Controller

java.lang.Object
- edu.kit.ipd.sdq.eventsim.rvisualization.Controller

```
public class Controller
extends Object
```
Glues together the FilterView and DiagramView on the one side, and the FilterModel and FilterSelectionModel on the other side.
Responsibilities of this controller include:
- observe FilterSelectionModel for selection events (mainly triggered by the user), and react to the selection by modifying the FilterModel. Data binding established by the FilterView ensures that the view reflects the model at any time. Explicit view updates triggered by this controller are not required, usually. Likewise, it is not necessary to query the view's (selection) state because the (selection) model provides that information.
- populate the FilterModel from measurements stored in R with the help of the RController.
- trigger diagram plots in R with the help of the RController.

Constructor Detail
- Controller
```
public Controller(FilterView view,
                  FilterSelectionModel selectionModel,
                  FilterModel model)
```
  Create an application controller. The application controller creates a RController to manage the R connection and a MeasurementView to open the main SWT dialog.

Method Detail

viewInitialized
```
public final void viewInitialized()
```

reload
```
public final void reload()
```

loadRDS
```
public void loadRDS(String path)
```
Parameters:

path - the path to the RDS file to be loaded. All occurrences of "\" will be converted to "/" for compliance with R.

resetSimulationTimeBounds

public final void resetSimulationTimeBounds()

clearSelectionTriggerTypes

public void clearSelectionTriggerTypes()

clearSelectionTriggerInstances

public void clearSelectionTriggerInstances()

plotDiagram
```
public final void plotDiagram()
```
Plots the diagram according to the current FilterSelectionModel. The generated diagram will be opened in a new DiagramView.

metadataSelectionChanged

public void metadataSelectionChanged(TranslatableEntity metadataType,
                                     Metadata metadataLevel)

metadataSelectionCleared

public void metadataSelectionCleared()
