Extracting member information

Hello bassybassy,

PsiClass.getMethods()/getFileds()/getInnerClasses() is the API that you need.

This question is about the IntelliJ API best practices way of
extracting the members of the class which is in currently the editor.

Basically, just want to extract all the members of the current class
so they can be presented  in a dialog. Obviously super classes and
inner classes and interfaces are of interest also but this is probably
just a recursive procedure. Like  ExtractClass or ExtractInterface
refactorings do. Did find ExtractinterfaceDialog and
ExtractInterfaceHandler and all this to use as exemplars.   Nosing
around ran into   MemberInfo.extractClassMembers but it seems to not
be used that much in the IntelliJ source, which suggests there's some
other more efficient  way somewhere?

Regarding MemberInfo.extractClassMembers- it puts everything into an
typed List : List<MemberInfo>  and then the consumers of this list
end up having to instanceof the individual items to identify them as
being a field or method or whatnot. Is this just how it's done or is
there another way? It seems like there ought to be a more  natural API
like getFields() getMethods getInnerClasses etc etc. but maybe there's
more to it than  that.
