23.5.1 Priority Queue - Example

• Discrete event-driven simulation - classic application
• Structured around events (actions) that occur at some fixed time
• Often an action will spawn new events
• The following 2 files are the basis for an event-driven simulation
• Each event will be represented by an instance of Event
• The Event records the time, the key for comparison
• The lower time has higher priority
• A pure virtual method represents the action of an event
