Member Function Documentation

virtual RunningState Mezzanine::Threading::iAsynchronousWorkUnit::IsWorkDone ( )
pure virtual

This will atomically allow any thread to check if this WorkUnit has completed its work.

Returns
This returns a RunningState indicating the current status of the asynchronous work.

Implemented in Mezzanine::Threading::AsynchronousFileLoadWorkUnit.
