Class GranuleAggregation

java.lang.Object
  edu.wisc.ssec.mcidasv.data.hydra.GranuleAggregation

All Implemented Interfaces:

MultiDimensionReader

public class GranuleAggregation
extends Object
implements MultiDimensionReader

Provides a view and operations on a set of contiguous data granules as if they were a single granule. This file needs to implement the same signatures NetCDFFile does, but for aggregations of consecutive granules.
