title: C++: "Class namespaces"?
body: <p>If in C++ I have a class <code>longUnderstandableName</code>. For that class I have a header file containing its method declaration. In the source file for the class, I have to write <code>longUnderstandableName::MethodA</code>, <code>longUnderstandableName::MethodB</code> and so on, everywhere.</p>
  
  <p>Can I somehow make use of namespaces or something else so I can just write <code>MethodA</code> and <code>MethodB</code>, in the class source file, and only there?</p>
