Dear all (esp. John),
I think I have been misunderstanding the intended behaviour of the
cache of NetCDF files (the one that's initialized with
NetcdfDataset.initNetcdfFileCache()).
What is the behaviour of the "periodic cleanup"? Does it remove
elements from memory only when the number of elements in memory
exceeds a certain number? Or does it also remove elements based on
their age?
The behaviour I would like is the latter - i.e. I would like to be
able to guarantee that the elements in the cache are no older than,
say, five minutes. But this isn't the behaviour I'm seeing: elements
seem to persist essentially for ever. So perhaps the former behaviour
is the correct one? In which case, how would you recommend I
implement the latter behaviour?
static public void initNetcdfFileCache(int minElementsInMemory, int
maxElementsInMemory, int hardLimit, int period) {
i think if you set
minElementsInMemory = 0
then it will remove all unlocked elements every period seconds. this
isnt exactly what you want, but its closer
