All Known Implementing Classes:

SimpleProtocolEncoderOutput
```
public interface ProtocolEncoderOutput
```
Callback for ProtocolEncoder to generate encoded ByteBuffers. ProtocolEncoder must call write(ByteBuffer) for each encoded message.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`WriteFuture`	`flush()`	Flushes all buffers you wrote via `write(ByteBuffer)` to the session.
`void`	`mergeAll()`	Merges all buffers you wrote via `write(ByteBuffer)` into one `ByteBuffer` and replaces the old fragmented ones with it.
`void`	`write(ByteBuffer buf)`	Callback for `ProtocolEncoder` to generate encoded `ByteBuffer`s.

- Method Detail
  - write
```
void write(ByteBuffer buf)
```
    Callback for ProtocolEncoder to generate encoded ByteBuffers. ProtocolEncoder must call write(ByteBuffer) for each encoded message.
    
    Parameters:
    
    buf - the buffer which contains encoded data
  - mergeAll
```
void mergeAll()
```
    Merges all buffers you wrote via write(ByteBuffer) into one ByteBuffer and replaces the old fragmented ones with it. This method is useful when you want to control the way MINA generates network packets.
  - flush
```
WriteFuture flush()
```
    Flushes all buffers you wrote via write(ByteBuffer) to the session. This operation is asynchronous; please wait for the returned WriteFuture if you want to wait for the buffers flushed.
    
    Returns:
    
    null if there is nothing to flush at all.
