ucar.nc2.grib.collection

Class GribCollectionImmutable

java.lang.Object

ucar.nc2.grib.collection.GribCollectionImmutable

All Implemented Interfaces:

Closeable, AutoCloseable, ucar.nc2.util.cache.FileCacheable

Direct Known Subclasses:

Grib1Collection, Grib2Collection, PartitionCollectionImmutable

@Immutable
public abstract class GribCollectionImmutable
extends Object
implements Closeable, ucar.nc2.util.cache.FileCacheable

An Immutable GribCollection, corresponds to one index (ncx) file. The index file has already been read; it is opened and the closed when a variable is first accessed to read in the record array (sa).

possible we could use the Proto equivalents, and eliminate GribCollectionMutable ?
