- * Description: The RubyEventQueue class implements an event queue which
- * can be trigger events, allowing our simulation to be event driven.
- *
- * Currently, the only event we support is a Consumer being signaled
- * by calling the consumer's wakeup() routine.  Adding the event to
- * the queue does not require a virtual function call, though calling
- * wakeup() is a virtual function call.
- *
- * The method triggerEvents() is called with a global time.  All
- * events which are before or at this time are triggered in timestamp
- * order.  No ordering is enforced for events scheduled to occur at
- * the same time.  Events scheduled to wakeup the same consumer at the
- * same time are combined into a single event.
- *
- * The method scheduleConsumerWakeup() is called with a global time
- * and a consumer pointer.  The event queue will call the wakeup()
- * method of the consumer at the appropriate time.
- *
- * This implementation of RubyEventQueue uses a dynamically sized array
- * managed as a heap.  The algorithms used has O(lg n) for insert and
- * O(lg n) for extract minimum element. (Based on chapter 7 of Cormen,
- * Leiserson, and Rivest.)  The array is dynamically sized and is
- * automatically doubled in size when necessary.
