Method Detail

decode

@Nullable
public @Nullable GridClientMessage 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.

Specified by:

decode in interface GridNioParser

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

public ByteBuffer encode(GridNioSession ses,
                         Object msg0)
                  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.

Specified by:

encode in interface GridNioParser

Parameters:

ses - Session on which message is being sent.

msg0 - 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.

parseClientMessage

protected GridClientMessage parseClientMessage(GridNioSession ses,
                                               GridTcpRestParser.ParserState state)
                                        throws IOException,
                                               IgniteCheckedException

Parses GridClientMessage from raw bytes.

Parameters:

ses - Session.

state - Parser state.

Returns:

A parsed client message.

Throws:

IOException - On marshaller error.

IgniteCheckedException - If no marshaller was defined for the session.

marshaller

protected GridClientMarshaller marshaller(GridNioSession ses)

Returns marshaller.

Returns:

Marshaller.

toString

public String toString()

Overrides:

toString in class Object
