TypedDatasetFactoryIF Interface for factories that wrap a NetcdfDataset with a subclass of TypedDataset
 

Class Summary
DataIteratorAdapter make an Iterator into a DataIterator
DatatypeIterator An abstract implementation for iterating over datatypes, such as PointObsDatatype, etc.
RadialDatasetSweep.Type A Type of RadialSweep.
StationImpl Implementation of Station
TypedDatasetFactory Manager of factories for TypedDatasets.
TypedDatasetImpl Superclass for implementations of TypedDataset.
VariableSimpleSubclass Adapt a VariableSimpleIF into another VariableSimpleIF, so it can be subclassed.
 

Package ucar.nc2.dt Description

Scientific data types package. The Point types have been superceded by the classes in package ucar.nc2.ft.

These are interfaces that define access to specialized "scientific datatype" datasets. There are three types of interfaces:

  1. Datatype: atomic datatype usually defined by its dimensionality and topology.
  2. Collection: a homogenous collection of atomic types, specifying the nature of the collection.
  3. Dataset: usually a Collection of a particular Datatype.

A TypedDataset and TypedVariable are lightweight abstractions of NetcdfDataset and Variable, which allows implementations that are not necessarily based on NetcdfDataset objects.
