This week's book giveaway is in the NodeJS forum. We're giving away four copies of Serverless Applications with Node.js and have Slobodan Stojanovic & Aleksandar Simovic on-line! See this thread for details.
In JPA Pro 2nd edition, figure 9-1, it says Fetch is a child interface of Path. But I don't think so.
As I check on the API, Fetch's parent interface is FetchParent. Fetch does not extend any other interfaces.
Please refer to the following attached diagram from the book.
