title: What is the objective of an ObjectMapper?
body: <p>I don't understand why in Object Oriented development people are using some ObjectMapper class. Could you explain me what is the purpose of this kind of class? I'm also looking for documentation about it. I found a lot of information explaining how to create it but nothing about how and why to use it. Do you know where I can find a good article, blog on this (in C# if possible).</p>
  
  <p>A sub-question to be sure to understand. Are ObjectMapper something used in C++?</p>
  
  <p>Thank you.</p>
