Method Detail

onInterest

void onInterest(Name prefix,
                Interest interest,

When an interest is received which matches the interest filter, onInterest is called.

Parameters:

prefix - The Name prefix given to registerPrefix or setInterestFilter (or directly to the InterestFilter constructor). NOTE: You must not change the prefix object - if you need to change it then make a copy.

interest - The received interest.

face - You should call face.putData to supply a Data packet which satisfies the Interest.

interestFilterId - The interest filter ID which can be used with Face.unsetInterestFilter.

filter - The InterestFilter given to registerPrefix or setInterestFilter, or the InterestFilter created from the Name prefix. The first argument, prefix, is provided for convenience and is the same as filter.getPrefix(). NOTE: You must not change the filter object - if you need to change it then make a copy.
