rx java - Will combinelatest trigger doOnUnsubscribe of its children -

not sure if combined observable delegates doonunsubscribe sources.

if not there simple way trigger unsubscribles of children?

in code:

observable o = observable.combinelatest(o1, o2); 

if triggers unsubscribe of o trigger unsubscribe of o1 , o2?

not sure mean.

unsubscription propagated both o1 , o2 if want perform custom actions, have use doonunsubscribe on relevant parties:

observable<t> o = observable.combinelatest(     o1.doonunsubscribe(() -> { }),     o2.doonunsubscribe(() -> { })) .doonunsubscribe(() -> { });  o.take(1).subscribe(); 

but note these chain-global (instead of per-subscriber) actions , second subscription/unsubscription o may call them again. if need per-subscriber resource management, @ using operator.
