Class DataDescriptor

java.lang.Object

ucar.nc2.iosp.bufr.DataDescriptor

public class DataDescriptor
extends Object

Essentially a TableB entry, modified by any relevent TableC operators. TableD has been expanded. Replication gets made into nested DataDescriptors, which we map to Structures (fixed replication) or Sequences (deferred replication). Most of the processing is done by DataDescriptorTreeConstructor.convert(). Here we encapsulate the final result, ready to map to the CDM.
