FolderMan Instance Creating

Hi,

i noticed that whenever the class FolderMan is used the function instance() is called to create an instance of the class, so when i went the the FolderMan class i found the following lines of code:

FolderMan *FolderMan::_instance = 0;

    ASSERT(!_instance);
       _instance = this;

    FolderMan *FolderMan::instance()
    {
        return _instance;
    }

im not an expert in C++ but that code looks a lot like singleton, is that correct?

and if i wanted to use the class “FolderMan” anywhere else in the code i just need to follow the same approach which is: FolderMan *folderMan = FolderMan::instance(); correct?
