Are anonymous methods defined inline?

问题 Are anonymous methods defined inline ? In the example below, the delegate object "d" is having reference of an anonymous method, which is accessing "x" variable which is defined in the Fun method. The scope of "x" should be limited to Fun method, but when we call MyFun, which invokes the delegate passed as parameter and increments the value of "x". The output comes out to be "6", how does this happen ? How the value of "x", or in first place "x" variable itself was available in the anonymous

How to specify the default scope in Spring's applicationContext.xml to request scope?

问题 I want to make all beans request scoped by default, however the Spring documentation says that the default scope is Singleton. (sections 3.4.1 and 3.4.2 http://static.springsource.org/spring/docs/2.5.x/reference/beans.html) I want to declare the default scope to be request scoped. This is the closest thing I have found so far -- it's a defect that has not been touched in some time. jira.springframework.org/browse/SPR-4994?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel#issue

What's the best practice for writing an “execute only” Python module?

由 妖精的绣舞 提交于 2020-01-15 09:34:12
问题 I have a Python module that is intended exclusively for running as a script and never as something that should be imported, and I'd like to enforce (and communicate) that intention in my code. What is the best practice for accomplishing this? I can imagine a few options such as wrapping the whole file in if __name__ == '__main__': # All the code in the module or aborting at the start if __name__ != '__main__': exit() # All the code in the module perhaps with a warning if __name__ != '__main__

Variables in a Javascript module visible outside of it?

由 北慕城南 提交于 2020-01-15 04:55:21
问题 To start, I'm coming from a .NET world, where there are static classes (C#, also known as modules in VB) and instance classes - those you can instantiate. This question is about Javascript, where I'm trying to recreate the pattern I already know and make a module / static class. Here is the code: var MyModule = { variable1: 0, variable2: 1, method1: function() { //code goes here }, method2: function() { //mode code goes here }, method3: function() { //and some more just to prove the pattern }

Javascript : pattern to avoid global variables

由 放肆的年华 提交于 2020-01-15 03:47:06
问题 I think this is a simple question. Imagine you have a page that initializes a JS variable named channel : <html> <script> $(document).ready(function() { ... var channel = new Channel(); channel.send("helo"); } </script> <body> <div id="placeholder"></content> </body> </html> The page also contains a div with id="placeholder" which content is loaded using AJAX. That external content have to access the channel variable. Is there any good practice or advice about where to store the variable? The

scope of julia variables: re-assigning within a loop in open expression

由 回眸只為那壹抹淺笑 提交于 2020-01-15 03:16:09
问题 I am struggling with re-assigning a variable in a loop in Julia. I have a following example: infile = "test.txt" feature = "----" for ln in 1:3 println(feature) feature = "+" end open(infile) do f #if true # println(feature) # feature = "----" println(feature) for ln in 1:5 #eachline(f) println("feature") #fails here println(feature) # because of this line: feature = "+" end end It fails if I do reassignment within the loop. I see that the issue with the variable scope, and because nested

Spring Event Handling for prototype components

由 生来就可爱ヽ(ⅴ＜●) 提交于 2020-01-14 14:33:09
问题 Let say I have two components X and Y, where X is singleton and Y is not. when I publish XUpdateEvent, there is no problem, I can catch the event. However, for YUpdateEvent's I cannot catch events. Spring creates new instances for each fired event, not using the already created ones. So, Should I need to write a custom scope? or EventListener has settings? To illustrate: @Component public class X{ @EventListener public void onUpdate(XUpdateEvent event){ // fine. } } @Component @Scope(

问题 How can I go about setting the scope: @Component @Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype") in XML, instead of using @Scope annotation? 回答1: If you want XML based configuration then you can do it in following way:- <bean id="YOUR_BEAN_ID" class="YOUR_FULLY_QUALIFIED_CLASSNAME" scope="prototype"> <aop:scoped-proxy proxy-target-class="true"/> </bean> 回答2: You can include Bean definition in xml file as below <bean id="Simple" class="com.example.Simple" scope="prototype
