日本語参考訳( ActionScript Thread Library 1.0 (そうめん) ドキュメント. ActionScript Thread Library 1.0 (そうめん) は、タスクシステムと Java のスレッドモデルをベースとした疑似スレッドライブラリです。 複雑で冗長になりがちな、イベント処理や非同期処理、リアルタイム処理を、分かりやすくスマートに記述することを可能にします。 もちろん、割り込みやキャンセル、例外処理もバッチリです。 スレッドを使って、イベントリスナー地獄から抜け出しましょう。 ※ActionScript Thread Library は、名前こそスレッドですが、実体はタスクシステムにスレッドモデルを搭載したものなので、 「スレッド」と考えるよりは、「タスクシステム」だと考えた方が理解が早いでしょう。 このドキュメントもその前提でお読みください。 1. スレッドライブラリの導入 1-1. はじめにこの処理をして、次にこの処理をして... ActionScript 3.0 (FlashPlayer) は、処理の流れがひとつしかない「シングルスレッド」で、かつイベントを介して処理を進める「イベント駆動」を採用しているため、 データのロード完了を待つ、ユーザーがマウスをクリックするのを待つ、といった非同期処理が入るととたんにコードが複雑になる傾向があります。 ActionScript Thread Library は、これを緩和するために、同時に複数の処理の流れ (すなわち複数のスレッド) が動く「マルチスレッド」を擬似的に実現し、かつ非同期処理が入る場合でも、 できるだけイベントのことを考えずに同期的に処理を書ける機構を提供します。

AIR Link Report visualizer | kahunaburger.
The Flex compiler has a rarely used feature called “link-report”. Using this option instructs the compiler to create a report of all symbols that went into the compiled application as well as a list of all external references. The Reducing SWF file sizes livedocs-page has more information about link reports. To enable it, you would either modify your Flex projects’ compiler settings: or you would use “-link-report output.xml” as an option on the mxmlc command line. The contents of the link report file look like this: Hmmm – not very easy to digest by just reading the file in a text-editor. I created an AIR application which can read, digest and visualize link-report files. After installing the LinkReportAIR application, you can use the “Browse …” button to select a link-report XML file on your system or alternatively just drag and drop an XML-file on the AIR application itself. You can download and install the AIR application using the badge below.
PEP 342 -- Coroutines via Enhanced Generators. PEP Index> PEP 342 -- Coroutines via Enhanced Generators Introduction This PEP proposes some enhancements to the API and syntax of generators, to make them usable as simple coroutines. It is basically a combination of ideas from these two PEPs, which may be considered redundant if this PEP is accepted: - PEP 288, Generators Attributes and Exceptions. The current PEP covers its second half, generator exceptions (in fact the throw() method name was taken from PEP 288). PEP 342 replaces generator attributes, however, with a concept from an earlier revision of PEP 288, the "yield expression". - PEP 325, Resource-Release Support for Generators. PEP 342 ties up a few loose ends in the PEP 325 spec, to make it suitable for actual implementation.
Motivation Coroutines are a natural way of expressing many algorithms, such as simulations, games, asynchronous I/O, and other forms of event- driven programming or co-operative multitasking. Specification Summary Specification: Exceptions and Cleanup 1. Caliburn: A Client Framework for WPF and Silverlight. IResult is one of the most powerful features of Actions. Any action can return an instance of IResult or IEnumerable IResult enables handling many difficult programming scenarios with ease, mainly asynchronous programming. Here's an example of what you can do: public IEnumerable<IResult> Login(string username, string password) { var authenticator = new AuthenticateResult(username, password); yield return authenticator; if(! Note: "Show" is a static factory for instances of IResult. It is not included as part of the Caliburn v1.0 or 1.1, but it will be part of the ShellFramework in v2.0.
Each yield statement returns some instance of IResult which Caliburn executes. To create your own IResult simply implement the interface on your own class. This is just one example of the endless possibilities and was developed for a specific application where this type of interaction was common. Liber.sourceforge.net/coroutines.rb. Index.

Heavy Industries: public Git repositories - chiral.git/summary. Package Index : multitask 0.2.0. API docs for “kiwi.tasklet” Pseudo-thread (coroutines) framework This module adds infrastructure for managing tasklets. In this context, a tasklet is defined as a routine that explicitly gives back control to the main program a certain points in the code, while waiting for certain events. Other terms that may be used to describe tasklets include coroutines, or cooperative threads. The main advantages of tasklets are: Eliminates the danger of unexpected race conditions or deadlocks that happen with preemptive (regular) threads; Reduces the number of callbacks in your code, that sometimes are so many that you end up with spaghetti code. The fundamental block used to create tasklets is Python's generators.
The neat thing about generators are not the iterators themselves but the fact that a function's state is completely frozen and restored between one call to the iterator's next() and the following one. A single Message object, with a correctly set dest parameter. From kiwi import tasklet tasklet.run(my_task(x=0)) Denis / gevent / source – Bitbucket. Event – Notifications of multiple listeners — gevent v0.13.5 documentation. Class gevent.event.Event A synchronization primitive that allows one greenlet to wake up one or more others. It has the same interface as threading.Event but works across greenlets. An event object manages an internal flag that can be set to true with the set() method and reset to false with the clear() method. The wait() method blocks until the flag is true. is_set()isSet() Return true if and only if the internal flag is true. set() Set the internal flag to true. Clear() Reset the internal flag to false. Wait(timeout=None) Block until the internal flag is true.
