Question : Thread to monitor a queue, remove identical events like AWT does with multiple repaint requests

HI,
I am tyring to implement a worker thread that will monitor a queue and remove identical events thus leaving
only one event in the queue - eg say if there are multiple requests to turn on and off a switch in
a short period of time i only to process the last one.
I know the AWT thread in the JVM does this with multiple repaint requests in a short period of time
but i cannot find the algorithm anywhere.
At the moment i have a concurrentlinked queue that is served by a SAX parser object that parses
xml strings and creates corresponding events, there are many threads that insert events into
the queue, i have one consumer thread removing these events and putting them into a rule engine
but to save extra work i want to be able to remove multiple events of the same type.
Any ideas are most welcome.
James.

If you're trying to have at most one event of each type in the queue at any one time, you could use a LinkedHashSet - then it'd all happen automcatically
