Defined in filesystem.js

Field Detail

globalAuthenticationState

Object globalAuthenticationState

mf

Object mf

se

Object se

FileSelector

FileSelector(<DF> mf)

Create a file selector object

Parameters:
mf - the master file

addAuthenticationState

void addAuthenticationState(<boolean> global, <AuthenticationObject> ao)

Add authenticated object to the list of authentication states for the local DF or global MF

Parameters:
global - true if global state else local DF state
ao - the authentication object for which authentication was successfull

enumerateObjects

{Number[]} enumerateObjects(<String> type)

Enumerate objects of a defined type

Parameters:
type - the type of the object

Returns:
the list of objects found

getCurrentEF

EF getCurrentEF()

Returns the current EF, if any

Returns:
the current EF or null

getMeta

Object getMeta(<String> name)

Return meta data associated with the current DF or MF

Parameters:
name - the meta data name

Returns:
The meta data

getObject

{Object} getObject(<String> type, <Number> id)

Return object of given type identified by id

If bit b8 in the id is 1, then the search will start in the current DF. If the object is not found, the search is continued in the MF. If the bit is not set, then the search will only look into the MF.

Parameters:
type - the type of the object
id - the id, bit b8 indicating local DF or global MF search

Returns:
the object of the requested type or null if not found

getSecurityEnvironment

Object getSecurityEnvironment()

Return the current security environment

Returns:
Object with properties VEXK, CDIK, SMRES and SMCOM containing SecurityEnvironment objects

isAuthenticated

Object isAuthenticated(<boolean> global, <AuthenticationObject> ao)

Add authenticated object to the list of authentication states for the local DF or global MF

Parameters:
global - true if global state else local DF state
ao - the authentication object for which authentication was successfull
