About this episode

This episode discusses Java Carrier Classes and their implications for pattern matching, featuring insights from key figures in the Java community.

Carrier classes are Project Amber's current idea to extend some of records' benefits to regular classes. Probably the most important among them is deconstruction, which would allow classes to participate in pattern matching and reconstruction. In recent weeks, there have been two mails to the Amber mailing list that describe that idea, and in this episode we discuss them both as well as the evolution between them. We also hear why syntax discussions often provide negative value and get a sneak peak at what will likely be the next Project Amber language feature. Just ahead of the JavaOne speakers dinner, Nicolai Parlog sits down with Brian Goetz, Java Language Architect in Oracle's Java Platform Group, for this "Ask the Architect" episode of the Inside Java Podcast.
