[ibr-dtn] Modifying bundle contents prior to forwarding through custom RouterExtension.

Hello,

I have the following:

- A bundle that has an extension block, which includes a list of entries.

I need to process the bundle as follows:

- Peek at the end of the list, and based on the value of a variable maintained in my RoutingExtension, pop off the end of the list, before forwarding the bundle.

My question is, where is the appropriate place to modify this bundle (i.e., pop the end of the list) ?

I currently peek at the list when a meta bundle is generated from the bundle.

However, I'm unclear what the appropriate place is to modify the bundle, so that is only changed once prior to forwarding.

Thanks, Tomasz
