical core using a round robin algorithm.

Protected Methods

Method	Description
GetScheduledTasks ( ) : IEnumerable	Generates an enumerable of T:System.Threading.Tasks.Task instances currently queued to the scheduler waiting to be executed.
QueueTask ( Task task ) : void	Queues a T:System.Threading.Tasks.Task to the scheduler.
TryExecuteTaskInline ( Task task, bool taskWasPreviouslyQueued ) : bool	Determines whether the provided T:System.Threading.Tasks.Task can be executed synchronously in this call, and if it can, executes it.

Method Details

Dispose() public method

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public Dispose ( ) : void
return	void

GetScheduledTasks() protected method

Generates an enumerable of T:System.Threading.Tasks.Task instances currently queued to the scheduler waiting to be executed.

This scheduler is unable to generate a list of queued tasks at this time.

protected GetScheduledTasks ( ) : IEnumerable
return	IEnumerable

QueueTask() protected method

Queues a T:System.Threading.Tasks.Task to the scheduler.

The argument is null.

protected QueueTask ( Task task ) : void
task	Task	The to be queued.
return	void

RoundRobinThreadAffinedTaskScheduler() public method

Create a new RoundRobinThreadAffinedTaskScheduler with a provided number of background threads. Threads are pined to a logical core using a round robin algorithm.

public RoundRobinThreadAffinedTaskScheduler ( int numberOfThreads ) : System
numberOfThreads	int	Total number of threads in the pool.
return	System

TryExecuteTaskInline() protected method

Determines whether the provided T:System.Threading.Tasks.Task can be executed synchronously in this call, and if it can, executes it.

The argument is null. The was already executed.

protected TryExecuteTaskInline ( Task task, bool taskWasPreviouslyQueued ) : bool
task	Task	The to be executed.
taskWasPreviouslyQueued	bool	A Boolean denoting whether or not task has previously been queued. If this parameter is True, then the task may have been previously queued (scheduled); if False, then the task is known not to have been queued, and this call is being made in order to execute the task inline without queuing it.
return	bool
