public interface Size64

An interface for data structures whose size can exceed Integer.MAX_VALUE.

The only methods specified by this interfaces are size64(), and a deprecated size() identical to Collection.size(). Implementations can work around the type problem of Collection.size() (e.g., not being able to return more than Integer.MAX_VALUE) by implementing this interface. Callers interested in large structures can use a reflective call to instanceof to check for the presence of size64().

We remark that it is always a good idea to implement both size() and size64(), as the former might be implemented by a superclass in an incompatible way. If you implement this interface, just implement size() as a deprecated method returning Math.min(Integer.MAX_VALUE, size64()).
