Package io.deephaven.server.table

Class ExportedTableUpdateListener

java.lang.Object

io.deephaven.server.table.ExportedTableUpdateListener

All Implemented Interfaces:

io.grpc.stub.StreamObserver<io.deephaven.proto.backplane.grpc.ExportNotification>

public class ExportedTableUpdateListener
extends Object
implements io.grpc.stub.StreamObserver<io.deephaven.proto.backplane.grpc.ExportNotification>

Manage the lifecycle of exports that are Tables.

Initially we receive a run of exports from the session state. This allows us to timely notify the observer of existing table sizes for both static tables and tables that won't tick frequently. When the run is complete we are sent a notification for exportId == 0 (which is otherwise an invalid export id).
