Re: [netcdf-java] Behaviour of NetCDF file cache in Java NetCDF libraries

OK, let's say I wanted to use the NetcdfDataset cache with things that
aren't NcML aggregations (e.g. an OPeNDAP dataset, or a single NetCDF
file).  As it stands, such datasets will never expire from the cache,
unless the maxElements parameter is exceeded.

Could I work around this by creating trivial NcML aggregations, then
opening the NcML wrapper through the cache?  I.e. an OPeNDAP dataset
might have a wrapper like this:

<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
  <aggregation recheckEvery="15 min">
    <netcdf location="http://myopendap.org/cldc.mean.nc"/>
  </aggregation>
</netcdf>

Will the recheckEvery parameter be respected in this case, or does the
aggregation have to be a joinExisting/joinNew?

Cheers, Jon
