```
    Return the SurfacesInfo of this node.

  - markTileAsInstalled
```
 final Unit markTileAsInstalled(String tileName)
```
    Marks a tile as installed. Call this in TileService#onTileAddEvent. Supplying a name is mandatory to disambiguate from the installation or removal of other tiles your app may have.
    
    Parameters:
    
    tileName - The name of the tile.
  - markActivityLaunchedOnce
```
 final Unit markActivityLaunchedOnce()
```
    Marks that the main activity has been launched at least once.
  - markSetupComplete
```
 final Unit markSetupComplete()
```
    Marks that the necessary setup steps have been completed in the app such that it is ready for use. Typically this should be called when any pairing/login has been completed.
  - markSetupNoLongerComplete
```
 final Unit markSetupNoLongerComplete()
```
    Marks that the app is no longer considered in a fully setup state. For example, the user has logged out. This will roll the state back to the app having been used once - if the setup had previously been completed, but will have no effect if this is not the case.
  - markTileAsRemoved
```
 final Unit markTileAsRemoved(String tileName)
```
    Marks a tile as removed. Call this in TileService#onTileRemoveEvent. Supplying a name is mandatory to disambiguate from the installation or removal of other tiles your app may have.
    
    Parameters:
    
    tileName - The name of the tile.
  - markComplicationAsActivated
```
 final Unit markComplicationAsActivated(String complicationName, Integer complicationInstanceId, ComplicationType complicationType)
```
    Marks a complication as activated. Call this in ComplicationDataSourceService.onComplicationActivated.
    
    Parameters:
    
    complicationName - The name of the complication, to disambiguate from others.
    
    complicationInstanceId - Passed from ComplicationDataSourceService.onComplicationActivated
    
    complicationType - Passed from ComplicationDataSourceService.onComplicationActivated
  - markComplicationAsDeactivated
```
 final Unit markComplicationAsDeactivated(String complicationName, Integer complicationInstanceId, ComplicationType complicationType)
```
    Marks a complication as deactivated. Call this in ComplicationDataSourceService.onComplicationDeactivated.
    
    Parameters:
    
    complicationName - The name of the complication, to disambiguate from others.
    
    complicationInstanceId - Passed from ComplicationDataSourceService.onComplicationDeactivated
    
    complicationType - Passed from ComplicationDataSourceService.onComplicationDeactivated
