Package org.apache.hadoop.yarn.csi.translator

Interface ProtoTranslator<A,B>

Type Parameters:
A - YARN side internal messages
B - CSI proto messages
All Known Implementing Classes:
GetPluginInfoResponseProtoTranslator, NodePublishVolumeRequestProtoTranslator, NodeUnpublishVolumeRequestProtoTranslator, ValidateVolumeCapabilitiesRequestProtoTranslator, ValidationVolumeCapabilitiesResponseProtoTranslator
public interface ProtoTranslator<A,B>
ProtoTranslator converts a YARN side message to CSI proto message and vice versa. Each CSI proto message should have a corresponding YARN side message implementation, and a transformer to convert them one to the other. This layer helps we to hide CSI spec messages from YARN components.
