public class MvModelEvent

extends java.lang.Object

Model event message.

Details: An MvModelEvents conveys information about an event that occurred in a model, an event in which the model's views may be interested. Instances of this class are typically sent from MvModels to MvViews through the notifyViews and updateView methods. MvModels are not required to use this object for messaging, but it is provided as a convenience.

An MvModelEvent is a triplet: (model, type, params). model identifies the model sending the message, type identifies the type of message, and params is a vector of data whose size, format, and interpretation depend on type.
