Aggregation.Dataset

protected Aggregation.Dataset(MFile mfile)

Aggregation.Dataset

protected Aggregation.Dataset(String cacheLocation,
                   String location,
                   String id,
                   EnumSet<NetcdfDataset.Enhance> enhance,
                   FileFactory reader)

Dataset constructor. With this constructor, the actual opening of the dataset is deferred, and done by the reader. Used with explicit netcdf elements, and scanned files.

Parameters:

cacheLocation - a unique name to use for caching

location - attribute "location" on the netcdf element

id - attribute "id" on the netcdf element

enhance - open dataset in enhance mode, may be null NOT USED

reader - factory for reading this netcdf dataset; if null, use NetcdfDataset.open( location)
