boolean	verbose Indicates whether warning messages should be printed to stderr.

Constructor Summary

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

Method Summary

ProtocolGraph	createProtocolGraph(ProtocolGraph[] lower, Context hints) Creates a new ProtocolGraph
SessionIdentifier	createSessionIdentifier(java.util.Properties info, SessionIdentifier[] next) Creates a new session identifier with the provided info.
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.
IpSessionIdentifier	newSessionIdentifier(java.lang.String host, int port) Creates a new TcpIpSessionIdentifier.

Constructor Detail

TcpIpProtocol

public TcpIpProtocol(TcpIpConnectionMgr connection_mgr,
                     Scheduler scheduler,
                     ChunkFactory chunk_factory,
                     MarshallerFactory mf,
                     ContextFactory context_factory)

Constructs a new instance of TcpIpProtocol.

Parameters:

connection_mgr - a connection manager for this protocol;

scheduler - the kernel's scheduler;

chunk_factory - a chunk factory;

mf - a marshaller factory;

context_factory - a context factory

Throws:

JonathanException - if something goes wrong.

Method Detail

setVerbose

public void setVerbose(boolean verbose)

Used to set the verbiage level.

Parameters:

verbose - if true, turn on verbosity

isAnInvocationProtocol

public boolean isAnInvocationProtocol()

Returns false: TcpIpProtocol cannot deal with invocations.

Specified by:

isAnInvocationProtocol in interface Protocol

Returns:

false.

createProtocolGraph

public ProtocolGraph createProtocolGraph(ProtocolGraph[] lower,
                                         Context hints)

Creates a new ProtocolGraph

Specified by:

createProtocolGraph in interface Protocol

Parameters:

lower - lower-level protocol graphs. Ignored as TCP/IP is a leaf.

hints - may contain a "port" key/value pair.

Returns:

a new ProtocolGraph

newSessionIdentifier

public IpSessionIdentifier newSessionIdentifier(java.lang.String host,
                                                int port)

Creates a new TcpIpSessionIdentifier.

Parameters:

host - a port number;

port - an host name;

Returns:

a new TcpIpSessionIdentifier.

createSessionIdentifier

public SessionIdentifier createSessionIdentifier(java.util.Properties info,
                                                 SessionIdentifier[] next)
                                          throws JonathanException

Description copied from interface: Protocol

Creates a new session identifier with the provided info.

Specified by:

createSessionIdentifier in interface Protocol

Parameters:

info - information to create the session identifier.

next - session identifiers of the lower sessions?

Returns:

the created session identifier.

Throws:

JonathanException - if something goes wrong.

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.
