ClientStream (gax 2.19.5 API)

Type Parameters:

RequestT - The type of each request.

All Known Implementing Classes:

BidiStream
```
public interface ClientStream<RequestT>
```
A wrapper used to send requests to the server.
After sending requests, users must either call closeSend() or closeSendWithError(Throwable) on the stream. The error, if any, will be propagated to the server.
Example usage:
```
 ClientStream<String> stream = ...;
 List<String> lines = getLinesFromFile();
 for (String line : lines) {
   stream.send(line);
 }
 stream.closeSend();
 
```

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`closeSend()`	Closes the stream.
`void`	`closeSendWithError(java.lang.Throwable t)`	Closes the stream with an error.

- Method Detail
  - send
```
void send(RequestT request)
```
    Sends a request to the server. It is an error to call this if the stream is already closed.
  - closeSendWithError
```
void closeSendWithError(java.lang.Throwable t)
```
    Closes the stream with an error. If called, this must be the last call on this ClientStream.
  - closeSend
```
void closeSend()
```
    Closes the stream. If called, this must be the last call on this ClientStream.
    Note that if close() itself throws, a further call to closeSendWithError is not allowed.
  - isSendReady
```
boolean isSendReady()
```
    Reports whether a new request can be sent without excessive buffering.
    This is only an optimization hint to the user. It is correct, if suboptimal, to call send if isSendReady returns false.
