Detailed Description

Class ProcessAllPagesBackgroundTask.

A simple background task that takes a ProcessAllPagesHandler and a box, and runs the processing in the background using its run() method. If no ProcessAllPagesHandler is given or set to NULL, a processAllPages(-1) is started on the Module.
