BufferTransformer (de.enflexit.jade 4.6.4 API)

All Known Implementing Classes:

NIOHTTPHelper, SSLEngineHelper
```
public interface BufferTransformer
```
A buffertransformer is responsible for the preparation of data read from a socket or data to be written to a socket. Implementers are responsible for preparing (ByteBuffer.flip()) the data returned.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`ByteBuffer`	`postprocessBufferRead(ByteBuffer socketData)`	implementers can transform data available read from the socket.
`ByteBuffer`	`preprocessBufferToWrite(ByteBuffer dataToSend)`	implementers can transform the bytes before they are sent.

- Method Detail
  - postprocessBufferRead
```
ByteBuffer postprocessBufferRead(ByteBuffer socketData)
                          throws IOException
```
    implementers can transform data available read from the socket. Any data left in the socketData argument will be used in subsequent NIOJICPConnection.readPacket() calls.
    
    Parameters:
    
    socketData -
    
    Returns:
    
    a buffer containing the transformed data
    
    Throws:
    
    IOException - will be handled by the BEManagementService and if applicable NIOMediator
  - preprocessBufferToWrite
```
ByteBuffer preprocessBufferToWrite(ByteBuffer dataToSend)
                            throws IOException
```
    implementers can transform the bytes before they are sent. When data in the dataToSend argument are left a IOException will be thrown by NIOJICPConnection.writePacket(jade.imtp.leap.JICP.JICPPacket).
    
    Parameters:
    
    dataToSend -
    
    Returns:
    
    the ByteBuffer to send
    
    Throws:
    
    IOException - will be handled by the BEManagementService and if applicable NIOMediator
