Detailed Description

Interface of a barrier between threads.

Once created (via IThreadImplementation::createBarrier()), the barrier must be initialized via init() for n threads. Then, each thread must call the wait() method to wait until all other threads reach this same point. The barrier can be used multiple times. To destroy the barrier, you must call destroy(). This also frees the instance which should no longer be used.
