Detailed Description

A class for writing attributes from an HDF-EOS2 file.

This class contains functions that generates SDS attributes and Vdata attributes. Since HDF-EOS2 library API don't have access to field attributes, we need to use generic HDF4 API.

For most HDF-EOS2 files, Grid doesn't use Vdata. Swath has Vdata but fields with Vdata normally contain attributes. However, we still check and provide ways to generate attributes.

◆ close()

bool HE2CF::close ( )

closes the opened file.

Definition at line 920 of file HE2CF.cc.

◆ get_metadata()

string HE2CF::get_metadata	(	const std::string &	metadataname,
		bool &	suffix_is_num,
		std::vector< std::string > &	non_num_names,
		std::vector< std::string > &	non_num_data )

retrieves the merged metadata.

Definition at line 936 of file HE2CF.cc.

◆ open()

bool HE2CF::open	(	const std::string &	filename,
		const int	sd_id,
		const int	file_id )

openes \afilename HDF4 file.

Definition at line 943 of file HE2CF.cc.

◆ set_DAS()

void HE2CF::set_DAS ( libdap::DAS * das )

sets DAS pointer so that we can bulid attribute tables.

Definition at line 181 of file HE2CF.cc.

◆ set_non_ecsmetadata_attrs()

bool HE2CF::set_non_ecsmetadata_attrs ( )

Definition at line 186 of file HE2CF.cc.

◆ write_attribute()

bool HE2CF::write_attribute	(	const std::string &	gname,
		const std::string &	fname,
		const std::string &	newfname,
		int	n_groups,
		int	fieldtype )

writes attribute table into DAS given grid/swath name and its field name.

Definition at line 973 of file HE2CF.cc.

◆ write_attribute_coordinates()

bool HE2CF::write_attribute_coordinates	(	const std::string &	varname,
		const std::string &	coord )

writes coordinates attribute into varname attribute table.

This attribute plays an essential role for two dimensional coordinate system like Swath.

Definition at line 1134 of file HE2CF.cc.

◆ write_attribute_FillValue()

bool HE2CF::write_attribute_FillValue	(	const std::string &	varname,
		int	type,
		float	val )

writes _FillValue attribute into varname attribute table.

This attribute plays an essential role for two dimensional coordinate system like Swath.

Definition at line 1040 of file HE2CF.cc.

◆ write_attribute_units()

bool HE2CF::write_attribute_units	(	const std::string &	varname,
		const std::string &	units )

writes units attribute into varname attribute table.

Any existing units attribute will be overwritten by this function.
