Public Methods

 TCPSession (const InetHostAddress &host, tpport_t port, int size=512, int pri=0, int stack=0)
 Create a TCP socket that will be connected to a remote TCP server and that will execute under it's own thread.

 TCPSession (TCPSocket &server, int size=512, int pri=0, int stack=0)
 Create a TCP socket from a bound TCP server by accepting a pending connection from that server and execute a thread for the accepted connection.


Protected Methods

int waitConnection (timeout_t timeout=TIMEOUT_INF)
 Normally called during the thread Initial() method by default, this will wait for the socket connection to complete when connecting to a remote socket.

void initial (void)
 The initial method is used to esablish a connection when delayed completion is used.

void final (void)
 TCPSession derived objects can be freely created with "new" and safely terminate their "run" method on their own by self-deleting when the thread terminates.


Detailed Description

The TCP session is used to primarily to represent a client connection that can be managed on a seperate thread. Threaded streamable socket with non-blocking constructor.

The TCP session also supports a non-blocking connection scheme which prevents blocking during the constructor and moving the process of completing a connection into the thread that executes for the session.

Constructor & Destructor Documentation

ost::TCPSession::TCPSession const InetHostAddress   host,
tpport_t    port,
int    size = 512,
int    pri = 0,
int    stack = 0
 

Create a TCP socket that will be connected to a remote TCP server and that will execute under it's own thread.

Parameters:
host  internet address of remote TCP server.
port  number of remote server.
size  of streaming buffer.
pri  execution priority relative to parent.
stack  allocation needed on some platforms.

ost::TCPSession::TCPSession TCPSocket   server,
int    size = 512,
int    pri = 0,
int    stack = 0
 

Create a TCP socket from a bound TCP server by accepting a pending connection from that server and execute a thread for the accepted connection.

Parameters:
server  tcp socket to accept a connection from.
size  of streaming buffer.
pri  execution priority relative to parent.
stack  allocation needed on some platforms.


Member Function Documentation

void ost::TCPSession::final void    [inline, protected, virtual]
 

TCPSession derived objects can be freely created with "new" and safely terminate their "run" method on their own by self-deleting when the thread terminates.

Reimplemented from ost::Thread.

void ost::TCPSession::initial void    [protected, virtual]
 

The initial method is used to esablish a connection when delayed completion is used.

This assures the constructor terminates without having to wait for a connection request to complete.

Reimplemented from ost::Thread.

int ost::TCPSession::waitConnection timeout_t    timeout = TIMEOUT_INF [protected]
 

Normally called during the thread Initial() method by default, this will wait for the socket connection to complete when connecting to a remote socket.

One might wish to use setCompletion() to change the socket back to blocking I/O calls after the connection completes. To implement the session one must create a derived class which implements run().

Returns:
0 if successful, -1 if timed out.
Parameters:
timeout  to wait for completion in milliseconds.
