[ndnSIM] List all Installed Prefix on a Node from App

[Spyridon (Spyros) Mastorakis]

Hello Hitesh,

I suggested this particular solution, because you stated that you wanted to get the prefixes on the application layer. However, if this is not a restriction, Alex’s solution is probably more convenient. But again, this is up to you to decide. :)

But for sure, I agree with Alex that there are multiple ways for the thing that you want to do.

However, Alex has suggested iterate over FIB which is also a good option. But, I will prefer better to store configured prefix information on node with application pointer/indexed.  So, there could be a scenario where many applications can be installed on same node.

Then, you can simply aggregate this object with the node object and call the “getPrefix" method, whenever you want, in order to extract the prefix. I think that this applies both to producers and consumers. :)
