Method Detail

sendDiscoveryRequest

void sendDiscoveryRequest(XdsResourceType<?> type,
                          java.lang.String versionInfo,
                          java.util.Collection<java.lang.String> resources,
                          java.lang.String nonce,
                          @Nullable
                          java.lang.String errorDetail)

Sends a discovery request with the given versionInfo, nonce and errorDetail. Used for reacting to a specific discovery response. For client-initiated discovery requests, use sendDiscoveryRequest(XdsResourceType, Collection).

sendDiscoveryRequest

final void sendDiscoveryRequest(XdsResourceType<?> type,
                                java.util.Collection<java.lang.String> resources)

Sends a client-initiated discovery request.

onReady

public void onReady()

Description copied from interface: XdsTransportFactory.EventHandler

Called when the stream is ready to send additional messages. If called the library use this handler to trigger resource arrival timeout, also see XdsTransportFactory.StreamingCall.isReady(). Application is free to ignore it.

Specified by:

onReady in interface XdsTransportFactory.EventHandler<DiscoveryResponse>

onRecvMessage

public void onRecvMessage(DiscoveryResponse response)

Description copied from interface: XdsTransportFactory.EventHandler

Called when a message is received on the stream.

Specified by:

onRecvMessage in interface XdsTransportFactory.EventHandler<DiscoveryResponse>

onStatusReceived

public void onStatusReceived(io.grpc.Status status)

Description copied from interface: XdsTransportFactory.EventHandler

Called when status is received on the stream.

Specified by:

onStatusReceived in interface XdsTransportFactory.EventHandler<DiscoveryResponse>

handleRpcResponse

final void handleRpcResponse(XdsResourceType<?> type,
                             java.lang.String versionInfo,
                             java.util.List<com.google.protobuf.Any> resources,
                             java.lang.String nonce)

handleRpcStreamClosed

private void handleRpcStreamClosed(io.grpc.Status status)

close

private void close(java.lang.Exception error)

cleanUp

private void cleanUp()
