If you simply need to store additional information alongside each/specific PIT entries that your strategy uses, NFD has a mechanism for that. You just need to implement a class derived from StrategyInfo and add it/look it up from the entry when needed. Example of this is in the AccessStrategy (<a href="https://github.com/named-data/NFD/blob/master/daemon/fw/access-strategy.hpp#L73" class="">https://github.com/named-data/NFD/blob/master/daemon/fw/access-strategy.hpp#L73</a>), so you can do similar stuff.<div class=""><br class=""></div><div class="">As for the error, you have used a wrong member class selector. With "." you are trying to access members of "shared_ptr" class. If you replace with "->", you will be access the right thing.</div><div class=""><br class=""></div><div class="">-</div><div class="">Alex<br class=""><div><br class=""><blockquote type="cite"
