public class RequestCollapser

extends java.lang.Object

This class is used to collapse multiple requests by simply spawning a thread the first time it receives a request, execute that request in the thread, and once the thread finishes execution it will come back to execute the next request if any. The request collapsing stems from the fact that while the thread is busy executing one request, all the newly posted ones will be ignored except for the most recent.
