All Implemented Interfaces:

Module

public class GradsGridSubsetter

extends GradsSubsetter

Streams subsets from gridded datasets.

Nested Class Summary

class	GradsGridSubsetter.DataMethods This is a wrapper class for a DataHandle, which implements operations that are dependent on configuration settings specific to the subset module, e.g., buffer size.
protected class	GradsGridSubsetter.Serializer A one-time-use class which serializes a particular data variable, with a particular set of bounds, to a particular stream.

Description copied from class: GradsSubsetter

Streams a subset to the output stream given, using the CEEvaluator given.

Specified by:

subset in class GradsSubsetter

Parameters:

useASCII - If true, print ASCII text; if false, send DODS/3.2 binary stream.

subsetLimit - maximum allowable size for the subset

Throws:

ModuleException - if subsetLimit bytes have already been written and there is still more data; or, if any errors occur during the subset operation
