                              com.google.api.core.ApiClock clock)

Constructor for RetryingUnaryRpcListener.

Parameters:

retryOptions - a RetryOptions object.

request - a RequestT object.

retryableRpc - a BigtableAsyncRpc object.

callOptions - a CallOptions object.

executorService - a ScheduledExecutorService object.

metadata - a Metadata object.

clock - a ApiClock object

Method Detail

onMessage

public void onMessage(ResponseT message)

Overrides:

onMessage in class io.grpc.ClientCall.Listener<ResponseT>

onOK

protected boolean onOK(io.grpc.Metadata trailers)

A subclass has the opportunity to perform the final operations it needs now that the RPC is successfully complete. If a subclass has to retry, due to the message, this method will return false

Specified by:

onOK in class AbstractRetryingOperation<RequestT,ResponseT,ResponseT>

Returns:

true if the operation was really completed.
