question: private boolean incrementAndCheckCount ( AtomicInteger initialCount , int requestLimit ) { int count = initialCount . incrementAndGet ( ) ; if ( count > requestLimit && requestLimit != DISABLED_RATE ) { initialCount . decrementAndGet ( ) ; LOG . info ( "reject: {} > {}" , count , requestLimit ) ; return false ; } return true ; }
target:  Increment the initial count and check if the count has gone over the request limit.
