/** Internal class LCount is used to track the number of
|
|
listeners registered for a given event name, as an entry
|
|
in a global Map. This should allow us to avoid generating,
|
|
or discarding, events for which no listeners are registered.
|
|
|
|
***** There should undoubtedly be methods here to manipulate
|
|
this table. At the moment that code's residing in NodeImpl.
|
|
Move it when we have a chance to do so. Sorry; we were
|
|
rushed.
