In the message_filter package, there is a cache function that allows you to store data for a temporary amount of time. How would you access this cache properly? I understand that the function in message_filter says for doing a callback but how would go and create this callback function for the cache. I want to access different parts of the cache.

I think you are looking for that function:

std::vector< MConstPtr > getInterval (const ros::Time &start, const ros::Time &end) const

The callback is for new messages. I guess it's just there because it is a filter.
