Direct Known Subclasses:

ReassemblingHandshakeMessage

public class GenericHandshakeMessage
extends HandshakeMessage

Generic handshake message. Use to partially process handshake messages, if they are received out of order an the full processing requires the HandshakeParameter. Offers later creation of specific handshake messages, if the handshake parameters are available.

Constructor Detail

GenericHandshakeMessage

protected GenericHandshakeMessage(HandshakeType type,
                       InetSocketAddress peerAddress)

Create generic handshake message.

Parameters:

type - handshake type

peerAddress - address of peer

Method Detail

getMessageType

public HandshakeType getMessageType()

Description copied from class: HandshakeMessage

Returns the type of the handshake message. See HandshakeType.

Specified by:

getMessageType in class HandshakeMessage

Returns:

the HandshakeType.

getMessageLength

public int getMessageLength()

Description copied from class: HandshakeMessage

Must be implemented by each subclass. The length is given in bytes and only includes the length of the subclass' specific fields (not the handshake message header).

Specified by:

getMessageLength in class HandshakeMessage

Returns:

the length of the message in bytes.

fragmentToByteArray

public byte[] fragmentToByteArray()

Description copied from class: HandshakeMessage

The serialization of the handshake body (without the handshake header). Must be implemented by each subclass. Except the ClientHello, the fragments are considered to be not modified. If a modification is required, call HandshakeMessage.fragmentChanged().

Specified by:

fragmentToByteArray in class HandshakeMessage

Returns:

the raw byte representation of the handshake body.

fromByteArray

public static GenericHandshakeMessage fromByteArray(HandshakeType type,
                                    InetSocketAddress peerAddress)

Read generic generic handshake message from bytes.

Parameters:

type - handshake type

peerAddress - address of peer

Returns:

generic handshake message
