Leandro,
On xbase++ you can create them this way
http://databear.wordpress.com/2009/08/28/xbase-singleton-pattern/
Maybe you can adopt this to harbour.
Maurilio.
Thank you Maurilio
The author suggests to use class var and class methods to implement
singleton behaviour in xbase++. In most cases this aproach would work in
practice for sure in harbour too, but just as a workaround, because
Singleton pattern is about the class instantiation. The aproach suggested to
xbase++ would force the programmer to use the CLASS clause repeatedly to
every DATA and METHOD declaration, even when he wants for sure unique access
to all the members of a class.
I believe it would be usefull and simpler if one could just declare a class
as Singleton and have always acess to the same object instance when calling
the class by name.
What do you think?
Regards,
Leandro Damasio
