HighFive - HDF5 header-only C++ Library

HighFive is a modern C++/C++11 friendly interface for libhdf5.

HighFive supports STL vector/string, Boost::UBLAS and Boost::Multi-array. It handles C++ from/to HDF5 automatic type mapping. HighFive does not require an additional library and supports both HDF5 thread safety and Parallel HDF5 (contrary to the official hdf5 cpp)

• Simple C++-ish minimalist interface
• No other dependency than libhdf5
• Zero overhead
• Support C++11 ( compatible with C++98 )

• libhdf5
• (optional) boost >= 1.41

    using namespace HighFive;
    // we create a new hdf5 file
    File file("/tmp/new_hdf5_file.h5", File::ReadWrite | File::Create | File::Truncate);

    std::vector<int> data(50, 1);

    // lets create a dataset of native interger with the size of the vector 'data'
    DataSet dataset = file.createDataSet<int>("/dataset_one",  DataSpace::From(data));

    // lets write our vector of int to the HDF5 dataset
    dataset.write(data);
 
    // read back
    std::vector<int> result
    dataset.read(result);

mkdir build; pushd build
cmake ../
make
make test

- create/read/write file,  dataset, group, dataspace.
- automatic memory management / ref counting
- automatic convertion of  std::vector and nested std::vector from/to any dataset with basic types
- automatic convertion of std::string to/from variable length string dataset
- selection() / slice support
- parallel Read/Write operations from several nodes with Parallel HDF5
- support HDF5 attributes
