Hi David,
Thanks for the suggestion of the singleton design . I tried to design a
template base class as follows :
Code:
namespace osgOpenCL
{
/**
This class helps to build the singleton design pattern.
Here you have full control over construction and deconstruction
of the object.
*/
Hi Jan,
This is not for reference counting but to not forget to delete the instance
when program end.
Regards
David

I wonder, why would you want a reference counting smart pointer for a
singleton? There will be

Do not forget to make all constructors private, though, otherwise you m

Hi Sajjadul,
There are nothing in OSG to do this, but make a class a singleton is really
straightforward.
- make constructor protected or private,
- add a static getInstance function
MyClass & getInstance()
{
static MyClass * myClass = new MyClass();
return *myClass;
}
then use it in yo
Hi Sajjadul,
There isn't any general signleton template or base class in the OSG, but
it's doesn't take much code to implement so when we use singleton's they
tend to get implemented locally in the code via a static access method.
Getting singleton's to work cross platform with thread safety on
