It seems that the names of the patterns have been changing. The patterns catalog on Sun's site have names like "value object", "aggregate entity" and "decorating filter". However, in the 2nd edition of core patterns they use the names "transfer object", "composite entity" and "intercepting filter". So are these the new "correct" names for the patterns? Can we use these interchangeably? It seems that the concepts of each pattern are still the same. -Ray
Thanks Pradeep. That solves the question of the value object. There is still the case of the other two classes though. I also wanted to ask - as these patterns are evolving what is the most source? The core patterns 2nd edition is not posted on the web yet but seems to be the most recent 'official' source.
I am glad you asked this question because I have been wondering about this too. On page xxviii of the second Ed. I see the URL of the patterns interst group. I would really be interested in knowing if you find any discussion of this over there. [ October 15, 2003: Message edited by: Rufus BugleWeed ]
