"""Representation of the ISO7816-4 filesystem model.
|
|
|
|
|
|
|
|
The File (and its derived classes) represent the structure / hierarchy
|
|
|
|
of the ISO7816-4 smart card file system with the MF, DF, EF and ADF
|
|
|
|
entries, further sub-divided into the EF sub-types Transparent, Linear Fixed, etc.
|
|
|
|
|
|
|
|
The classes are intended to represent the *specification* of the filesystem,
|
|
|
|
not the actual contents / runtime state of interacting with a given smart card.
