类 MasterTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object
  ml.shifu.guagua.master.MasterTimer<MASTER_RESULT,WORKER_RESULT>

类型参数：

MASTER_RESULT - master computation result in each iteration.

WORKER_RESULT - worker computation result in each iteration.

所有已实现的接口：

MasterInterceptor<MASTER_RESULT,WORKER_RESULT>

public class MasterTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends Object
implements MasterInterceptor<MASTER_RESULT,WORKER_RESULT>

MasterTimer is used to log execution time of preXXXX of interceptors, master computation and postXXXX of interceptors. MasterTimer includes waiting time and should be set as system interceptor.

MasterTimer is set as one master interceptor by default.
