Description
There are several valuable methods in Name class that are not currently available:
isPrefixOfcompare(int, int, Name, int, int)getSubNamegetSuccessor
For documentation and reference implementation refer to ndn-cxx.
Agree they're useful. Just let us know priority of this, and for what libraries first.
I would use them in Python and Java

Yes, I guess I missed it.

Hi Alex. The ndn-cxx doc for compare(int, int, Name, int, int) says "This is equivalent to this->getSubName(pos1, count1).compare(other.getSubName(pos2, count2))". But getSubName treats a negative position as indexing back from the end of the name. However, compare does not do this.
In jNDN, etc. I will go ahead and support negative indexes in compare. Does that sound right? Should I submit an ndn-cxx issue either to fix the doc for compare, or to support negative positions?
I don't have much opinion. The idea for compare was to have an optimized version to compare parts of the names. Implementing negative indices can help simplifying code (good), but will have a minor performance hit (could be ok).
Then I'll support negative indexes. An application could easily compare the last two components of one name with the last two of another.

Added isPrefixOf, getSuccessor and compare(int, int, Name, int, int) to NDN-CPP, PyNDN, NDN-JS and jNDN. Merged to the master branch.