When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). Return the value of the internal flag (True or False). rawlink(callback) Register a callback to call when the internal flag is set to true. callback will be called in the Hub, so it must not use blocking gevent API. callback will be passed one argument: this instance. value ready()
Chapter 1. Boost.Coroutine. Code - Mordor. Mordor allows you to focus on performing a logical task, instead of deciding how to make that task conform to a specific threading/event model. Just because local disk I/O will block and should be performed in a thread pool while network I/O should be performed using an event based callback design, doesn't mean you can't do them both in the same function. Mordor allows you to do just that. For example, here's a complete program to read a file from disk, and send it to a socket on the network: Forward a file from disk to a socket This program is quite simple. Looking at this code, we can see that there is only a single thread, which is all fine and dandy if this is all we're doing. Forward n files from 4 disk threads to n sockets Here, we re-factored most of main into doOne, but other than that it is nearly identical.
The IOManager is the object used for non-blocking network I/O, and so is passed to the Socket when it is created. Exceptions thrown across stack-swapped threadpool switching. Pieces/Xtalion/Coroutines/Yield.cs at master from yevhen/Servelat-Pieces - GitHub. Coroutine. Computer software component They have been described as "functions whose execution you can pause".[1] Melvin Conway coined the term coroutine in 1958 when he applied it to the construction of an assembly program.[2] The first published explanation of the coroutine appeared later, in 1963.[3] Definition and types[edit] There is no single precise definition of coroutine. In 1980 Christopher D. The values of data local to a coroutine persist between successive calls;the execution of a coroutine is suspended as control leaves it, only to carry on where it left off when control re-enters the coroutine at some later stage.
Besides that, a coroutine implementation has 3 features: the control-transfer mechanism. asymmetric coroutines usually provide keywords like yield and resume. Comparison with[edit] Subroutines[edit] Any subroutine can be translated to a coroutine which does not call yield.[7] Here is a simple example of how coroutines can be useful. Threads[edit] Generators[edit] Common uses[edit] Iterators and generators - MDC Doc Center. Processing each of the items in a collection is a very common operation. JavaScript provides a number of ways of iterating over a collection, from simple for and for each loops to map(), filter() and array comprehensions. Iterators and Generators, introduced in JavaScript 1.7, bring the concept of iteration directly into the core language and provide a mechanism for customizing the behavior of for...in and for each loops. Iterators An Iterator is an object that knows how to access items from a collection one at a time, while keeping track of its current position within that sequence.
In JavaScript an iterator is an object that provides a next() method which returns the next item in the sequence. Once created, an iterator object can be used either explicitly by repeatedly calling next(), or implicitly using JavaScript's for...in and for each constructs. Simple iterators for objects and arrays can be created using the Iterator() function: Iterator() can be used with arrays as well:
Caliburn.Micro Soup to Nuts Pt. 5 – IResult and Coroutines. Before our WP7 detour, we were deep in the thick of Actions. I mentioned that there was one more compelling feature of the Actions concept called Coroutines. If you haven’t heard that term before, here’s what wikipedia* has to say: Here’s one way you can thing about it: Imagine being able to execute a method, then pause it’s execution on some statement, go do something else, then come back and resume execution where you left off.
This technique is extremely powerful in task-based programming, especially when those tasks need to run asynchronously. For example, let’s say we have a ViewModel that needs to call a web service asynchronously, then it needs to take the results of that, do some work on it and call another web service asynchronously. Finally, it must then display the result in a modal dialog and respond to the user’s dialog selection with another asynchronous task. First, notice that the Action “GoForward” has a return type of IEnumerable<IResult>.
[Advertisement] Fun with Rx. Download source code - 292 KB Introduction This article is an exploratory look into the Microsoft DevLabs project called Reactive Framework (Rx for short). I feel kind of weird saying this, but the demo solution that comes with this article will provide you nothing re-usable at all, but what it should hopefully do is give you an understanding of how Rx works. Prerequisites As the Reactive Framework is still effectively a DevLabs project, and not entirely in the mainstream .NET Framework (yet), you are still required to download and install an MSI, which you can find at the following URL: where the demo app relies on the "Rx for .NET 4.0" option being downloaded and installed. The other thing you will need is Visual Studio 2010, and .NET 4.0 Rx Rx is a library for composing asynchronous and event-based programs using observable collections. - Reactive Framework home page up on date 07/09/10.
Discussing the Demo Apps RxDraw (.NET 4.0) Frictionless WCF service consumption in Silverlight - Part 2: Fixing the "All Is Async" Problem. Download source code - 31 KB Introduction In my previous article, I've shown how to consume a WCF service in a Silverlight application without static proxy generation, by creating its asynchronous twin interface. This article will show how to greatly simplify code which calls WCF services asynchronously. While the solution will be presented in the context of Silverlight applications, you can easily use it in any other code which deals with asynchronous method calls.
Background Let's first see an example application which I'll be using to present the solution.
