DD::Image::InterestRatchet Class Reference

Public Member Functions
bool	interestedIn (Cache *cache)
void	addInterest (Cache *cache)
	~InterestRatchet ()

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.
