| ForegroundEventProducer | | public class ForegroundEventProducer (Code) | | This class provides methods to send events of types
handled by ForegroundEventConsumer I/F implementors.
This class completely hide event construction & sending in its methods.
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
is initialized with the system event that is created at (isolate) startup.
This class only operates on the event queue given to it during
construction, the class does not obtain any restricted object itself,
so it does not need protection.
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.
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 !")
}
...
}
