Re: T5: Example usage of visit(SelectModelVisitor obj) for SelectModel interface?

[Daniel Jue]

I copied this code from AbstractSelectModel into my
GenericSelectionModel, and now it works again.  Later on I might see
if my GenericSelectionModel can just extend the Abstract one.

        public final void visit(SelectModelVisitor visitor) {
                List<OptionGroupModel> groups = getOptionGroups();

                if (groups != null) {
                        for (OptionGroupModel groupModel : groups) {
                                visitor.beginOptionGroup(groupModel);

                                visitOptions(groupModel.getOptions(), visitor);

                                visitor.endOptionGroup(groupModel);
                        }
                }

                visitOptions(getOptions(), visitor);
        }

        private void visitOptions(List<OptionModel> options,
                        SelectModelVisitor vistor) {
                if (options != null) {
                        for (OptionModel optionModel : options)
                                vistor.option(optionModel);
                }
        }

Hello all,

I have a

public class GenericSelectionModel<T> implements SelectModel {
...}

That I need to add this method to:

public void visit(SelectModelVisitor arg0) {...}

I think Howard added this in response to some enhancements to the T5
Palette component.  At the moment I can't quite wrap my head around
how to use it.  Any tips out there?

Thanks

Daniel
