[15:18:59] <spriet2000> hi

[15:19:14] <AlexLehm> hi

[15:19:17] <spriet2000> what's a good approach for doing a number x of async methods, wait till all methods have returned something and do something else with the collected values?

[15:19:56] <spriet2000> its all local so evenbus isn't necessary

[15:21:13] <AlexLehm> you could use rx I think

[15:21:44] <spriet2000> but it should be possible with core object also right?

[15:22:22] <AlexLehm> you can probably use Future and combine them in some way

[15:22:58] <spriet2000> yea i am learning how to deal with futures and async results

[15:23:08] <AlexLehm> e.g. put them in a Concurrent Set and count the number of completed elements

[15:23:52] <AlexLehm> I have a close operation in the connection pool that counts down the number of open connections and removes them from the map

[15:24:16] <AlexLehm> you could do about the same thing by counting up to the size of the map

[15:24:42] <AlexLehm> or Set

[15:24:53] <spriet2000> now i have something like

[15:25:03] <spriet2000> which doesnt work

[15:25:23] <spriet2000> but i am figuring out how to handle future stuff

[15:25:53] <spriet2000> concurrent map is probarly better than a list

[15:26:25] <spriet2000> a future isnt executed async automaticly right?

[15:28:58] <AlexLehm> the future can be executed async but you cannot wait for the completion syncchronous

[15:29:05] <AlexLehm> (i think)

[15:29:18] <spriet2000> exactly that will block

[15:29:49] <AlexLehm> but Future has a handler, do you can process the result with that

[15:30:18] <spriet2000> yeps

[15:37:55] <spriet2000> if you want to process a couple of methods at the same time what is the correct way to start them? is invented for that kind of situations?

[17:21:44] <spriet2000> future is nice!

[17:48:44] <AlexLehm> tekacs,

[17:48:46] <AlexLehm> sorry

[17:49:25] <tekacs> autocomplete? :P

[17:49:52] <AlexLehm> yes, i meant to address temporalfox

[17:50:35] <AlexLehm> temporalfox, when i use codegen on a package it generates the files for the classes that are not included in the source but are references as project, not sure if that is correct

[17:51:17] <AlexLehm> spriet2000, haven't used Future much yet, but that should make joining a few results easy

[18:27:07] <temporalfox> AlexLehm I don't understand what you mean :-)

[18:27:23] <temporalfox> you mean dependencies ?

[18:27:30] <temporalfox> do you have an example ?

[18:27:54] <AlexLehm> we have refactored the mail project into two maven modules, vertx-mail-client and vertx-mail-service and service depends on client

[18:28:13] <AlexLehm> now the codegen generates the files for client in the service project once more

[18:30:20] <AlexLehm>

[18:30:38] <AlexLehm> i may be calling the process wrong though

[18:31:04] <AlexLehm> I would expect that only the mail_service.rb would be generated in this case

[18:36:35] <spriet2000> i have it working now :>

[18:36:46] <spriet2000> thanks

[18:41:10] <spriet2000> although i still have questions about runoncontext why and when to use and if its expensive in use[unknown:hellip] but thats for later

[19:00:06] <temporalfox> I will have a look AlexLehm

[19:00:34] <temporalfox> I don'treally get why we had to split in two modules though

[19:02:10] <AlexLehm> i assume to avoid getting the dependencies on the proxy when it is not used

[19:54:42] <AlexLehm> what is the best way to store state in a variable when accessing it via a lambda block in a test? I am currently using AtomicInteger and AtomicBoolean, but its probably that is too complicated

[19:54:57] <AlexLehm> and AtomicReference for String
