Public Methods

Method	Description
DisposeOfState ( ) : void
Execute ( ) : void	Execute the work item and the post execute

Private Methods

Method	Description
Cancel ( bool abortExecution ) : bool	Cancel the work item if it didn't start running yet.
ExecuteWorkItem ( ) : void	Execute the work item
FireWorkItemCompleted ( ) : void
FireWorkItemStarted ( ) : void
GetResult ( int millisecondsTimeout, bool exitContext, WaitHandle cancelWaitHandle ) : object	Get the result of the work item. If the work item didn't run yet then the caller waits for the result, timeout, or cancel. In case of error the method throws and exception
GetResult ( int millisecondsTimeout, bool exitContext, WaitHandle cancelWaitHandle, Exception &e ) : object	Get the result of the work item. If the work item didn't run yet then the caller waits for the result, timeout, or cancel. In case of error the e argument is filled with the exception
GetWaitHandle ( ) : WaitHandle	A wait handle to wait for completion, cancel, or timeout
GetWaitHandles ( IWaitableResult waitableResults, WaitHandle waitHandles ) : void	Fill an array of wait handles with the work items wait handles.
GetWorkItemResult ( ) : IWorkItemResult	Returns the work item result
GetWorkItemState ( ) : WorkItemState
Initialize ( ) : void
IsValidStatesTransition ( WorkItemState currentState, WorkItemState nextState ) : bool
PostExecute ( ) : void	Runs the post execute callback
ReleaseWaitHandle ( ) : void
ReleaseWaitHandles ( IWaitableResult waitableResults ) : void	Release the work items' wait handles
SetResult ( object result, Exception exception ) : void	Set the result of the work item to return
SetWorkItemState ( WorkItemState workItemState ) : void	Sets the work item's state
SignalComplete ( bool canceled ) : void	Signals that work item has been completed or canceled
WaitAll ( IWaitableResult waitableResults, int millisecondsTimeout, bool exitContext, WaitHandle cancelWaitHandle ) : bool	Wait for all work items to complete
WaitAny ( IWaitableResult waitableResults, int millisecondsTimeout, bool exitContext, WaitHandle cancelWaitHandle ) : int	Waits for any of the work items in the specified array to complete, cancel, or timeout
WasQueuedBy ( IWorkItemsGroup workItemsGroup ) : bool
WorkItemIsQueued ( ) : void
