Subject [jira] Commented: (OPENJPA-117) Collection of TransactionListeners registered to a Broker should be available as unmodifiable collection
Date Tue, 30 Jan 2007 18:37:33 GMT

Patrick Linskey commented on OPENJPA-117:
-----------------------------------------

The problem is that this lets party A get what party B set. So if one bit of code added a
particular listener, a different bit of code could then get the listener and remove it. Is
this something that we want to make easy for people to do? It seems like different listeners
should be relatively isolated from each other.

> Currently TransactionListeners can be added/removed to a broker but the list of transaction
listeners registered to a particular broker is not available. Such a collection can be made
available in read-only mode so a caller can determine whether to add a new listener or not,
or whether a particular listener is already registered.
