/**
* This class provides methods to send events of types
* handled by MIDletExecuteEventConsumer I/F implementors.
* This class completely hide event construction & sending in its methods.
*
* The only user of this class in AppIsolateMIDletSuiteLoader in
* application isolate (when no midlets & no midlet suites exist).
*
* Generic comments for all XXXEventProducers:
*
* For each supported event type there is a separate sendXXXEvent() method,
* that gets all needed parameters to construct an event of an approprate class.
* The method also performs event sending itself.
*
* If a given event type merges a set of logically different subtypes,
* this class shall provide separate methods for these subtypes.
*
* It is assumed that only one object instance of this class (per isolate)
* is created at (isolate) startup.
* All MIDP stack subsystems that need to send events of supported types,
* must get a reference to an already created istance of this class.
* Typically, this instance should be passed as a constructor parameter.
*
* For security reasons constructor is not public.
* Use createXXXProducer(...) method,
* protected by security, to create and object instance of this class
* from a different package.
*
* Class is NOT final to allow debug/profile/test/automation subsystems
* to change, substitute, complement default "event sending" functionality :
* Ex.
* class LogXXXEventProducer
* extends XXXEventProducer {
* ...
* void sendXXXEvent(parameters) {
* LOG("Event of type XXX is about to be sent ...")
* super.sendXXXEvent(parameters);
* LOG("Event of type XXX has been sent successfully !")
* }
* ...
* }
