Public Methods

void update (unsigned char flag=0xff)
 Notify service thread that a port has been added or removed, or a timer changed, so that a new schedule can be computed for expiring attached ports.

 SocketService (int pri=0)
 Create a service thread for attaching socket ports.

virtual ~SocketService ()
 Terminate the thread pool and eliminate any attached socket ports.

int getCount (void) const
 Get current reference count.


Protected Methods

virtual void onUpdate (unsigned char buf)
 Handles all requests other than "termination".

virtual void onEvent (void)
 Called once each time the service thread is rescheduled.

virtual void onCallback (SocketPort *port)
 Called for each port that is being processed in response to an event.

class SocketPort

Detailed Description

The SocketService is a thread pool object that is meant to service attached socket ports. Thread pool service object for socket ports.

Multiple pool objects may be created and multiple socket ports may be attached to the same thread of execution. This allows one to balance threads and sockets they service rather than either using a single thread for all connections or a seperate thread for each connection. Features can be added through supported virtual methods.

Constructor & Destructor Documentation

ost::SocketService::SocketService int    pri = 0
 

Create a service thread for attaching socket ports.

The thread begins execution with the first attached socket.

Parameters:
pri  of this thread to run under.

virtual ost::SocketService::~SocketService   [virtual]
 

Terminate the thread pool and eliminate any attached socket ports.


Member Function Documentation

int ost::SocketService::getCount void    const [inline]
 

Get current reference count.

This can be used when selecting the least used service handler from a pool.

Returns:
count of active ports.

virtual void ost::SocketService::onCallback SocketPort   port [inline, protected, virtual]
 

Called for each port that is being processed in response to an event.

This can be used to add additional notification options during callback in combination with update().

Parameters:
port  SocketPort who's callback events are being evaluated.

virtual void ost::SocketService::onEvent void    [inline, protected, virtual]
 

Called once each time the service thread is rescheduled.

This is called after the mutex is locked and can be used to slip in additional processing.

virtual void ost::SocketService::onUpdate unsigned char    buf [inline, protected, virtual]
 

Handles all requests other than "termination".

Parameters:
buf  request id as posted from update().

void ost::SocketService::update unsigned char    flag = 0xff
 

Notify service thread that a port has been added or removed, or a timer changed, so that a new schedule can be computed for expiring attached ports.

A "0" is used to terminate the service thread, and additional values can be specified which will be "caught" in the onUpdate() handler.

Parameters:
flag  update flag value.
