<br class="">
is it possible to modify the data packet inside the call beforeSatisfyInterest(shared_ptr<pit::Entry> pitEntry, const Face& inFace, const Data& data) ?<br class="">
<br class="">
Can I for example set a new type like this:<br class="">
<br class="">
data.getMetaInfo().setType(XY);<br class="">
<br class="">
I tried it, but it doesn't seem to work for me.<br class="">
<br class="">
Best regards,<br class="">
Klaus</div></div></blockquote><br class=""></div><div>Data packet is marked const in the method interface and it is incorrect to modify the data packet from NDN semantical view.
