templates may not be ‘virtual’

Question

Given the code below, the compiler is showing a message pointing that error: templates may not be ‘virtual’. Does anyone have a suggestion on how to solve the bug?<

Answer 1

If you really need to make this method virtual, consider making CBar<> polymorphic and pass a base type in which isn't templated.

EDIT: something like this:

// non-templated base class
class BarBase
{
 // common methods go here..
};

template 
class CBar : public BarBase
{
 // implement methods from BarBase ...
};

template < class FOO_TYPE>
class CFoo{
    public:
        ...
        // now we take the base type, and this method does not need to be a template
        virtual void doSomething( BarBase const* ptrBar );
        ...
        virtual ~CFoo();
    protected:
        MyClass < FOO_TYPE > * m_pClass;
};

template < class FOO_TYPE >
void CFoo::doSomething( BarBase const* ptrBar ){
..
}
