ml.shifu.guagua.worker
类 WorkerComputableTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object
  ml.shifu.guagua.worker.BasicWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>
      ml.shifu.guagua.worker.WorkerComputableTimer<MASTER_RESULT,WORKER_RESULT>

类型参数：

MASTER_RESULT - master result for computation in each iteration.

WORKER_RESULT - worker result for computation in each iteration.

所有已实现的接口：

WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

public class WorkerComputableTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends BasicWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

WorkerComputableTimer is used to print execution time for master computation function. Waiting time is not included in this timer.

WorkerComputableTimer should be set as user interceptor, not system interceptor.
