package net.named_data.jndn;

A class implements OnInterestCallback if it has onInterest, used to pass a callback to Face.registerPrefix or Face.setInterestFilter.
public interface OnInterestCallback {
  
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.
