MSDN explains everything. I understand though that sometimes vanilla docs (particularly from MSDN) can be difficult to apply to your particular situation, so let’s go over your points. Question # 1: Is this assumption correct or the code below the await keyword is still executed? The code below the “await” keyword will only be executed … Read more
I think main problem is your assumption about the tackled problem are not quite so, since none of them are tackling the asynchronicity “problem”. The abstractions FRP main idea is propagation of change, think about accomplishing the same thing Excel does, where you define cells depending on each other in a cascade, and when one … Read more
Threadpool does not really fit into the same category as poll and epoll, so I will assume you are referring to threadpool as in “threadpool to handle many connections with one thread per connection”. Pros and cons threadpool Reasonably efficient for small and medium concurrency, can even outperform other techniques. Makes use of multiple cores. … Read more
Here’s an article from a few years ago that’s gung-ho on the technology, but I think the answer can be found in this quote: Why, for example, did Intel scrap its asynchronous chip? The answer is that although the chip ran three times as fast and used half the electrical power as clocked counterparts, that … Read more
If you need to create a future, you can use a Completer. See Completer class in the docs. Here is an example: Future<List<Base>> GetItemList(){ var completer = new Completer<List<Base>>(); // At some time you need to complete the future: completer.complete(new List<Base>()); return completer.future; } But most of the time you don’t need to create a … Read more
Can I do async constructor() No, that’s a syntax error – just like constructor* (). A constructor is a method that doesn’t return anything (no promise, no generator), it only initialises the instance. And, if not how should a constructor work that does this Such a constructor should not exist at all, see Is it … Read more
Update: Starting with Node 0.6 this post is obsolete, since stdout is synchronous now. Well let’s see what console.log actually does. First of all it’s part of the console module: exports.log = function() { process.stdout.write(format.apply(this, arguments) + ‘\n’); }; So it simply does some formatting and writes to process.stdout, nothing asynchronous so far. process.stdout is … Read more
Why don´t you create a kind of “Buffer” function to receive all messages from assyncronous entries and process them as FIFO (first-in, first-out)? This way you may keep the Assync characteristics of your ports and process them in sync mode.
Probably the best way to handle this is with a factory function, which calls a private constructor. In Dart, private methods start with an underscore, and “additional” constructors require a name in the form ClassName.constructorName, since Dart doesn’t support function overloading. This means that private constructors require a name, which starts with an underscore (MyComponent._create … Read more
While you can run a run loop manually (or, for asynchronous code that doesn’t require a run loop, use other waiting methods like dispatch semaphores), the “built-in” way we provide in playgrounds to wait for asynchronous work is to import the XCPlayground framework and set XCPlaygroundPage.currentPage.needsIndefiniteExecution = true. If this property has been set, when … Read more
