running code when two events have triggered
- by Evert
This is mostly a language-agnostic question.
If I'm waiting for two events to complete (say, two IO events or http requests), what is the best pattern to deal with this. One thing I can think of is the following (pseudo js example).
request1.onComplete = function() {
req1Completed = true;
eventsCompleted();
}
request2.onComplete = function() {
req2Completed = true;
eventsCompleted();
}
eventsCompleted = function() {
if (!req1Completed || !req2Completed) return;
// do stuff
}
Is this the most effective pattern, or are there more elegant ways to solve this issue?
