class CSemModel : public CBase
{
private:
CArrayPtrFlat iStar;
};


i) It is not good practice to have a C-class directly embedded inside another C-class, a pointer to the embedded C-class should be used:

class CSemModel : public CBase
{
...
private:
CArrayPtrFlat* iStar;
};

ii) Although not unknown, it is unusual to have an array of pointers to T-classes (especially T-classes as small as TStar). The T-classes have to live somewhere so they might as well live in the array itself. So the code changes to:

class CSemModel : public CBase
{
...
private:
CArrayFixFlat* iStar;
};

iii) The class definition should use the most abstract definition of the storage structure (in this case CArrayFix):

class CSemModel : public CBase
{
...
private:
CArrayFix* iStar;
};


Of course the implementation still uses CArrayFixFlat:

void CSemModel::ConstructL()
{
iStar = new (ELeave) CArrayFixFlat(EGranularity);
}

This allows the implementation to change from using CArrayFixFlat to CArrayFixSeg without changing the header file.
