Required operations not found (Reviewer Review)
You can add a list of operations for certain classes which subclasses should implement. If a class is derived from one of the named superclasses then a review item will be created if the required operation does not exist on the subclass.
Consequences
Required operations are often used for debugging or diagnostic information such as Dump and AssertValid in MFC for CObject based classes.
By not implementing these operations, derived classes will not provide any specific diagnostic information about themselves.
Strategy
Add the required operation or seek approval from a lead developer before ignoring these review item comments.
