◆ Group() [1/2]
This constructor creates or opens a group depending on the value of mode. The group will be placed inside the group parent_group. The parameter mpi defines if the I/O operations are serial or parallel. This is an internal constructor, the functions open_group() and create_group() of the current class should be used to open or create a group.

Internal constructor used by File. The constructor sets the protected const members of HDF5Group: name and mpi. It does not create or open a Group.

Creates a dataset. number can be float, double, std::complex<float>, std::complex<double>, int or unsigned int.
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.

template<typename Container >

Create and write data to a dataset. number can be float, double, std::complex<float>, std::complex<double>, int or unsigned int.
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.
Container can be std::vector<float>, std::vector<double>, std::vector<std::complex<float>>, std::vector<std::complex<double>>, std::vector<int>, std::vector<unsigned int>, Vector<float>, Vector<double>, Vector<std::complex<float>>, Vector<std::complex<double>>, FullMatrix<float>, FullMatrix<double>, FullMatrix<std::complex<float>> or FullMatrix<std::complex<double>>.

◆ get_attribute() [1/2]
template<typename T >
| T HDF5::HDF5Object::get_attribute |

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.

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 82 of file hdf5.cc.
◆ name
| const std::string HDF5::HDF5Object::name |
|
protectedinherited |
Name of the HDF5Oject. 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 406 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 415 of file hdf5.h.
◆ mpi
| const bool HDF5::HDF5Object::mpi |
|
protectedinherited |
If true use parallel HDF5, if false use serial HDF5.
