83 * \brief DICOM elements and their corresponding values (and
84 * additionaly the corresponding DICOM dictionary entry) of the header
87 * The typical usage of instances of class File is to classify a set of
88 * dicom files according to header information e.g. to create a file hierarchy
89 * reflecting the Patient/Study/Serie informations, or extracting a given
90 * SerieId. Accessing the content (image[s] or volume[s]) is beyond the
91 * functionality of this class and belongs to gdcm::FileHelper.
92 * \note The various entries of the explicit value representation (VR) shall
93 * be managed within a dictionary which is shared by all File
95 * \note The File::Set*Tag* family members cannot be defined as
96 * protected due to Swig limitations for as Has_a dependency between
97 * File and FileHelper.
