A common requirement for high performance modules is to cache information that is expensive to obtain. The generic cache implementation in Momentum operates by having an upper bound on the number of elements to be stored in a cache, pushing out the least recently used item when an insert is made and the cache is full. You may optionally set a time-to-live for the cache; elements that have been stored in the cache for longer than the time-to-live will, periodically, be expired from the cache.
The APIs documented here relate to the cache list console command.
