Interface ViewDriver

public interface ViewDriver
Describes a view resolution driver for Small.

When a EntryPath method returns a View, it is passed to one of these components to render.

There can be many components with this role - the handleView(HttpServletRequest, HttpServletResponse, Object, String) method is called and if it returns false, the next ViewDriver is called, and if it returns true, handling stops.
