C# Class Sharplike.Core.Scheduling.PrioritizedThreadPoolScheduler

The class for a prioritized scheduler. Internally the class uses SortedList for relatively efficient insertion and deletion of tasks, and is recommended only for multi-threaded schedulers.

Public Methods

Method	Description
AddTask ( IScheduledTask task ) : void	Adds a task to the priority queue. As no priority value has been given, the scheduler will use the delegate in TaskPriorityAlgorithm to determine a priority for the task. Failure to set TaskPriorityAlgorithm ahead of time will throw an exception.
AddTask ( Int32 priority, IScheduledTask task ) : void	Adds a task to the scheduler with the specified priority.
ClearTasks ( ) : void	Clears the scheduler of all tasks.
PrioritizedThreadPoolScheduler ( ) : System	Constructor.
Process ( ) : void	Dispatches a "go" message to all subscribed processes.
RemoveTask ( IScheduledTask task ) : System.Boolean	Remove a task from the scheduler. This is a fail-safe function; it will not throw an exception if the task is not in the scheduler. Note that this function only removes the first occasion of a task; if you have accidentally registered the same task multiple times, it only removes one.
ReorderTasks ( ) : void	Feeds all currently enqueued tasks through the designated TaskPriorityAlgorithm to reorder them. This is a computationally slow function and should be called with caution.

Method Details

AddTask() public method

Adds a task to the priority queue. As no priority value has been given, the scheduler will use the delegate in TaskPriorityAlgorithm to determine a priority for the task. Failure to set TaskPriorityAlgorithm ahead of time will throw an exception.

public AddTask ( IScheduledTask task ) : void
task	IScheduledTask	The task to add to the scheduler.
return	void

AddTask() public method

Adds a task to the scheduler with the specified priority.

public AddTask ( Int32 priority, IScheduledTask task ) : void
priority	System.Int32	The current task's priority for scheduling.
task	IScheduledTask	The task to be queued.
return	void

ClearTasks() public method

Clears the scheduler of all tasks.

public ClearTasks ( ) : void
return	void

PrioritizedThreadPoolScheduler() public method

Constructor.

public PrioritizedThreadPoolScheduler ( ) : System
return	System

Process() public method

Dispatches a "go" message to all subscribed processes.

public Process ( ) : void
return	void

RemoveTask() public method

Remove a task from the scheduler. This is a fail-safe function; it will not throw an exception if the task is not in the scheduler. Note that this function only removes the first occasion of a task; if you have accidentally registered the same task multiple times, it only removes one.

public RemoveTask ( IScheduledTask task ) : System.Boolean
task	IScheduledTask	The task to remove.
return	System.Boolean

ReorderTasks() public method

Feeds all currently enqueued tasks through the designated TaskPriorityAlgorithm to reorder them. This is a computationally slow function and should be called with caution.

public ReorderTasks ( ) : void
return	void
