dominikriemer opened a new issue, #800:
URL: https://github.com/apache/streampipes/issues/800

   I just wondering on the example with the 1 class processor here [1] [2].
   
   In the description is mentioned that
   
   Next, we are interested in the fields of the input event stream that contains the latitude and longitude value we would like to compute against the geofence center location as follows:
   
   ```
   
   String latitudeFieldName = extractor.mappingPropertyValue("latitude-field");
   String longitudeFieldName
   = extractor.mappingPropertyValue("longitude-field");
   
   ```
   
   
   
   1) Shouldn't it be:
   ```
   
   String latitudeFieldName = parameters.extractor().mappingPropertyValue("latitude-field");
   String longitudeFieldName
   = parameters.extractor().mappingPropertyValue("longitude-field");
   
   ```
   
   
   
   2) But this code snippet is  is missing in "Your controller class should look as follows" example.
   
   3) The latitudeFieldName is used in the onEvent Method as
   ```
   
   float latitude = event.getFieldBySelector(latitudeFieldName).getAsPrimitive().getAsFloat();
   float
   longitude = event.getFieldBySelector(longitudeFieldName).getAsPrimitive().getAsFloat();
   
   ```
   
   But the variables can not be resolved. 
   
   I but the example code into a file but better overview
    [^GeofencingProcessor.java]
