Class GcWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object

ml.shifu.guagua.worker.GcWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

Type Parameters:

MASTER_RESULT - master computation result in each iteration.

WORKER_RESULT - worker computation result in each iteration.

All Implemented Interfaces:

WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

public class GcWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends Object
implements WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

GcWorkerInterceptor is used to log gc time of preXXXX of interceptors, worker computation and postXXXX of interceptors. GcWorkerInterceptor should be set as system interceptor.

GcWorkerInterceptor is set as one worker interceptor by default.
