Detailed Description

The item_with_predicate.h file is a class which we implement and document here.

The class is used to add sets of items in a FIFO of a pool of workers, items which depend on each other. If a dependency is still defined, then the item is skipped (left in the FIFO) until the valid_workload() returns true, which happens once all the dependencies were worked on.

Note

We consider this base class as an example. Your own version of the valid_workload() function could use all sorts of predicates. For example, a workload may become valid only after a given date and time, when a file appears, etc.
