waitForEvent

public void waitForEvent()
                  throws Exception

Throws:

Exception

waitForFirstCheck

public void waitForFirstCheck()
                       throws Exception

we don't reset the signal so if there was a check it is already true and exit immediatly otherwise it will behave just like waitForCheck()

Throws:

Exception - in case of a timeout

public void waitForCheck()
                  throws Exception

wait for the next filesystem check to happen
