/**
*
* The <code>ToolkitRegistry</code> class 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 <code>getEntry</code>. The initial state of all the events
* is cleared.<p>
*
* Note: the constants related to the events are defined in the
* <code>ToolkitConstants </code> interface.<p>
*
* Example of use:<pre><code>
* public class MyToolkitApplet extends Applet implements
* ToolkitInterface, ToolkitConstants {
* // data fields
* private ToolkitRegistry reg;
* private byte[] menuEntry = { ... };
* private byte menuId;
* //
* // Constructor of applet
* //
* public MyToolkitApplet() {
* // get the reference of the applet ToolkitRegistry object ...
* reg = ToolkitRegistry.getEntry();
* // ...and initialize it according to the applet characteristics
* menuId = reg.initMenuEntry(menuEntry, (short)0,
* (short)menuEntry.length,
* PRO_CMD_SET_UP_CALL, false, 0, 0);
* reg.disableMenuEntry(menuId);
* reg.setEvent(EVENT_FORMATTED_SMS_PP_ENV);
* reg.setEvent(EVENT_CALL_CONTROL_BY_SIM);
* }
* //
* // Install method
* // *param bArray the array containing installation parameters
* // *param bOffset the starting offset in bArray
* // *param bLength the length in bytes of the parameter data in bArray
* //
* public static void install(byte bArray[], short bOffset, byte bLength)
* throws ISOException {
* // create and register applet
* MyToolkitApplet applet = new MyToolkitApplet();
* applet.register();
* }
* //
* // Process toolkit events
* // *param event the type of event to be processed
* // *exception ToolkitException
* //
* public void processToolkit(byte event) throws ToolkitException {
* if (event == EVENT_FORMATTED_SMS_PP_ENV) {
* reg.enableMenuEntry(menuId);
* } else if (event == EVENT_MENU_SELECTION) {
* //...
* }
* }
* }
