We are interested in getting information only for inner classes, which is determined by checking if the parsed class matches any of the inner classes in its inner class array. If the parsed class is not an inner class, then it is ignored. When a parsed class is an inner class, the accessibility information for the parsed class is overwritten, and the parsed class is marked as an inner class.
