|
* A buffered GRXWriter.

|
|
* GRPC only allows a single message to be written to a channel at a time. While the channel is
|
|
* sending, GRPC sets the state of the GRXWriter representing the request stream to
|
|
* GRXWriterStatePaused. Once the channel is ready to accept more messages GRPC sets the state of
|
|
* the writer to GRXWriterStateStarted.

* This class is NOT thread safe, even though it is accessed from multiple threads. To conform with
|
|
* the contract GRPC uses, all method calls on the FSTBufferedWriter must be @synchronized on the
