Detailed Description

A reduction on tabular data over time steps.

Tabular data from each time step is collected and concatenated into a big table.

Member Function Documentation

◆ get_class_name()

const char* teca_table_reduce::get_class_name ( ) const

inlineoverridevirtual

returns the name of the class

Implements teca_algorithm.

◆ initialize_output_metadata()

teca_metadata teca_table_reduce::initialize_output_metadata	(	unsigned int	port,
		const std::vector< teca_metadata > &	input_md
	)

overrideprotectedvirtual

An override that allows derived classes to report what they can produce. this will be called from ::get_output_metadata which will strip out time and partition time across MPI ranks.

Implements teca_index_reduce.

◆ initialize_upstream_request()

std::vector<teca_metadata> teca_table_reduce::initialize_upstream_request	(	unsigned int	port,
		const std::vector< teca_metadata > &	input_md,
		const teca_metadata &	request
	)

overrideprotectedvirtual

An override that allows derived classes to generate upstream requests that will be applied over all time steps. derived classes implement this method instead of ::get_upstream_request, which here is already implemented to handle the application of requests over the index set.

Implements teca_index_reduce.

◆ New()

static p_teca_table_reduce teca_table_reduce::New ( )

inlinestatic

Returns an instance of teca_table_reduce

◆ reduce()

p_teca_dataset teca_table_reduce::reduce	(	int	device_id,
		const const_p_teca_dataset &	left,
		const const_p_teca_dataset &	right
	)

overrideprotectedvirtual

An override that implements the reduction. given two datasets a left and right, reduce into a single dataset and return.

Parameters

[in]	device_id	The device that should be used for the reduction. A value of -1 indicates the CPU should be used.
[in]	left	a dataset to reduce
[in]	right	a dataset to reduce

Returns: the reduced dataset

Implements teca_index_reduce.

◆ shared_from_this() [1/2]

std::shared_ptr< teca_table_reduce > teca_table_reduce::shared_from_this ( )

inline

Enables the static constructor

◆ shared_from_this() [2/2]

std::shared_ptr< teca_table_reduce const> teca_table_reduce::shared_from_this ( ) const

inline

Enables the static constructor
