com.ibm.jbatch.container.impl
Class SingleThreadedStepControllerImpl

java.lang.Object
  com.ibm.jbatch.container.impl.BaseStepControllerImpl
      com.ibm.jbatch.container.impl.SingleThreadedStepControllerImpl

All Implemented Interfaces:

IController

Direct Known Subclasses:

BatchletStepControllerImpl, ChunkStepControllerImpl

public abstract class SingleThreadedStepControllerImpl
extends BaseStepControllerImpl
implements IController

When a partitioned step is run, this controller will only be used for the partition threads, NOT the top-level main thread that the step executes upon. When a non-partitioned step is run this controller will be used as well (and there will be no separate main thread with controller).
