ConceptThe asynchronous function (asynchronous funcation) is a higher level abstraction above the TPL, which really simplifies asynchronous programming. Abstraction hides the main implementation details, allowing programmers to make asynchronous programming easier without having to consider many important things.More contentTo create an asynchronous function, first annotate a method with the Async keywordNote: This article is read in the "C # multithreaded Programming Combat" after the written,

You run the sample program, and the program begins to traverse the directory and look for a specific file. Once the thread has checked itself out, it throws a Interruptedexception exception and continues executing the code of the Run () method, with multiple layers of recursive calls having no real effect on the result.The sleep () method in the Java Concurrency API

button click.Every element of MVC works separately. You can replace the push button with a toggle switch without changing your model and controller. The program still runs the same way as before, but there are some different things that appear in the interface. Or you can change the response of the button in your program without changing the interface. Separating these elements allows you to create a maintainable, rapidly updated program element.The MVC example class in the iphone:The @ View vi

A small problem in the iOS7 programming Cookbook example 15.8 The title of the 15.8 example in this book is Editing Videos on an iOS Device. The code function is to create a UIImagePickerController view that allows users to select a video file from the photo gallery and then edit the video in the UIVideoEditorController view, finally, get the path of the edited video file. It is very easy, but in the actual running code, it is found that when UIIma

ImageThe Background-position property contains two values, separated by commas. The first value determines the coordinates of the point on the x-axis, and the second value determines the coordinates on the y-axis. If only one value is given, then it represents the horizontal position, in which case the vertical position is set to 50%. Setting Background-position to 50% means placing the picture in the center of the browser window. 0% and 100%, respectively, place the picture in the upper-left an

,elem.text Since Iterparse is able to scan the elements and get the corresponding text. Then we can convert this function to a builder. The code is modified as follows: defXml_try (Element):Tag_indicate=[]Doc2=iterparse (R ' D:\test_source\rss20.xml ',(' Start ',' End ')) forevent,elem in doc2: if event = = ' start ' : Tag_indicate.append ( Elem.tag) if event = = ' end ' : if tag_indicate.pop () = = element: yield Elem.text __name__==' __main__

follows:E:\python2.7.11\python.exe e:/py_prj/python_cookbook/chapter5.pyCall Decorator_tryCall ExampleWrapperThe result of example.__name__ here is wrapper, not example. That is, the properties of the modified function have changed. Because the adorner can be equivalent to write Example=decorator_try (example). The return value of Decorator_try is wrapper. So the example attribute is then changed to wrapper. To eliminate this effect, we need to use wraps.After modifying the wrapper with wraps,
