DeincrementGroup ( IWorkGroup group ) : void	De-increments the task counter for a specific group.
Dispose ( bool disposing ) : void	Releases unmanaged and - optionally - managed resources.

Method Details

AddTask() public méthode

Adds a new task to the scheduler.

public AddTask ( Task task ) : void
task	Task	The task.
Résultat	void

AddWorkGroup() public méthode

Adds a new work group.

public AddWorkGroup ( string name, int concurrencyLevel ) : IWorkGroup
name	string	The name.
concurrencyLevel	int	The concurrency level.
Résultat	IWorkGroup

AddWorkGroup() public méthode

Adds a new work group.

Start must be called on the scheduler before adding work groups
