seda for dummy questions: events

Hi,

Since there is more interface than there are actually extensible/pluggable implementations, I need
some clarification on where to start. But I keep the hard question for later. For the moment, as
an introduction:

1-true or false:
To receive StageInitializedSignal, one piece of code must register a sink to the signal manager.
This signal is not sent by default, only EventHandlerIF.init() is ensured. true/false?

2-How/where do I fire a signal?

3-Is the signal type detection based on the classname, class object (object.getClass()),
equals(..),  or other?

4-How do I create new signals, (if needed according to the above)(meaning: declaring their
existence so that others can be registered/denied to it)?

Thanks.
Dan.

PS: I'm no rookie in java nor in threading. You can speak technical. I'm just a bit confused by
the  API which could be somewhat more straight forward or at least documented other than javadoc.
The PDFs are not detailed enought. I'm sure a couple class and sequence diagrams would suffice.
