v1.8.5
ae403b8

Highlights

  • New function h5pp::File::setKeepFileOpened() and h5pp::File::setKeepFileClosed() to keep h5pp from closing the file between operations. This can greatly improve throughput of batch operations.
  • Better handling of hyperslabs (i.e. read/write subset of datasets)
  • New examples describing hyperslab usage
  • New functions .writeHyperslab() and .readHyperslab()
  • Speed-ups from skipped logging and re-use of expensive HDF5 identifiers
  • Many changes in naming convention both internal and public-facing to be more consistent and self-explanatory
  • More efficient scanning of types, in particular when reusing metadata.
  • Faster search for datasets/groups in file
