Class SimpleStreamResumptionStrategy<RequestT,ResponseT> (2.46.1)

Simplest implementation of a StreamResumptionStrategy which returns the initial request for unstarted streams.

If a resume request can be created.

Creates a new instance of this StreamResumptionStrategy without accumulated state

Called when a stream needs to be restarted, the implementation should generate a request that will yield a new stream whose first response would come right after the last response received by processResponse.

Called by the ServerStreamingAttemptCallable when a response has been successfully received. This method accomplishes two goals:

1. It allows the strategy implementation to update its internal state so that it can compose the resume request
2. It allows the strategy to alter the incoming responses to adjust for after resume. For example, if the responses are numbered sequentially from the start of the stream, upon resume, the strategy could rewrite the messages to continue the sequence from where it left off. Please note that all messages (even for the first attempt) will be passed through this method.
