You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Hdf5ElementStrainBar.m
    path of file: ./repos/NASTRAN_CoFE/nastran_cofe/hdf5_output_processors
    
    the code of the file until where you have to start completion: %Hdf5ElementStrainBar HDF5 data class for BAR element strain data.
