Meeting Report 10 December 1998 Three persons were present to the meeting of "Montreal Pattern User Group". The persons were: Regis Brochu regis.brochu@pwc.utc.com Jack Azoulay jack_a@iname.com Patrick Hodoul (Moderator) PatrickHodoul@Hotmail.com The purpose of this meeting was to study some of the "Creational Patterns" from GoF book. 1/ Singleton (GoF-127) We discussed mainly about the Singleton (GOF-127) pattern and found some questions and answers. The purpose of this pattern is to furnish a way to insure that a single instance of a class will be created. Here are some relevant issues discussed during the meeting: a/ How to destroy the singleton? The singleton destruction isn't study in the GoF book. b/ How to take care of multithreading? The multithreading aspects shall be considered due to possible concurrent accesses on Instance method of the singleton class. c/ How to suppress the switch statement in the sample p133? I think we should take few minutes on the next meeting to answer to this question? Next Meeting (01-13-99) The next meeting is planned for the Wednesday January 13, 1999 at 6 PM. The purpose is to study some of the "Creational Patterns" of the GOF book.
