question: public void invokeHookBoltExecute ( Tuple tuple , long executeLatencyNs ) { if ( taskHooks . size ( ) != 0 ) { BoltExecuteInfo executeInfo = new BoltExecuteInfo ( tuple , getThisTaskId ( ) , executeLatencyNs / Constants . MILLISECONDS_TO_NANOSECONDS ) ; for ( ITaskHook taskHook : taskHooks ) { taskHook . boltExecute ( executeInfo ) ; } } }
target:  Task hook called in bolt every time a tuple gets executed
