Subject [jira] [Commented] (COLLECTIONS-473) AbstractCollectionDecorator.decorated() should not be used internally
Date Tue, 18 Jun 2013 20:24:20 GMT


Sebb commented on COLLECTIONS-473:

Yes, thanks; that makes it more future proof.

I think it's odd that the class uses decorated() internally, but the Javadoc does say so,
so I guess it needs to remain the way it is.

> AbstractCollectionDecorator.decorated() is used internally to access the collection.
> However, the method is not final, so subclasses could override it.
> Yet the field is also exposed (protected).
> This is inconsistent.
> Is there any use-case for overriding the collection to use a different one?
> If so, having direct access as well is likely to cause problems.
> I think it would be better to use the field directly internally.
> The class Javadoc says the calls are forwarded to the underlying collection, but that
is not strictly true if decorated() is overridden.
> If it is intended to allow this to be overridden, then the field needs to be protected
against arbitrary read/write access.
> The field should probably be made private with a setter for use by deserialization only.
