Creates or opens an HDF5 file for serial operations. This call does not require MPI support. It creates or opens an HDF5 file depending on the value of mode
.
Definition at line 390 of file hdf5.cc.
◆ File() [2/3]
Creates or opens an HDF5 file in parallel using MPI. This requires that deal.II and HDF5 were compiled with MPI support. It creates or opens a HDF5 file depending on the value of mode
. mpi_communicator
defines the processes that participate in this call; MPI_COMM_WORLD
is a common value for the MPI communicator.
Definition at line 404 of file hdf5.cc.
◆ File() [3/3]
Delegation internal constructor. File(const std::string &, const MPI_Comm , const Mode); and File(const std::string &, const Mode) should be used to open or create HDF5 files.

◆ get_attribute() [1/2]

Reads an attribute. T
can be float
, double
, std::complex<float>
, std::complex<double>
, int
, unsigned int
, bool
or std::string
. Note that the encoding of std::string
is UTF8 in order to be compatible with python3.
Datatype conversion takes place at the time of a read or write and is automatic. See the Data Transfer: Datatype Conversion and Selection section in the HDF5 User's Guide.

◆ get_name()

const |
|
inherited |
Returns the name of the object. In the case of File, name corresponds to the file name. In the case of Group and DataSet, name corresponds to the name of the object in the HDF5 file.
Definition at line 76 of file hdf5.cc.
◆ name
const std::string HDF5::HDF5Object::name |
|
protectedinherited |
Name of the HDF5Object. In the case of File, name
corresponds to the file name. In the case of Group and DataSet name
corresponds to the name of the object in the HDF5 file.
Definition at line 405 of file hdf5.h.
◆ hdf5_reference
std::shared_ptr<hid_t> HDF5::HDF5Object::hdf5_reference |
|
protectedinherited |
HDF5 identifier for the objects File, Group and DataSet. The std::shared_ptr<>
pointer allows the object to be copied. For example several parts of the program can share and access the same group; when all the functions that access the group are closed, the HDF5 resources of the group will be automatically released.
Definition at line 414 of file hdf5.h.
◆ mpi
const bool HDF5::HDF5Object::mpi |
|
protectedinherited |
If true use parallel HDF5, if false use serial HDF5.
