All Known Implementing Classes:

SessionOutputBufferImpl
```
public interface SessionOutputBuffer
```
Session output buffer for non-blocking HTTP/1.1 connections.
This interface facilitates intermediate buffering of output data streamed out to a destination channel and provides provides methods for writing lines of text.

Since:

4.0

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`capacity()`	Returns available space in the buffer.
`int`	`flush(java.nio.channels.WritableByteChannel channel)`	Makes an attempt to flush the content of this buffer to the given destination `WritableByteChannel`.
`boolean`	`hasData()`	Determines if the buffer contains data.
`int`	`length()`	Returns the length of this buffer.
`void`	`write(java.nio.ByteBuffer src)`	Copies content of the source buffer into this buffer.
`void`	`write(java.nio.channels.ReadableByteChannel src)`	Reads a sequence of bytes from the source channel into this buffer.
`void`	`writeLine(CharArrayBuffer src)`	Copies content of the source buffer into this buffer as one line of text including a line delimiter.

- Method Detail
  - hasData
```
boolean hasData()
```
    Determines if the buffer contains data.
    
    Returns:
    
    true if there is data in the buffer, false otherwise.
  - capacity
```
int capacity()
```
    Returns available space in the buffer.
    
    Returns:
    
    available space.
  - length
```
int length()
```
    Returns the length of this buffer.
    
    Returns:
    
    buffer length.
  - flush
```
int flush(java.nio.channels.WritableByteChannel channel)
   throws java.io.IOException
```
    Makes an attempt to flush the content of this buffer to the given destination WritableByteChannel.
    
    Parameters:
    
    channel - the destination channel.
    
    Returns:
    
    The number of bytes written, possibly zero.
    
    Throws:
    
    java.io.IOException - in case of an I/O error.
  - write
```
void write(java.nio.ByteBuffer src)
```
    Copies content of the source buffer into this buffer. The capacity of the destination will be expanded in order to accommodate the entire content of the source buffer.
    
    Parameters:
    
    src - the source buffer.
  - write
```
void write(java.nio.channels.ReadableByteChannel src)
    throws java.io.IOException
```
    Reads a sequence of bytes from the source channel into this buffer.
    
    Parameters:
    
    src - the source channel.
    
    Throws:
    
    java.io.IOException
  - writeLine
```
void writeLine(CharArrayBuffer src)
        throws java.nio.charset.CharacterCodingException
```
    Copies content of the source buffer into this buffer as one line of text including a line delimiter. The capacity of the destination will be expanded in order to accommodate the entire content of the source buffer.
    The choice of a char encoding and line delimiter sequence is up to the specific implementations of this interface.
    
    Parameters:
    
    src - the source buffer.
    
    Throws:
    
    java.nio.charset.CharacterCodingException
