Member Function Documentation

add_missing_cf_attrs()

void HDFCFUtil::add_missing_cf_attrs ( const HDFSP::File * f, libdap::DAS & das )

static

Definition at line 2099 of file HDFCFUtil.cc.

add_obpg_special_attrs()

void HDFCFUtil::add_obpg_special_attrs ( const HDFSP::File * f, libdap::DAS & das, const HDFSP::SDField * spsds, const std::string & scaling, float & slope, const bool & global_slope_flag, float & intercept, const bool & global_intercept_flag )

static

Definition at line 1867 of file HDFCFUtil.cc.

check_obpg_global_attrs()

void HDFCFUtil::check_obpg_global_attrs ( HDFSP::File * f, std::string & scaling, float & slope, bool & global_slope_flag, float & intercept, bool & global_intercept_flag )

static

Definition at line 1791 of file HDFCFUtil.cc.

close_fileid()

void HDFCFUtil::close_fileid ( int32 sdfd, int32 file_id, int32 gridfd, int32 swathfd, bool pass_fileid_key )

static

Close HDF4 and HDF-EOS2 file IDs. For performance reasons, we want to keep HDF-EOS2/HDF4 IDs open for one operation(DDS,DAS or DATA). In case of exceptions, these IDs need to be closed.

Definition at line 3559 of file HDFCFUtil.cc.

correct_fvalue_type()

void HDFCFUtil::correct_fvalue_type ( libdap::AttrTable * at, int32 dtype )

static

CF requires the _FillValue attribute datatype is the same as the corresponding field datatype. For some NASA files, this is not true. So we need to check if the _FillValue's datatype is the same as the attribute's. If not, we need to correct them.

Definition at line 477 of file HDFCFUtil.cc.

correct_scale_offset_type()

void HDFCFUtil::correct_scale_offset_type ( libdap::AttrTable * at )

static

CF requires the scale_factor and add_offset attribute datatypes hold the same datatype. So far we haven't found that scale_factor and add_offset attributes hold different datatypes in NASA files. But just in case, we implement a BES key to give users a chance to check this. By default, the key is always off.
