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.
