Determining Capture to Dequeue Latency for all the Events

Question

Is there a way to determine the capture to dequeue latency for all the events. I was able to
determine the capture and propagation latency for the last captured event dequeued by an apply process. Is there any way to capture all the events from first till last
the query which i used to get that was
SELECT (DEQUEUE_TIME-DEQUEUED_MESSAGE_CREATE_TIME)*86400 LATENCY,
TO_CHAR(DEQUEUED_MESSAGE_CREATE_TIME,'HH24:MI:SS MM/DD/YY') CREATION,
TO_CHAR(DEQUEUE_TIME,'HH24:MI:SS MM/DD/YY') LAST_DEQUEUE,
DEQUEUED_MESSAGE_NUMBER
FROM V$STREAMS_APPLY_READER
WHERE APPLY_NAME = 'APPLY_SITE1';

Answer 1

You can simply write a unique class as an ActionListener and in its actionPerformed method you do the following:
Object source = e.getSource(); // e is our event
if (source == component1) {
} else if (source == component2) {
