public void onStartBuild(AndroidMetawidget metawidget)
```
    Description copied from interface: AdvancedWidgetProcessor
    
    Event called at the start of the widget building process, before the WidgetBuilder is called. WidgetProcessors may wish to act on this event to initialize themselves ready for processing. This event is only called once per inspection, not once per widget built.
    
    Specified by:
    
    onStartBuild in interface AdvancedWidgetProcessor<android.view.View,AndroidMetawidget>
    
    Parameters:
    metawidget - the parent Metawidget. Never null
  - processWidget
```
public android.view.View processWidget(android.view.View view,
                              String elementName,
                              Map<String,String> attributes,
                              AndroidMetawidget metawidget)
```
    Description copied from interface: WidgetProcessor
    
    Process the given widget. Called after a widget has been built by the WidgetBuilder, and before it is added to the Layout.
    
    Specified by:
    
    processWidget in interface WidgetProcessor<android.view.View,AndroidMetawidget>
    
    Parameters:
    view - the widget to process. Never null
    elementName - XML node name of the business field. Typically 'entity', 'property' or 'action'. Never null
    attributes - attributes of the widget to process. Never null. This Map is modifiable - changes will be passed to subsequent WidgetProcessors and Layouts
    metawidget - the parent Metawidget. Never null
    
    Returns:
    generally the original widget (as passed in to the first argument). Can be a different widget if the WidgetProcessor wishes to substitute the original widget for another. Can be null if the WidgetProcessor wishes to cancel all further processing of this widget (including laying out)
  - onEndBuild
```
public void onEndBuild(AndroidMetawidget metawidget)
```
    Description copied from interface: AdvancedWidgetProcessor
    
    Event called at the end of widget building, after all widgets have been built and added to the Layout. WidgetProcessors may wish to act on this event to clean themselves up after processing. This event is only called once per inspection, not once per widget built.
    
    Specified by:
    
    onEndBuild in interface AdvancedWidgetProcessor<android.view.View,AndroidMetawidget>
    
    Parameters:
    metawidget - the parent Metawidget. Never null
