  class Net_API TCPServerDispatcher: public Poco::Runnable

A helper class for TCPServer that dispatches connections to server connection threads. { public: TCPServerDispatcher(TCPServerConnectionFactory* pFactory, Poco::ThreadPool& threadPool, TCPServerParams* pParams); Creates the TCPServerDispatcher. The dispatcher takes ownership of the TCPServerParams object. If no TCPServerParams object is supplied, the TCPServerDispatcher creates one.


          void duplicate();

Increments the object's reference count. void release(); Decrements the object's reference count and deletes the object if the count reaches zero.


          void run();

Runs the dispatcher. void enqueue(const StreamSocket& socket); Queues the given socket connection.


          void stop();

Stops the dispatcher. int currentThreads() const; Returns the number of currently used threads. int totalConnections() const; Returns the total number of handled connections. int currentConnections() const; Returns the number of currently handled connections.


          int maxConcurrentConnections() const;

Returns the maximum number of concurrently handled connections. int queuedConnections() const; Returns the number of queued connections. int refusedConnections() const; Returns the number of refused connections.


          const TCPServerParams& params() const;

Returns a const reference to the TCPServerParam object.


  protected:
          ~TCPServerDispatcher();

Destroys the TCPServerDispatcher.


          void beginConnection();

Updates the performance counters. void endConnection(); Updates the performance counters.
