Detailed Description

A dataset used to read NetCDF CF2 time and metadata in parallel.

The dataset contains elements (one per file) of type: std::pair<p_teca_variant_array, teca_metadata> holding the time axis and associated NetCDF attributes.

Constructor & Destructor Documentation

◆ teca_cf_time_axis_data()

teca_cf_time_axis_data::teca_cf_time_axis_data ( )

Note: This constructor is public to enable std::make_shared. Do not use.

Member Function Documentation

◆ append()

void teca_cf_time_axis_data::append ( const const_p_teca_dataset & other )

append the data from the other instance

◆ copy()

void teca_cf_time_axis_data::copy	(	const const_p_teca_dataset &	other,
		allocator	alloc = `allocator::malloc`
	)

overridevirtual

Deep copy data and metdata.

Parameters

[in]	other	The dataset to copy.
[in]	alloc	The allocator to use for alloctions of data structures to hold the copy. The default is a CPU based allocator.

Reimplemented from teca_dataset.

◆ empty()

bool teca_cf_time_axis_data::empty ( ) const

overridevirtualnoexcept

return true if the dataset is empty.

Reimplemented from teca_dataset.

◆ get()

elem_t& teca_cf_time_axis_data::get ( unsigned long file_id )

access the file's element

◆ get_class_name()

std::string teca_cf_time_axis_data::get_class_name ( ) const

inlineoverridevirtual

return a unique string identifier

Implements teca_dataset.

◆ get_metadata() [1/2]

static const teca_metadata& teca_cf_time_axis_data::get_metadata ( const elem_t & elem )

inlinestatic

given an element extract metadata

◆ get_metadata() [2/2]

static teca_metadata& teca_cf_time_axis_data::get_metadata ( elem_t & elem )

inlinestatic

given an element extract metadata

◆ get_type_code()

int teca_cf_time_axis_data::get_type_code ( ) const

overridevirtual

return an integer identifier uniquely naming the dataset type

Implements teca_dataset.

◆ get_variant_array() [1/2]

static const_p_teca_variant_array teca_cf_time_axis_data::get_variant_array ( const elem_t & elem )

inlinestatic

given an element extract the time axis

◆ get_variant_array() [2/2]

static p_teca_variant_array teca_cf_time_axis_data::get_variant_array ( elem_t & elem )

inlinestatic

given an element extract the time axis

◆ new_copy()

virtual p_teca_dataset teca_cf_time_axis_data::new_copy ( allocator alloc = allocator::malloc ) const

inlineoverridevirtual

Implements teca_dataset.

◆ new_shallow_copy()

virtual p_teca_dataset teca_cf_time_axis_data::new_shallow_copy ( )

inlineoverridevirtual

Virtual shallow copy constructor. return a shallow copy of this dataset in a new instance. References to source data structures are taken, but metadata is always deep copied.

Implements teca_dataset.

◆ operator bool()

teca_cf_time_axis_data::operator bool ( ) const

inlineexplicitnoexcept

covert to boolean.

Returns: true if the dataset is not empty, otherwise false.

◆ shallow_copy()

void teca_cf_time_axis_data::shallow_copy ( const p_teca_dataset & other )

overridevirtual

Shallow copy data and metadata. The shallow copy takes references to the source data structures. Metadata is always deep copied.

Parameters

[in] other The dataset to copy.

Reimplemented from teca_dataset.

◆ swap()

void teca_cf_time_axis_data::swap ( const p_teca_dataset & other )

overridevirtual

swap internals of the two objects

Reimplemented from teca_dataset.

◆ to_stream() [1/2]

int teca_cf_time_axis_data::to_stream ( std::ostream & ) const

overridevirtual

stream to/from human readable representation

Reimplemented from teca_dataset.

◆ to_stream() [2/2]

int teca_cf_time_axis_data::to_stream ( teca_binary_stream & ) const

overridevirtual

serialize the dataset to/from the given stream for I/O or communication

Reimplemented from teca_dataset.

◆ transfer()

void teca_cf_time_axis_data::transfer	(	unsigned long	file_id,
		elem_t &&	data
	)

transfer the element associated with file to the dataset. after transfer the passed element is invalid in the calling context
