question: public static Map < String , Object > makeValidContext ( ModelService model , String mode , Map < String , ? extends Object > context ) throws GenericServiceException { Map < String , Object > newContext ; int modeInt = 0 ; if ( mode . equalsIgnoreCase ( "in" ) ) { modeInt = 1 ; } else if ( mode . equalsIgnoreCase ( "out" ) ) { modeInt = 2 ; } if ( model == null ) { throw new GenericServiceException ( "Model service is null! Should never happen." ) ; } else { switch ( modeInt ) { case 2 : newContext = model . makeValid ( context , ModelService . OUT_PARAM , true , null ) ; break ; case 1 : newContext = model . makeValid ( context , ModelService . IN_PARAM , true , null ) ; break ; default : throw new GenericServiceException ( "Invalid mode, should be either IN or OUT" ) ; } return newContext ; } }
target:  Uses an existing map of name value pairs and extracts the keys which are used in serviceName Note: This goes not guarantee the context will be 100% valid, there may be missing fields
