How to use RequestFactory: .with(propertyRefs) for composition of objects

I am newbie to GWT and I need your professional advice.

My question is how to use RequestFactory: .with(propertyRefs) for kind of “tree” structures when these propertyRefs itself contain list of items I would like to retrieve.

Some details:

On the server-side I have hierarchy of four domain objects A,B,C,D:

  • A object contains (or I'd better say keep reference to) List
  • B contains List
  • C contains List .

All mentioned domain objects have its corresponding proxy interfaces AProxy, BProxy, CProxy, DProxy to use on the client side.

On the client side I would like to get all that hierarchy of objects by once requesting AProxy object so I would profit from the easiness of data access using “get” methods and wouldn’t be obliged to make looping server requests for every sub-object, sub-sub-objects etc.

Due to specification! I should use smth. like .with(“property ref”) to get one level of hierarchy but what about retrieving following levels of compositions (in my case List for every object B and List for every object C).

Thanks in advance.

Solution

  • We can use form .with("a.b","a.b.c") for hierarchical composition.
