Class PayloadCarryingRpcController

java.lang.Object

org.apache.hadoop.hbase.ipc.TimeLimitedRpcController

org.apache.hadoop.hbase.ipc.PayloadCarryingRpcController

All Implemented Interfaces:

com.google.protobuf.RpcController, CellScannable

Direct Known Subclasses:

DelegatingPayloadCarryingRpcController

@InterfaceAudience.Private
public class PayloadCarryingRpcController
extends TimeLimitedRpcController
implements CellScannable

Optionally carries Cells across the proxy/service interface down into ipc. On its way out it optionally carries a set of result Cell data. We stick the Cells here when we want to avoid having to protobuf them. This class is used ferrying data across the proxy/protobuf service chasm. Used by client and server ipc'ing.
