Description
Version: 2025-03 (4.35.0) Build id: 20250306-0812 JDK: jdk-21.0.6+7
When "Ignore in overriding and implementing method" is checked, unused parameters are ignored if the method is overriding or implementing an abstract method. If the method is implementing a functional interface as a method reference, eclipse shows the warning for any unused parameters.
In this example the parameter someParam is marked as unused, even though the method methodImplementation is used for implementating a functional interface.
public class Showcase {
@FunctionalInterface
interface MyFunction {
int apply(int someParam, int someOtherParam);
}
public static void main(String[] args) {
test(Showcase::methodImplementation);
}
private static void test(MyFunction func) {
var result = func.apply(42, 9001);
System.out.println("Result: " + result);
}
// someParam marked as unused, even if "Ignore in overriding and implementing method" is checked
private static int methodImplementation(int someParam, int someOtherParam) {
return someOtherParam;
}
}
