Class SingleConnection<StreamRequestT,StreamResponseT,ClientResponseT>

java.lang.Object

com.google.cloud.pubsublite.internal.wire.SingleConnection<StreamRequestT,StreamResponseT,ClientResponseT>

Type Parameters:

StreamRequestT - The request type sent on the stream.

StreamResponseT - The response type sent from the stream.

ClientResponseT - The response type sent to the client.

All Implemented Interfaces:

io.grpc.stub.StreamObserver<StreamResponseT>, AutoCloseable

Direct Known Subclasses:

ConnectedAssignerImpl, ConnectedCommitterImpl

public abstract class SingleConnection<StreamRequestT,StreamResponseT,ClientResponseT>
extends Object
implements io.grpc.stub.StreamObserver<StreamResponseT>, AutoCloseable

A SingleConnection handles the state for a stream with an initial connection request that may only be sent once and needs to wait for a response before sending other requests.
