Utility class for asynchronous/coroutine style programming in UE4 C++

/**
* FAsyncQueue can be used to run asynchronous delegates in sequence, parallel and combinations of the above
*
* Use Add() to enqueue delegates matching FAsyncDelegate signature:
* a void function that accepts a single argument of another void function with no arguments.
*
* Static factories MakeSync, MakeSequence and MakeParallel can be used to wrap different type of delegates and
* delegate collections into a single FAsyncDelegate which can be enqueued with Add().

iclems / Firebase Lazy-Safe Iterator
Last active June 21, 2018 09:48
This snippet enables to iterate over a Firebase reference in a non-blocking way. If you need to iterate over a large reference, a child_added query may block your Firebase as it will query the whole data before iteration. With this snippet, children are retrieved one by one, making it slower / safer.
// By Clément Wehrung
function Iterator(queueRef, processingCallback) {
this.queueRef = queueRef;
this.processingCallback = processingCallback;
this.processed = {};
this.processNext();
}
Iterator.prototype.processNext = function() {
