In the case of two singletons A,B where an instance of B is created in the constructor of A and the constructor of B needs to have a reference to A it would also be possible to to use A.getInstance(), if A.getInstance() would return the not yet fully constructed A; otherwise a new instance of A would be created, leading to an infinite loop.
I would however prefer to pass 'this' from A to the constructor of B; without arguments X.getInstance() should of course behave as it is now. ibu ----- Original message ----- From: [EMAIL PROTECTED] ([EMAIL PROTECTED]) To: qooxdoo Development <qooxdoo-devel@lists.sourceforge.net> Date: Monday 09 April 2007 08:40 (UTC+1) Subject: [qooxdoo-devel] 0.7-alpha2 singletons: getInstance() arguments > experimenting with 0.7-alpha2 I found that for a singleton > arguments of getInstance() are not passed to the constructor.
