Question about Loki::Singleton |
Hello All!
This is example of code:
//////////////////////////////////////////////////////////////////////////////////////////////////
#ifndef A_H_
#define A_H_
#include <Loki/Singleton.h>
#include <Loki/SmartPtr.h>
#include <iostream>
class A
{
public:
A() { std::cout << "A constructor" << std::endl;}
~A() { std::cout << "A destructor" << std::endl;}
};
typedef Loki::SingletonHolder<
Loki::SmartPtr<A>,
Loki::CreateUsingNew,
Loki::NoDestroy,
Loki::SingleThreaded
APtrSingleton_t;
#endif
//////////////////////////////////////////////////////////////////////////////////////////////////
I can use APtrSingleton_t::Instance() in my program, but it's very
uneasily.
How to define (short) alternative name of APtrSingleton_t::Instance()?
Thanks!
.

A* x() {
return APtrSingleton_t::Instance();
}
Then whenever you want the instance, just do:
A* a = x();
Not very useful if you ask me, though.

I'm not just a number. To many, I'm known as a string...

You could create a macro (yuck!), an inline function, or a local
reference (my preference):
Loki::SmartPtr<A>& ptr = APtrSingleton_t::Instance();
Cheers! --M
