Method Detail

createFile

public void createFile(MFCCardChannel channel,
                       byte[] header)
                throws CardServiceException,
                       CardTerminalException
Creates a file on the smartcard. The directory in which the file should be created has to be selected. The file itself may be an elementary or dedicated file. All information required to create the file is encoded in that header. The encoding is card-specific.
Parameters:
channel - the contact to the smartcard
header - the header of the file to create
Throws:
CardServiceException - if the service encountered an error
CardTerminalException - if the terminal encountered an error

deleteFile

public void deleteFile(MFCCardChannel channel,
                       short file)
                throws CardServiceException,
                       CardTerminalException
Deletes a file on the smartcard. The parent directory of the file to delete has to be selected. The file itself may be an elementary or dedicated file. The smartcard's restrictions for deleting files apply.
Parameters:
channel - the contact to the smartcard
file - the identifier of the file to delete
Throws:
CardServiceException - if the service encountered an error
CardTerminalException - if the terminal encountered an error

invalidateFile

public void invalidateFile(MFCCardChannel channel)
                    throws CardServiceException,
                           CardTerminalException
Invalidates a file on the smartcard. The file to be invalidated has to be selected. The file itself may be a dedicated or elementary file.
Parameters:
channel - the contact to the smartcard
Throws:
CardServiceException - if the service encountered an error
CardTerminalException - if the terminal encountered an error

rehabilitateFile

public void rehabilitateFile(MFCCardChannel channel)
                      throws CardServiceException,
                             CardTerminalException
Rehabilitates a file on the smartcard. The file to be rehabilitated has to be selected. The file itself may be a dedicated or elementary file.
Parameters:
channel - the contact to the smartcard
Throws:
CardServiceException - if the service encountered an error
CardTerminalException - if the terminal encountered an error
