Designing Legacy Code Wrapper Classes

Designing Legacy Code Wrapper Classes

In many systems, legacy C code is combined with newer C++ code. A common (yet wrong) practice is to wrap the C functions in a single C++ class and create a single instance thereof, which provides as its interface a series of operations mapped directly to the legacy functions. However, such a general wrapper class is not recommended. It allows indiscriminate access to a variety of unrelated operations. In addition, it isn’t really an object-oriented solution; rather, such a class is merely a collection of operations. A better design approach is to divide the legacy functions into meaningful, self-contained units and wrap each unit by a dedicated class. For example, instead of wrapping a bunch of legacy networking functions in a large class, it is advisable to group these functions according to specific protocols.

What is Metadata?

What is metadata? Well, It’s an odd concept to wrap your head around. Metadata is essentially the secondary layer of data that tracks details about the “regular” data. The regular
