bool check_h5str ( hid_t h5type )

checks if type is HDF5 string type

Author: Hyo-Kyung Lee hyokl.nosp@m.ee@h.nosp@m.dfgro.nosp@m.up.o.nosp@m.rg; Muqun Yang ymuqu.nosp@m.n@hd.nosp@m.fgrou.nosp@m.p.or.nosp@m.g

Parameters

h5type data type id

Returns: true if type is string; false otherwise

Definition at line 802 of file h5get.cc.

void close_fileid ( hid_t fid )

closes HDF5 file reffered by fid.

This function closes the HDF5 file.

Parameters

fid	HDF5 file id

Returns: throws an error if it can't close the file.

string get_dap_type ( hid_t type )

returns the string representation of HDF5 type.

This function will get the text representation(string) of the corresponding DODS datatype. DODS-HDF5 subclass method will use this function.

Returns: string

Parameters

type	datatype id

void get_data	(	hid_t	dset,
		void *	buf
	)

will get all data of a dset dataset and put it into buf.

Parameters

[in]	dset	dataset id(dset)
[out]	buf	pointer to a buffer

void get_dataset	(	hid_t	pid,
		const string &	dname,
		DS_t *	dt_inst_ptr
	)

obtain data information in a dataset datatype, dataspace(dimension sizes) and number of dimensions and put these information into a pointer of data struct.

Parameters

[in]	pid	parent object id(group id)
[in]	dname	dataset name
[out]	dt_inst_ptr	pointer to the attribute struct(* attr_inst_ptr)

Definition at line 374 of file h5get.cc.

hid_t get_fileid ( const char * filename )

gets HDF5 file id.

This function is used because H5Fopen cannot be directly used in a C++ code.

Parameters

filename HDF5 filename

Returns: a file handler id

Definition at line 334 of file h5get.cc.

Referenced by HDF5RequestHandler::hdf5_build_das(), HDF5RequestHandler::hdf5_build_data(), and HDF5RequestHandler::hdf5_build_dds().

int get_slabdata	(	hid_t	dset,
		int *	offset,
		int *	step,
		int *	count,
		int	num_dim,
		void *	buf
	)

will get hyperslab data of a dataset and put it into buf.

Parameters

[in]	dset	dataset id
[in]	offset	starting point
[in]	step	stride
[in]	count	count
[in]	num_dim	number of array dimensions
[out]	buf	pointer to a buffer

Definition at line 661 of file h5get.cc.

void get_strdata	(	int	strindex,
		char *	allbuf,
		char *	buf,
		int	elesize
	)

will get an individual string data from all string data elements and put it into buf.

Parameters

[in]	strindex	index of H5T_STRING array
[in]	allbuf	pointer to string buffer that has been built so far
[in]	elesize	size of string element in the array
[out]	buf	pointer to a buf

Returns: void
