79e08fd0 | 34 | * The generic Statistics View displays statistics for any kind of traces. |
20ff3b75 | 35 | * |
09667aa4 MD |
36 | * It is implemented according to the MVC pattern. - The model is a |
37 | * TmfStatisticsTreeNode built by the State Manager. - The view is built with a | |
38 | * TreeViewer. - The controller that keeps model and view synchronized is an | |
39 | * observer of the model. | |
