StreamByteDistributor.StreamState (Netty API Reference (5.0.0.Alpha4))

Enclosing interface:

StreamByteDistributor
```
public static interface StreamByteDistributor.StreamState
```
State information for the stream, indicating the number of bytes that are currently streamable. This is provided to the StreamByteDistributor.updateStreamableBytes(StreamState) method.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`hasFrame()`	Indicates whether or not there are frames pending for this stream.
`long`	`pendingBytes()`	Get the amount of bytes this stream has pending to send.
`Http2Stream`	`stream()`	Gets the stream this state is associated with.
`int`	`windowSize()`	The size (in bytes) of the stream's flow control window.

- Method Detail
  - stream
```
Http2Stream stream()
```
    Gets the stream this state is associated with.
  - pendingBytes
```
long pendingBytes()
```
    Get the amount of bytes this stream has pending to send. The actual amount written must not exceed windowSize()!
    
    Returns:
    
    The amount of bytes this stream has pending to send.

  - hasFrame
```
boolean hasFrame()
```
    Indicates whether or not there are frames pending for this stream.
  - windowSize
```
int windowSize()
```
    The size (in bytes) of the stream's flow control window. The amount written must not exceed this amount!
    A StreamByteDistributor needs to know the stream's window size in order to avoid allocating bytes if the window size is negative. The window size being 0 may also be significant to determine when if an stream has been given a chance to write an empty frame, and also enables optimizations like not writing empty frames in some situations (don't write headers until data can also be written).
    
    Returns:
    
    the size of the stream's flow control window.
