public interface EventInfo
A general interface that represents data to be passed to EventListener objects that are registered to be notified when some events happen for a given simulation entity such as a Datacenter, Host, Vm, Cloudlet and so on.

There is not implementing class for such interfaces because instances of them are just Data Type Objects (DTO) that just store data and do not have business rules. Each interface that extends this one has a getInstance() method to create an object from that interface. Such method uses the JDK8 static methods for interfaces to provide such a feature e reduce the number of classes, providing a simpler design.
