CodePorting C#2Java Application is a cloud based converter that has accomplished immense popularity because of its broad collection of supported C# language constructs. Its powerful engine parse and transforms thousand of C# souce code lines to java in few seconds. CodePorting has recently imrpoved its C#2Java engine and now its capable of converting C# source code having delegates in it to java. In C# programming language, delegate is a form of type-safe function pointer which is mostly used for call backs and event listener. Unfortunately, there is no delegate construct in Java so while converting C# code to Java, C#2Java engine intelligently converts the delegates to interfaces with the invoke method call by auto generating required code. Lets take an example of how codeporting engine converts C# delegates to java interfaces. C# Code: using System.Collections.Generic; using System; using System.Linq; public class Delegate { public static void Main(string[] arg) { Del handler = DelegateMethod; // Call the delegate. handler("Hello World"); } public delegate void Del(string message); public static void DelegateMethod(string message) { Console.WriteLine(message); } } Java Code: // ********* THIS FILE IS AUTO PORTED FROM C# USING CODEPORTING.COM ********* public class Delegate { public static void main(String[] arg) { Del handler = new Del() { public void invoke(String message) { delegateMethod(message); }}; // Call the delegate. handler.invoke("Hello World"); } public interface Del{ void invoke(String message); } public static void delegateMethod(String message) { System.out.printf(message); } }
