Question

I am looking for memory leaks in my application and the profiler I am using tells me to look for these types of references but I don’t know what I’m looking for. Can some one please explain this?

Thanks,

Elliott

Answer 1

You can have synthetic back reference to an OUTER class, but not inner class instances.

e.g.

class Outer {

    class Inner {
    }

    static class Nested {
    }
}

In this example, Inner has a reference to the Outer class. Nested does not. If Outer is large this can mean you have can be holding onto an object you don’t need.

In short, make inner classes static if you can.
