Holy unknown construct Batman! I had no idea this was possible, and I
definitely would have used in in certain places!
Specifically, for callbacks where I need to set values to be retrieved
after the call.
void doSomething(SomethingSomething something) {
class MyCallback implements SomeCallbackInterface {
int calls;
boolean error;
public void somethingCalled() { ++calls; }
public void somethingErrored() { error = true; }
}
MyCallback cb = new MyCallback();
something.doSomethingwith(cb);
if (error) {
handleError();
}
if (cb.calls < 100) { smallBatch(); } else { largeBatch(); }
}
For example.
I have often instead created private static inner classes for this
purpose, but that pollutes the class IMO.
