-/**
- * Implementation of {@link ItemLabelProvider} that provides updating
- * label information for a Model object.
- * 
- * The typical subclass will override the following methods:
- * #buildTextModel()
- *     return a {@link PropertyValueModel} that represents the text for the represented
- *     model object.
- * #buildImageModel()
- * 	   return a {@link PropertyValueModel} that represents the image for the represented
- * 	   model object
- * 
- * Other methods may be overridden, but take care to preserve the logic provided 
- * by this class.
