Looks like a perfect fitting for RxJava, not sure why it add complexity.
Promises has no concept of subscription, so requests cannot be canceled,
also you will going to need to create a lot of SAM to support generics and
lambdas, this is already implemented in RxJava which is pretty mature
project used in servers and androids! and now in GWT ;)
This is what can be done in RxJava and you will need lot of code to get
there with promises ;)
RxGwt.click(buttonToLoadSomething)
// this will cancel the previous request… --v …if next click occurs
before previous has done
.switchOnNext(event -> autoRestService.loadZeroOneOrLotOfItems()
.doOnSubscribe(() -> table.cleanAndShowLoading() /* do this on each new
server request */)
.onErrorResumeNext(err -> { table.stopLoadingAndShowWhy(err); return
empty(); }))
.filter(item -> item.name.startWith("iDontLikeThisOne"))
.subscribe(item -> table.addRow(item));
I'll encourage to try it out, AutoREST will just guide you to a more
uniform API, instead of the RequestBuilder ModelVistor
(https://github.com/intendia-oss/autorest-gwt/blob/master/gwt/src/main/java/com/intendia/gwt/autorest/client/RequestResourceBuilder.java)
create your own using native XMLHTTPRequest. If you don't prefer Observable
is because you haven't used them ;), hehe or not! I' just trying to promote
rxjava-gwt.
