Detailed Description

Helper class hierarchy for acquiring variable of a certain type from a DDS. Will be passed into a static helper function within AggregationUtil. Interface class for the functor

Member Function Documentation

◆ clone()

virtual ArrayGetterInterface * agg_util::ArrayGetterInterface::clone ( ) const

pure virtual

Virtual constructor idiom

Implemented in agg_util::TopLevelArrayGetter, agg_util::TopLevelGridDataArrayGetter, and agg_util::TopLevelGridMapArrayGetter.

◆ readAndGetArray()

virtual libdap::Array * agg_util::ArrayGetterInterface::readAndGetArray	(	const std::string &	name,
		const libdap::DDS &	dds,
		const libdap::Array *const	pConstraintTemplate,
		const std::string &	debugChannel ) const

pure virtual

Find, constrain, read, and return an Array inside the DDS using the given name information (somehow, as specified in subclasses)

NOTE: this is a functor so sbuclasses may do searches, may dig into Grid's, etc in order to find the item it needs.

Parameters

name	name information on finding the correct Array note: this need not be the exact FQN, but can be interpreted by subclasses as "name.name" in the case of a Grid array, e.g.
dds	the DDS to search for the Array
pConstraintTemplate	if not NULL, use this Array as a template from which to copy constraints onto the returned Array prior to read.
debugChannel	if !empty(), the channel to print out debug information.
