** * Note that I've flattened the object, such that * the site and application ID are in this object, rather than in an object/class * of their own. This is a questionable move.
* * It inherits from PduElement, the abstract class that all non-PDUs inherit * from. As usual, it knows how to serialize and deserialize itself, clone * itself, etc.
* * The event ID is used to keep events straight. It is employed in the fire and * detonation PDUs, for example.
* * This is extremely similar to the EventID class. It includes a hash function for * the object, in case we want to use this as a key in a hash table.
