You’ll find Encapsulated Context in chapter 3, this version is slightly different from the online version - thanks to Addison-Wesley’s sub-editing and the editors review process.
So, rush out and buy the book!
As for my reward... I get little more than the fame of having chapter 3 of a major patterns book, Addison-Wesley should be sending me two copies. That’s it.
Its nearly four years since I started to write the pattern so I think some celebration is in order. I’ll let you know when I get the books and I’ll arrange some celebratory drinks.
