Class UICCSystem

  • public class UICCSystem
extends java.lang.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.

      • getTheUICCView

        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 java.lang.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:
        java.lang.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 java.lang.NullPointerException,
                                      java.lang.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:
        java.lang.NullPointerException - if buffer is null
        java.lang.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.
