Public Member Functions

bool interestedIn (Cache *cache)

Detailed Description

If you create one of these, and pass it to 'Interest' then it will remember which Iops it has previously called addInterest on, and not do re-do these, thus saving time as addInterest involves contention

Interests are removed again when the InterestRatchet is destroyed.
