|Design| C++ getInstance

如果你要獲取特定的物件

就可以使用 getInstance()

這樣比全域變數看起來舒心一點

e.g. ————————————————————————

// test.h
class SomeService
{
public:
static SomeService &GetInstance();

}

// test.cpp
SomeService& SomeService::GetInstance()
{
static SomeService instance;
return instance;
}

————————————————————————
