ConnectionPoolEventListener (OpenAM Server Only 7.3.3 Documentation)

All Superinterfaces:

EventListener
```
public interface ConnectionPoolEventListener
extends EventListener
```
An object that registers to be notified when a connection pool grows or shrinks.
NOTE 1: Since listeners are prone to race conditions they should only be used for monitoring and alerts. Specifically, an application should not use this mechanism to deduce whether a request can be sent or not. It should send the request and hope for the best.
NOTE 2: connection pool implementations must ensure that only one event is sent at a time. Event listener implementations should not need to be thread safe unless there are (re-)used by multiple connection pools.
