Detailed Description

Wrapper for standard HDF5 operations.

Function Documentation

_get_PYTABLES_COMPLEX128()

hid_t h5wrap::_get_PYTABLES_COMPLEX128 ( )

inline

Create an HDF5 data type for complex 128 bit data, which happens to match the complex data type that is used by PyTables ^_~.

Definition at line 735 of file pyne.h.

get_array_index()

template<typename T >

template double h5wrap::get_array_index	(	hid_t	dset,
		int	n,
		hid_t	dtype = H5T_NATIVE_DOUBLE )

Retrieves the nth index out of the dataset dset (which has an HDF5 datatype dtype).

The value is returned as the C/C++ type given by T.

Definition at line 473 of file pyne.h.

h5_array_to_cpp_set()

template<typename T >

std::set< T > h5wrap::h5_array_to_cpp_set	(	hid_t	h5file,
		std::string	data_path,
		hid_t	dtype = H5T_NATIVE_DOUBLE )

Reads in data from an HDF5 file as a C++ set.

T should roughly match dtype.

Parameters

h5file	HDF5 file id for an open file.
data_path	path to the data in the open file.
dtype	HDF5 data type for the data set at data_path.

Returns

an in memory set of type T.

Definition at line 517 of file pyne.h.

h5_array_to_cpp_vector_1d()

template<typename T >

std::vector< T > h5wrap::h5_array_to_cpp_vector_1d	(	hid_t	h5file,
		std::string	data_path,
		hid_t	dtype = H5T_NATIVE_DOUBLE )

Reads in data from an HDF5 file as a 1 dimiensional vector.

T should roughly match dtype.

Parameters

h5file	HDF5 file id for an open file.
data_path	path to the data in the open file.
dtype	HDF5 data type for the data set at data_path.

Returns

an in memory 1D vector of type T.

Definition at line 548 of file pyne.h.

h5_array_to_cpp_vector_2d()

template<typename T >

std::vector< std::vector< T > > h5wrap::h5_array_to_cpp_vector_2d	(	hid_t	h5file,
		std::string	data_path,
		hid_t	dtype = H5T_NATIVE_DOUBLE )

Reads in data from an HDF5 file as a 2 dimiensional vector.

T should roughly match dtype.

Parameters

h5file	HDF5 file id for an open file.
data_path	path to the data in the open file.
dtype	HDF5 data type for the data set at data_path.

Returns

an in memory 2D vector of type T.

Definition at line 578 of file pyne.h.

h5_array_to_cpp_vector_3d()

template<typename T >

std::vector< std::vector< std::vector< T > > > h5wrap::h5_array_to_cpp_vector_3d	(	hid_t	h5file,
		std::string	data_path,
		hid_t	dtype = H5T_NATIVE_DOUBLE )

Reads in data from an HDF5 file as a 3 dimiensional vector.

T should roughly match dtype.

Parameters

h5file	HDF5 file id for an open file.
data_path	path to the data in the open file.
dtype	HDF5 data type for the data set at data_path.

Returns

an in memory 3D vector of type T.

Definition at line 613 of file pyne.h.

path_exists()

bool h5wrap::path_exists ( hid_t h5file, std::string path )

inline

Determines if a path exists in an hdf5 file.

Parameters

h5file	HDF5 file id for an open file.
path	path to the data in the open file.

Returns

true or false

Definition at line 751 of file pyne.h.
