Detailed Description

Allows to receive information about the status of an OutSlot.

You can implement this interface by your own classes and add instances of these classes to OutSlots by using the addListener method. In this case, the OutSlot calls methods of this interface when special events occur. These events are:

The first InSlot connects to the OutSlot.
The last InSlot disconnects from the OutSlot.

Please keep in mind that you should not block under any circumstance in the methods, and you should not perform time-consuming tasks. These methods are just meant to do short notifications about the events.
