Class for HDF5 integer-datatypes.

Inherits from class H5T. Users should not create integer datatypes themselves using this class. Instead, integer should be derived from one of the base-types such as h5types$H5T_NATIVE_INT (which internally automatically creates a copy of the type). For a complete list of types see h5types$overview.

Value

Object of class H5T_INTEGER.

Methods

set_sign(sign)

This function implements the HDF5-API function H5Tset_sign. Please see the documentation at https://docs.hdfgroup.org/hdf5/develop/group___h5_t.html for details.

get_sign()

This function implements the HDF5-API function H5Tget_sign. Please see the documentation at https://docs.hdfgroup.org/hdf5/develop/group___h5_t.html for details.

describe()

Return a vector that describes the key features of the datatype
