value. There's no way to actually implement this check in
GWT client-side code. In order to prevent users from having to check for
the root context in a visitor to avoid a special case, we'll just return
the object. If the value really isn't assignable to T, a call to
setInModel(Object) will fail in the generated code, which has an
explicit cast.checkAssignment in interface EditorContext<T>checkAssignment in class AbstractEditorContext<T>value - any value, including nullvalue cast to the T typepublic Class<T> getEditedType()
