Update a composed entity in greenDao

Let say i have a business domain in which there are two entities, Survey and Question, in OOP terms, the Survey has QuestionsList, the greenDao generation getQuestions method which returns a list of questions resolving 1:M relation from Survey to Question, but there is no method like setQuestions( questionList) which will take a list of question to update. How can i update the questionList for the Survey entity ?

you can use:

getQuestions().add(Question);

but for setting Question parent you should set ParentId for your Question and then add it to QuestionList of Survey. ParentId is the foreign-key of Question which links a question to a survey. Remember that you must store Question after these changes.
