All Known Implementing Classes:

```
public interface GridNioParser
```
This interface declares a basic contract on message parsing and encoding to the underlying network layer.
Note that methods of this interface are called within NIO threads and should be as fast as possible. If any of methods throw an exception, corresponding session will be closed and listener will be notified with exception passed in as argument.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`@Nullable Object`	`decode(GridNioSession ses, ByteBuffer buf)`	This method is called when input bytes are available on the underlying network connection.
`ByteBuffer`	`encode(GridNioSession ses, Object msg)`	This method is called whenever a message should be sent to the network connection and network buffer is ready to be filled with bytes.

@Nullable
@Nullable Object decode(GridNioSession ses,
                        ByteBuffer buf)
                 throws IOException,
                        IgniteCheckedException
```
    This method is called when input bytes are available on the underlying network connection.
    Method must read given buffer until either it reaches the end of buffer or a valid user message is encountered. In this case it must return parsed message.
    
    Parameters:
    
    ses - Session on which bytes are read.
    
    buf - Buffer that contains input data.
    
    Returns:
    
    Parsed user message or null if complete message has not been received yet. Note that in case of returning null given buffer must be completely read.
    
    Throws:
    
    IOException - If exception occurred while reading data.
    
    IgniteCheckedException - If any user-specific error occurred.
  - encode
```
ByteBuffer encode(GridNioSession ses,
                  Object msg)
           throws IOException,
                  IgniteCheckedException
```
    This method is called whenever a message should be sent to the network connection and network buffer is ready to be filled with bytes.
    Method must encode the complete message and return byte buffer from which data should be read.
    
    Parameters:
    
    ses - Session on which message is being sent.
    
    msg - Message to encode.
    
    Returns:
    
    Buffer containing encoded message.
    
    Throws:
    
    IOException - If exception occurred while encoding data.
    
    IgniteCheckedException - If any user-specific error occurred while encoding data.
