Override the baseclass function

[pdk5]

hello,

In the base class, i have the following function (this is all in legacy code)

virtual const std::safemap<int, LPUMTSCELL>& GetUMTSCellList() = 0;

I am trying to create a new derived class, i am not using the above function. i just want to write a dummy override function. This is to enable instantiating the derived class.

	const safemap<int, LPUMTSCELL> GetUMTSCellList() 
	{	std::safemap<int, LPUMTSCELL> t; 
        LPUMTSCELL cell;
		t.insert(std::make_pair(1,cell));

		return t;
	}

Then i am getting the following error:
\TACPlanResultWizard.h(33,33): error C2555: 'TACPlanResultWizard::GetUMTSCellList': overriding virtual function return type differs and is not covariant from 'CWizBasePropSheet::GetUMTSCellList'

I just want to write a override function for test prupose. Please could you help with this compilation error ?

thankyou very much
pdk

const safemap<int, LPUMTSCELL> GetUMTSCellList() from derived implementation is different from

const safemap<int, LPUMTSCELL>& GetUMTSCellList() = 0;

See '&' from declaration of base class.
