Detailed Description
Data structure and retrieval processing header for the default option.
This file is part of h5_dap_handler, A C++ implementation of the DAP handler for HDF5 data.
It defines functions that describe and retrieve group/dataset from HDF5 files.
Definition in file h5dmr.h.
Function Documentation
◆ breadth_first()
| bool breadth_first | ( | const hid_t | file_id, |
| hid_t | pid, | ||
| char * | gname, | ||
| D4Group * | par_grp, | ||
| const char * | fname, | ||
| bool | use_dimscale, | ||
| vector< link_info_t > & | hdf5_hls | ||
| ) |
bool breadth_first(const hid_t file_id,hid_t pid, char gname, DMR & dmr, D4Group par_grp, const char *fname,bool use_dimscale, vector <link_info_t> & hdf5_hls)
- Parameters
-
file_id file_id(this is necessary for searching the hardlinks of a dataset) pid group id gname group name (the absolute path from the root group) dmr reference of DMR object fname the HDF5 file name use_dimscale whether dimension scales are used. hdf5_hls the vector to save all the hardlink info.
- Returns
- 0, if failed.
- 1, if succeeded.
- Remarks
- hard link is treated as a dataset.
- will return error message to the DAP interface.
- The reason to use breadth_first is that the DMR representation needs to show the dimension names and the variables under the group first and then the group names. So we use this search. In the future, we may just use the breadth_first search for all cases.??
- See also
- depth_first(hid_t pid, char *gname, DMR & dmr, const char *fname) in h5dds.cc
To keep track of soft links.
