const std::string &  data_name,
InputIterIter  first,
SInputIter  sfirst,
bool  append = false 
)
inline

Store a list in the HDF5 format from an iterator to iterators.

Template Parameters
TType of the data
InputIterIterThe input iterator type, which points to input iterators
SInputIterThe input iterator type of names
Parameters
nrowNumber of elements in each element of the list
ncolNumber of elements in the list
file_nameName of the HDF5 file
data_nameName of the list
firstAn iterator points to a sequence of iterators of length ncol. Each derefence of an iterator is iteself an iterator that points to the beginning of an element of the list.
sfirstAn iterator points to the beginning of a sequence of strings that store the names of each column. The dereference need to be convertible to std::string
appendIf true the data is appended into an existing file, otherwise save in a new file
Note
Each element in the list is assumed to be a vector of the same length. If the list contains elements of different length, then create an empty list, which is exactly an empty group in HDF5 terminology and use hdf5store_list_insert to insert each element.

Definition at line 457 of file hdf5io.hpp.

template<typename SInputIter , typename InputIter , typename... InputIters>
void vsmc::hdf5store_list ( std::size_t  nrow,
const std::string &  file_name,
const std::string &  data_name,
const std::tuple< InputIter, InputIters... > &  first,
SInputIter  sfirst,
bool  append = false 
)
inline

Store a list in the HDF5 format from tuple of iterators.

A list is similar to that in R. It is much like a matrix except that each column will be stored seperatedly as an variable and given a name.

Parameters
nrowNumber of rows
file_nameName of the HDF5 file
data_nameName of the list
firstA std::tuple type object whose element types are iterators. Each element is the beginning of an element of the list.
sfirstAn iterator points to the beginning of a sequence of strings that store the names of each column. The dereference need to be convertible to std::string
appendIf true the data is appended into an existing file, otherwise save in a new file

Definition at line 587 of file hdf5io.hpp.

void vsmc::hdf5store_list_empty ( const std::string &  file_name,
const std::string &  data_name,
bool  append = false 
)
inline

Create an empty list.

Parameters
file_nameName of the HDF5 file
data_nameName of the list
appendIf true the data is appended into an existing file, otherwise save in a new file

Definition at line 411 of file hdf5io.hpp.

template<typename T , typename InputIter >
void vsmc::hdf5store_list_insert ( std::size_t  N,
const std::string &  file_name,
const std::string &  data_name,
InputIter  first,
const std::string &  vname 
)
inline

Insert a variable into an existing list saved in HDF5 format.

Parameters
NThe length of the variable vector. It may be different from that of the existing list.
file_nameName of the HDF5 file
data_nameName of the list
firstAn iterator points to the beginning of the variable vector
vnameName of the new variable

Definition at line 505 of file hdf5io.hpp.

template<MatrixLayout Layout, typename T , typename InputIter >
InputIter vsmc::hdf5store_matrix ( std::size_t  nrow,
std::size_t  ncol,
const std::string &  file_name,
const std::string &  data_name,
InputIter  first,
bool  append = false 
)
inline

Store a matrix in the HDF5 format from an input iterator.

Template Parameters
LayoutStorage layout (RowMajor or ColMajor)
TType of the data
Parameters
nrowNumber of rows
ncolNumber of columns
file_nameName of the HDF5 file
data_nameName of the matrix data
firstAn input iterator to sequence of length nrow * ncol
appendIf true the data is appended into an existing file, otherwise save in a new file
Note
HDF5 store data in row major layout. For example,
double data[6] = {1, 2, 3, 4, 5, 6};
// Store matrix
// 1 2
// 3 4
// 5 6
hdf5store_matrix<RowMajor, double>(3, 2, "row.hdf5", "data", data);
// Store matrix
// 1 4
// 2 5
// 3 6
hdf5store_matrix<ColMajor, double>(3, 2, "col.hdf5", "data", data);
When the results are read by other program, for example R, a transpose may be needed. For instance,
1 library(rhdf5)
2 row <- h5read("row.hdf5", "/data")
3 print(row) # produce
4 # [,1] [,2] [,3]
5 # [1,] 1 3 5
6 # [2,] 2 4 6
7 col <- h5read("col.hdf5", "/data")
8 print(col) # produce
9 # [,1] [,2]
10 # [1,] 1 4
11 # [2,] 2 5
12 # [3,] 3 6
13 #
That is, when the data is stored in column major layout in C++ memory, then the read in R produces exactly the same output. If the data is stored as row major matrix in C++ memory, the read in R produces the transpose the original matrix though they are identical in memory.

Definition at line 368 of file hdf5io.hpp.

void vsmc::hdf5store_new ( const std::string &  file_name)
inline

Create a new HDF5 file for store data.
