Details
ProtectedQueue implements a FIFO queue with the following functionality:
- Multiple threads could be simultaneously trying to enqueue and dequeue. Hence the queue needs to be protected with mutex.
- In case the queue is empty, dequeue() sleeps for a specified amount of time, or until a new element is inserted, whichever is earlier.
