Talk:Question object types
From LimeSurvey Manual
Question object specification text
1. I think specification is not the same as (our) implementation.
2. Specifications should consist of interfaces (and optionally abstract classes) only.
Current LS3 implementation
Note, this is the current state and some of these are mostly because it is a refactoring from LS2.
1. Uses an interface.
2. Defines what columns it needs via a fieldname => column type map.
3. Defines what EM expressions apply to it.
4. Defines a render functionality that renders the content.
5. Defines a list of classes that should be in the wrapping div.
