Detailed Description

Abstract base class for sets of integer semaphores.

Each instance represents one set of integer semaphores.

Specific platforms dereive their implementation classes from this class.

The instances are created by LOW_semaphoreSetFactory, following the factory design pattern.

Note: There is no prescribed constructor. A class deriving from this class should give the opportunity to specify the number of semaphores in the set and their initial value.
