Interface to HDF5 files. More...

#include <HDF5File.h>

Public Member Functions
	HDF5File (MPI_Comm comm, const std::string &filename, const std::string &file_mode)
	Constructor. file_mode should be "a" (append), "w" (write) or "r" (read).
	~HDF5File ()
	Destructor.
void	close ()
	Close file.
void	flush ()
	Flush buffered I/O to disk.
bool	has_dataset (const std::string &dataset_name) const
	Check if dataset exists in HDF5 file.
void	set_mpi_atomicity (bool atomic)
	Set the MPI atomicity.
bool	get_mpi_atomicity () const
	Get the MPI atomicity.
hid_t	h5_id () const
	Get the file ID.
template<typename T >
void	write_data (const std::string &dataset_name, const std::vector< T > &data, const std::vector< std::int64_t > &global_size, bool use_mpi_io)
	Write contiguous data to HDF5 data set. Data is flattened into a 1D array, e.g. [x0, y0, z0, x1, y1, z1] for a vector in 3D.
template<typename T >
void	write_data (const std::string &dataset_name, const Eigen::Array< T, Eigen::Dynamic, Eigen::Dynamic, Eigen::RowMajor > &data, bool use_mpi_io)
	Write 2D dataset to HDF5. Eigen::Arrays on each process must have the same number of columns.

Public Attributes
bool	chunking = false
	Chunking parameter - partition data into fixed size blocks for efficiency.
