C#的委托 Action<>和Func<>

由 拟墨画扇 提交于 2019-12-15 21:16:08
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 其实他们两个都是委托【代理】的简写形式。 一、【action<>】指定那些只有输入参数，没有返回值的委托 Delegate的代码： [csharp] public delegate void myDelegate(string str); public static void HellowChinese(string strChinese) { Console.WriteLine("Good morning," + strChinese); Console.ReadLine(); } myDelegate d = new myDelegate(HellowChinese); d("Mr wang"); 用了Action之后呢： [csharp] public static void HellowChinese(string strChinese) { Console.WriteLine("Good morning," + strChinese); Console.ReadLine(); } Action<string> action = HellowChinese; action("Spring."); 就是相当于省去了定义委托的步骤了。 二、func<> 这个和上面的那个是一样的，区别是这个有返回值！

Assign 'value expression' in place of 'method expression' in JSF

问题 In my composite component, I iterate a list<list<javaDetailClass>> . I get all my <h:commandButon> attribute's values through value expression like #{iterator.value} . But the problem comes with attribute action , where action accepts only method expression . whereas I can assign only value expression there, resulting in MethodNotFoundException <cc:interface> <cc:attribute name="formElements" /> </cc:interface> <cc:implementation> <c:forEach items="#{cc.attrs.formElements}" var="element"> <c

Action of <h:commandButton> not getting invoked when “disabled=true” is set

由 a 夏天 提交于 2019-12-14 03:17:57
问题 I want the Submit button to be enabled when the T&C checkbox is checked. Though my written logic is working alright the action of h:commandButton is not getting invoked even after it is enabled after checking the checkbox. Initially the button is disabled. The code works fine if I remove the disabled="TRUE" attribute but it doesn't serve the purpose. Here is my code : <script type="text/javascript"> $(document).ready(start); function start() { $('.testing').click( function() { if ($(document

@selector and other class (Objective-C)

由 微笑、不失礼 提交于 2019-12-14 01:32:29
问题 Inside an object I use NSMenu's addItemWithTitle:action:keyEquivalent: to create NSMenuItems. The problem is that I wish to call a method on another object as action. The action: part takes an @selector as parameter and I don't know how to use this to call methods on other objects. I could create a method inside the object creating the NSMenu and then from that object I could call the method I would like to call on another object.. But then I don't know any good naming convention for that.

Or is there be the timeline API which i can put the action of actor on several specific time points? 回答1: not if
