Detailed Description

Base class for subclasses of libdap::Array which perform aggregation on a list of AggMemberDatasets when asked.

Definition at line 51 of file ArrayAggregationBase.h.

Constructor & Destructor Documentation

◆ ArrayAggregationBase() [1/2]

agg_util::ArrayAggregationBase::ArrayAggregationBase ( const libdap::Array & granuleProto,
AMDList memberDatasets,
std::unique_ptr< ArrayGetterInterface > arrayGetter )

Construct the base class using the given parameters. Used for join aggregation concrete subclasses.

Parameters
granulePrototemplate describing the data array of for a granule (member) of the join agg. Note: for joinExisting the array size may not be correct!
memberDatasetsthe granules to use in the agg
arrayGetterunique_ptr to the data array getter for the variable. Note the unique_ptr ref is sunk by the ctor so don't delete/release from the caller.
Returns

Member Function Documentation

◆ getArrayGetterInterface()

const ArrayGetterInterface & agg_util::ArrayAggregationBase::getArrayGetterInterface ( ) const
protected

Accessor for subclasses Note this is protected, so not const! Subclasses may mutate the return hence this, but should not delete it, hence the reference.

Definition at line 168 of file ArrayAggregationBase.cc.

◆ getDatasetList()

const AMDList & agg_util::ArrayAggregationBase::getDatasetList ( ) const

Get the list of AggMemberDataset's that comprise this aggregation

Definition at line 146 of file ArrayAggregationBase.cc.

◆ getGranuleTemplateArray()

libdap::Array & agg_util::ArrayAggregationBase::getGranuleTemplateArray ( )
protected

Accessor for subclasses Note this is protected, so not const! Subclasses may mutate the return hence this, but should not delete it, hence the reference.

Definition at line 161 of file ArrayAggregationBase.cc.

◆ operator=()

ArrayAggregationBase & agg_util::ArrayAggregationBase::operator= ( const ArrayAggregationBase & rhs)

Definition at line 78 of file ArrayAggregationBase.cc.

◆ printConstraints()

void agg_util::ArrayAggregationBase::printConstraints ( const Array & fromArray)
protected

Print out the constraints on fromArray to the debug channel

Definition at line 153 of file ArrayAggregationBase.cc.

◆ ptr_duplicate()

ArrayAggregationBase * agg_util::ArrayAggregationBase::ptr_duplicate ( )
override

virtual constructor i.e. clone

Definition at line 90 of file ArrayAggregationBase.cc.

◆ read()

bool agg_util::ArrayAggregationBase::read ( )
override

Base implementation that works for both joinNew and joinExisting. Sets ups constraints and things and then calls the subclass helper readAndAggregateGranules() for the specialized subclass behaviors.

Note
This implementation of read() will read all of the data for an aggregated variable. Child classes of this class can use specialized versions of serialize() to implement a different behavior so that data that are read in parts (e.g. slices of an Array) can also be written in parts. This can reduce access latency.
Exceptions
Canthrow BESError, minimally
Returns
whether it works

Definition at line 101 of file ArrayAggregationBase.cc.

◆ readConstrainedGranuleArraysAndAggregateDataHook()

void agg_util::ArrayAggregationBase::readConstrainedGranuleArraysAndAggregateDataHook ( )
protectedvirtual

The meat of the subclass impl of read(). Called from read() once this base class state is ready for the granule data.

Reimplemented in agg_util::ArrayAggregateOnOuterDimension, and agg_util::ArrayJoinExistingAggregation.

Definition at line 201 of file ArrayAggregationBase.cc.

◆ transferOutputConstraintsIntoGranuleTemplateHook()

void agg_util::ArrayAggregationBase::transferOutputConstraintsIntoGranuleTemplateHook ( )
protectedvirtual

subclass hook from read() to setup constraints on inner dims correctly

Reimplemented in agg_util::ArrayAggregateOnOuterDimension, and agg_util::ArrayJoinExistingAggregation.
