How to create instance of class that get data from 2 another instance?

[Suliman via Digitalmars-d-learn]

class parseConfig
{
	string dbname;
	string dbuser;
	string dbpass;
	string dbhost;
	string dbport;
	uint status;

this()
	{
	
auto checkLinkCode(string link) // we need to check all links to 
be sure if they are alive
{
....
	return status;
}
.............
	if (checkLinkCode(emsc_csem) == 200)
	{
		auto seismodownload = new seismoDownload(emsc_csem, this); 
//here
		seismodownload.parse();
	}

		
}
}


I know that in С# I can pass to function, and this would be point 
of class from where it's call (Here is parseConfig). Is it's 
possible to do something similar in D?
