POType Erasure rears its ugly head, how to circumvent?
text
Body
copied!<p>So I have this interface</p> <pre><code>public interface EventHandler<E extends EventObject> { public void handleEvent(E event); } </code></pre> <p>and I want to derive classes for it that handle events, like so:</p> <pre><code>public class WorkingHandler implements EventHandler<MouseEvent> { public void handleEvent(MouseEvent event) { //handle event } } </code></pre> <p>Above example works fine. But compiler won't let me implement EventHandler multiple times, due to the extremely frustrating Type Erasure.</p> <pre><code>public class NotWorkingHandler implements EventHandler<MouseEvent>, EventHandler<KeyEvent> { public void handleEvent(MouseEvent event) { //handle mouse event } public void handleEvent(KeyEvent event) { //handle key event } } </code></pre> <p>Several questions...</p> <ol> <li>Why does Java not allow Type Erasure? IIRC it is something to do with being compatible with earlier versions of Java, correct?</li> </ol> <p>EDIT: I mean why does Java have Type Erasure (had it the other way around) </p> <ol> <li><p>Is there any sort of "mod"/"extension" (for lack of a better word) or programming languages that allow me to get around Type Erasure? As I am not using older versions of Java I don't care about my code being compatible with older code.</p></li> <li><p>Are there any workarounds, within the Java language, that I can use to get around Type Erasure?</p></li> <li><p>If no, what are some alternate ways to code event handling in my program that keeps the compiler happy?</p></li> </ol>
