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

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.

SocketService::~SocketService ( )
 

Terminate the thread pool and eliminate any attached socket ports.


Member Function Documentation

void 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:
SocketPort   who's callback events are being evaluated.

void 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.

void SocketService::OnUpdate ( unsigned char buf ) [inline, protected, virtual]
 

Handles all requests other than "termination".

Parameters:
request   id as posted from Update().

void 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:
Update   flag value.

int 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.
