re-assigning a non-pointer object variable

[sgiri1981]

Hi All,

I am working on a project that has a large base class that uses a baseUtil class:

Class BaseClass
{
public: 
    BaseUtil m_baseUtil;
}

I have derived both these classes: DerivedClass and DerivedUtil

Class DerivedClass : public BaseClass
{
public: 
    DerivedUtil m_derivedUtil;
}

The BaseClass and BaseUtil are huge classes; BaseClass calls BaseUtils at multiple instances. I am inheriting most of the features and making very few changes in the derived classes.

My objective is: I want BaseClass to use DerivedUtil instead of BaseUtil.
The problem is: BaseClass is using a regular object, and not pointer, for BaseUtil. Further, the BaseUtil has disabled copy constructor and assignment operator with the following code in the "private" section

    BaseUtil(const BaseUtil&right);
    BaseUtil& operator=(const BaseUtil&right);

Is there an elegant solution, or should I just make changes in BaseClass and BaseUtil rather than using inheritance and polymorphism.

Thanks for looking.
best,
SG
