  +--org.objectweb.jonathan.libs.protocols.tcpip.TcpIpProtocol

All Implemented Interfaces:

Protocol

public final class TcpIpProtocol

extends Object

implements Protocol

This is an implementation of the Protocol interface representing the TCP/IP stack.

Field Summary

boolean

verbose Indicates whether warning messages should be printed to stderr.

Constructor Summary

TcpIpProtocol(Context _c, TcpIpConnectionMgr connection_mgr, Scheduler scheduler, ChunkFactory chunk_factory, MarshallerFactory mf)
Constructs a new instance of TcpIpProtocol.

Method Summary

boolean	isAnInvocationProtocol() Returns false: TcpIpProtocol cannot deal with invocations.
boolean	isLocal(IpSessionIdentifier tcp_session_id) Returns true if the provided session identifier corresponds to a local connection managed by this protocol.
ProtocolGraph	newProtocolGraph() Creates a new ProtocolGraph.
ProtocolGraph	newProtocolGraph(int port) Creates a new ProtocolGraph.
IpSessionIdentifier	newSessionIdentifier(String host, int port) Creates a new TcpIpSessionIdentifier.

Constructor Detail

TcpIpProtocol

public TcpIpProtocol(Context _c,
                     TcpIpConnectionMgr connection_mgr,
                     Scheduler scheduler,
                     ChunkFactory chunk_factory,
                     MarshallerFactory mf)
              throws JonathanException

Constructs a new instance of TcpIpProtocol.

Parameters:

_c - a bootstrap Context instance;

connection_mgr - a connection manager for this protocol;

scheduler - the kernel's scheduler;

chunk_factory - a chunk factory;

mf - a marshaller factory;

Throws:

JonathanException - if something goes wrong.

Method Detail

isAnInvocationProtocol

Specified by:

isAnInvocationProtocol in interface Protocol

Returns:

false.

newProtocolGraph

public final ProtocolGraph newProtocolGraph()

Creates a new ProtocolGraph.

Returns:

a new ProtocolGraph.

newProtocolGraph

public final ProtocolGraph newProtocolGraph(int port)

Creates a new ProtocolGraph.

Parameters:

port - a port number;

Returns:

a new ProtocolGraph.

newSessionIdentifier

public final IpSessionIdentifier newSessionIdentifier(String host,
                                                      int port)

Creates a new TcpIpSessionIdentifier.

Parameters:

host - a port number;

port - an host name;

Returns:

a new TcpIpSessionIdentifier.

isLocal

public boolean isLocal(IpSessionIdentifier tcp_session_id)

Returns true if the provided session identifier corresponds to a local connection managed by this protocol.

Parameters:

tcp_session_id - a TcpIpSessionIdentifier.

Returns:

true if the provided session identifier corresponds to a local connection managed by this protocol, otherwise false.
