java.lang.Object

ucar.nc2.grib.coord.SparseArray<T>

@Immutable
public class SparseArray<T>
extends Object

Store objects of type T in a sparse array. Conceptually a multidim array with shape[n] and totalsize. Stored as track[totalsize] = {0 = missing, else = index+1 into List content} So we dont have to store missing Ts.
