      }
    ],
  }
}

abstract class TestClass {
  abstract bar(): void;
  foo(): void {}
}

Expected Result

No error

Actual Result

  3:3  error  Member foo should be declared before all private instance method definitions  @typescript-eslint/member-ordering

Additional Info

Abstract methods are not necessarily private methods. There are two issues here:

1. There is no private method in this class so the error message doesn't make sense.
2. Nowhere in the settings is the order between abstract & regular methods defined so it shouldn't be enforced.

This came up when I tried to migrate my TSLint config containing:

    "member-ordering": [
      true,
      "public-before-private",
      "static-before-instance",
      "variables-before-functions"
    ],

and I failed due to errors around abstract methods handling.
