- Method Detail
  - headers
```
MultiMap headers()
```
    Returns:
    
    the MultiMap to read metadata headers
  - encoding
```
String encoding()
```
    Returns:
    
    the stream encoding, e.g identity or gzip
  - messageHandler
```
GrpcReadStream<T> messageHandler(Handler<GrpcMessage> handler)
```
    Set a handler to be notified with incoming encoded messages. The handler is responsible for fully decoding incoming messages, including compression.
    
    Parameters:
    
    handler - the message handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - invalidMessageHandler
```
GrpcReadStream<T> invalidMessageHandler(Handler<InvalidMessageException> handler)
```
    Set a message handler that is reported with invalid message errors.
    Warning: setting this handler overwrite the default handler which takes appropriate measure when an invalid message is encountered such as cancelling the stream. This handler should be set when control over invalid messages is required.
    
    Parameters:
    
    handler - the invalid message handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - errorHandler
```
GrpcReadStream<T> errorHandler(Handler<GrpcError> handler)
```
    Set a handler to be notified with gRPC errors.
    
    Parameters:
    
    handler - the error handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - exceptionHandler
```
GrpcReadStream<T> exceptionHandler(Handler<Throwable> handler)
```
    Description copied from interface: ReadStream
    
    Set an exception handler on the read stream.
    
    Specified by:
    
    exceptionHandler in interface ReadStream<T>
    
    Specified by:
    
    exceptionHandler in interface StreamBase
    
    Parameters:
    
    handler - the exception handler
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - handler
```
GrpcReadStream<T> handler(Handler<T> handler)
```
    Description copied from interface: ReadStream
    
    Set a data handler. As data is read, the handler will be called with the data.
    
    Specified by:
    
    handler in interface ReadStream<T>
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - pause
```
GrpcReadStream<T> pause()
```
    Description copied from interface: ReadStream
    
    Pause the ReadStream, it sets the buffer in fetch mode and clears the actual demand.
    While it's paused, no data will be sent to the data handler.
    
    Specified by:
    
    pause in interface ReadStream<T>
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - resume
```
GrpcReadStream<T> resume()
```
    Description copied from interface: ReadStream
    
    Resume reading, and sets the buffer in flowing mode.
    If the ReadStream has been paused, reading will recommence on it.
    
    Specified by:
    
    resume in interface ReadStream<T>
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - fetch
```
GrpcReadStream<T> fetch(long l)
```
    Description copied from interface: ReadStream
    
    Fetch the specified amount of elements. If the ReadStream has been paused, reading will recommence with the specified amount of items, otherwise the specified amount will be added to the current stream demand.
    
    Specified by:
    
    fetch in interface ReadStream<T>
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - endHandler
```
GrpcReadStream<T> endHandler(Handler<Void> handler)
```
    Description copied from interface: ReadStream
    
    Set an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called.
    
    Specified by:
    
    endHandler in interface ReadStream<T>
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - last
```
Future<T> last()
```
    Returns:
    
    the last element of the stream
  - end
```
Future<Void> end()
```
    Returns:
    
    a future signaling when the response has been fully received successfully or failed
  - collecting
```
@Deprecated
default <R,A> Future<R> collecting(java.util.stream.Collector<T,A,R> collector)
```
    Deprecated. instead use ReadStream.collect(Collector)
    
    Returns:
    
    the result of applying a collector on the stream
