Data Stream 接口
An system.fabric.OperationDataStream encapsulates a stream of OperationData objects that are exchanged between Primary replica and Secondary replica. Objects that implement system.fabric.OperationDataStream are used during the copy process. Both the copy context getCopyContext() method that is sent from the Secondary replica to the Primary replica and the copy state getCopyState(SequenceNumber upToSequenceNumber, OperationDataStream copyContext) method implement the system.fabric.OperationDataStream interface.
public interface OperationDataStream
Gets the next OperationData object from the system.fabric.OperationDataStream.
