How to Rename Namespace?

23 11 2008


Namspaces are introduced to have logical grouping of classes. But as the framework grows you could often find that the namespace length grows which make the usage more difficult.

For instance, one namespace i’ve encountered is like this –

namespace Company
{
    namespace Product
    {
        namespace Communication
        {
            namespace Event
            {
                class CEventEx
                {
                };
            };
        }
    };
};

How much I’ve to go inside to address a class? Well, in big frameworks this kind of deep hierarchy is unavoidable. But, its a fact that it causes trouble to developer who uses it. Well, is there any idea to avoid that?


Well, you can rename the namespace to much more smaller one! Have a look at the code snippet below.

// Rename the namespace
namespace ThirdPartyEvent = Company::Product::Communication::Event;
...
// Create the object by using renamed namespace.
ThirdPartyEvent::CEventEx objEvent;


There are still a lot of gems inside C++. isn’t it? 😉
