virtual void execute

(

int

index

)

[pure virtual]

This method defines the task to be performed.

When the Task is passed to a ParallelExecutor's execute() method, this method will be called in parallel the specified number of times.

virtual void finish

(

)

[inline, virtual]

This method is invoked once by each worker thread after all invocations of the task on that thread are complete.

This can be used to clean up thread-local storage, or to record per-thread results. All calls to this method are synchronized, so it can safely write to global variables without danger of interference between worker threads.

virtual void initialize

(

)

[inline, virtual]

This method is invoked once by each worker thread before the task is executed.

This can be used to initialize thread-local storage.
