Interface ToolkitRegistry

  • public interface ToolkitRegistry
    The ToolkitRegistry interface offers basic services and methods to allow any Toolkit Applet to register its configuration (supported events) during the install phase and possibly to change it during all the applet life time. Each Toolkit Applet will get a reference to its registry entry with the static method getEntry from the ToolkitRegistrySystem class The initial state of all the events is cleared. The registry entry object implementing the ToolkitRegistry interface is a permanent JCRE entry point object

    All updates performed on the ToolkitRegistry are atomic. The ToolkitRegistry update operations are subject to atomic commit capacity limitations. If the commit capacity is exceeded, no update is performed and a TransactionException exception is thrown.

    Note: the constants related to the events are defined in the ToolkitConstants interface.

                   javacard.framework.TransactionException
        Asks the CAT Runtime Environment to allocate a Timer that the applet can manage. By calling this method the applet is registered to the EVENT_TIMER_EXPIRATION of the allocated timer. The timer is allocated by the applet until it explicitly releases it. So it can then issue the Timer Management proactive command to start, stop or get the value of its allocated timer.
        Returns:
        the identifier of the Timer allocated to the applet
        Throws:
        ToolkitException - with the following reason codes:
        • NO_TIMER_AVAILABLE if all the timers are allocated or the maximum number of timers have been allocated to this applet
        javacard.framework.TransactionException - if the operation would cause the commit capacity to be exceeded

        void releaseTimer​(byte timerIdentifier)
           throws ToolkitException,
                  javacard.framework.TransactionException
        Release a Timer that has been allocated to the calling applet. The applet is deregistered of the EVENT_TIMER_EXPIRATION for the indicated Timer Identifier.
        Parameters:
        timerIdentifier - the identifier of the Timer to be released
        Throws:
        ToolkitException - with the following reason codes:

                  throws ToolkitException,
                         javacard.framework.TransactionException
        Requests a duration for the EVENT_STATUS_COMMAND event of the registering Toolkit Applet. Due to different duration requested by other Toolkit Applets or due to restriction of the Terminal, the CAT Runtime Environment may adjust another duration. This method can be used at every time to request a new duration.
        Parameters:
        duration - specifies the number of seconds requested for proactive polling. The maximum value of duration is 15300 (255 minutes). If duration is equal to POLL_NO_DURATION, the calling applet deregisters from EVENT_STATUS_COMMAND, and the CAT Runtime Environment shall issue a POLLING_OFF proactive command when no more ToolkitApplets are regustered for this event or it shall issue POLL_INTERVALL proactive command using the shortest duration among those requested by Applets registered to this event if different from the current system poll interval value. If duration is equal to POLL_SYSTEM_DURATION, the calling applet registers to the EVENT_STATUS_COMMAND and let the CAT Runtime Environment define the duration. If the method is invoked during the processing of the event EVENT_POLL_INTERVAL_NEGOTIATION and if the requested value is longer than the one suggested by the Terminal, then the requested value shall be ignored.
        Throws:
        ToolkitException - with the following reason codes:
        • REGISTRY_ERROR if duration is greater than the maximum value.
        javacard.framework.TransactionException - if the operation would cause the commit capacity to be exceeded

      • getPollInterval

        short getPollInterval()
        Returns the number of seconds of the adjusted duration for the calling Toolkit Applet. If the returned duration is equal to POLL_NO_DURATION, the Toolkit Applet is not registered to EVENT_STATUS_COMMAND event. The returned duration may :
        • be a multiple of the real adjusted poll interval time at the Terminal.
        • differ from the requested duration due to request of other toolkit applets or due to restrictions of the current Terminal.
        • be the poll interval duration that was determined with the POLL INTERVAL NEGOTIATION mechanism
        • be changed during the card session due requests from other Toolkit Applets
        • not correspond to the elapsed time due to additional STATUS commands send by the Terminal.
        Returns:
        the number of seconds of the adjusted duration for the applet

        Deregister a ToolkitRegistry object from the EVENT_EXTERNAL_FILE_UPDATE for a file.
        Parameters:
        fileEvent - Indicates the File event to be deregistered
        aFileView - The FileView object's current file indicates the file that is no longer monitored. If the current file is a dedicated file the deregistration shall not affect the monitoring of an elementary file within the dedicated file that was individually registered. If the current file is an elementary file the deregistration will not affect the monitoring of the parent dedicated file that was individually registered.
        Throws:
        java.lang.NullPointerException - if aFileView is null
        javacard.framework.TransactionException - if the operation would cause the commit capacity to be exceeded
