Class UICCSystem

java.lang.Object
uicc.access.UICCSystem
public class UICCSystem extends Object
The UICCSystem class provides a way to get a view of an UICC File system. The FileView objects returned by the methods of this class are permanent JCRE Entry Point Objects.

      public static FileView getTheUICCView(byte event) throws javacard.framework.SystemException
      Method to get a reference to a FileView object on the UICC file system The FileView object will only allow access to the files specified under the MF of the UICC. It is not possible to get access to files which are located under any ADF with this FileView object. After a succesful invocation of the method the MF is the current selected file. This method return null if the Applet.register() has not yet been invoked or the filesystem server returns null
      Parameters:
      event - defining the transient type of the file context associated with the FileView object the following values are allowed JCSystem.NOT_A_TRANSIENT_OBJECT JCSystem.CLEAR_ON_RESET JCSystem.CLEAR_ON_DESELECT
      Returns:
      a reference to a class which implements the FileView interface
      Throws:
      javacard.framework.SystemException - with the following reason codes:
      • SystemException.ILLEGAL_VALUE if event is not a valid event code.
      • SystemException.NO_TRANSIENT_SPACE if sufficient transient space is not available.
      • SystemException.ILLEGAL_TRANSIENT if the current applet context is not the currently selected applet context and CLEAR_ON_DESELECT is specified.

    • getTheFileView

      public static FileView getTheFileView(javacard.framework.AID aid, byte event) throws NullPointerException, javacard.framework.SystemException
      Method to get a reference to a FileView object on an ADF file system. The FileView object will only allow access to Files under the ADF specified by the AID. It is not possible to access files which are not located under the ADF. After a succesful invocation of the method the ADF is the currently selected file. This method return null if the Applet.register() has not yet been invoked, or the filesystem server does not exist or the filesystem server returns null
      Parameters:
      event - defining the transient type of the file context associated with the FileView object the following values are allowed JCSystem.NOT_A_TRANSIENT_OBJECT JCSystem.CLEAR_ON_RESET JCSystem.CLEAR_ON_DESELECT
      aid - AID of the requested ADF
      Returns:
      a reference to a class which implements the FileView interface
      Throws:
      NullPointerException - if buffer is null
      javacard.framework.SystemException - with the following reason codes:
      • SystemException.ILLEGAL_VALUE if event is not a valid event code.
      • SystemException.NO_TRANSIENT_SPACE if sufficient transient space is not available.
      • SystemException.ILLEGAL_TRANSIENT if the current applet context is not the currently selected applet context and CLEAR_ON_DESELECT is specified.

    • getTheFileView

      public static FileView getTheFileView(byte[] buffer, short bOffset, byte bLength, byte event) throws NullPointerException, ArrayIndexOutOfBoundsException, javacard.framework.SystemException
      Method to get a reference to a FileView object on an ADF file system.
      The FileView object will only allow access to Files under the ADF specified by the AID. It is not possible to access files which are not located under the ADF. After a succesful invocation of the method the ADF is the currently selected file.
      This method return null if the Applet.register() has not yet been invoked, or the filesystem server does not exist or the filesystem server returns null

      Notes:

      • If bOffset or bLength is negative an ArrayIndexOutOfBoundsException exception is thrown.
      • If bOffset+bLength is greater than buffer.length, the length of the buffer array an ArrayIndexOutOfBoundsException exception is thrown.
      Parameters:
      buffer - array holding the AID
      bOffset - offset into the buffer indicating the start of the AID
      bLength - length into the buffer of the AID
      event - defining the transient type of the file context associated with the FileView object the following values are allowed JCSystem.NOT_A_TRANSIENT_OBJECT JCSystem.CLEAR_ON_RESET JCSystem.CLEAR_ON_DESELEC
      Returns:
      a reference to an object which implements the FileView interface, or null.
      Throws:
      NullPointerException - if buffer is null
      ArrayIndexOutOfBoundsException - in case of access outside array bounds
      javacard.framework.SystemException - with the following reason codes:
      • SystemException.ILLEGAL_VALUE if event is not a valid event code or bLength is not in the range of 5 - 16 bytes.
      • SystemException.NO_TRANSIENT_SPACE if sufficient transient space is not available.
      • SystemException.ILLEGAL_TRANSIENT if the current applet context is not the currently selected applet context and CLEAR_ON_DESELECT is specified.
