Constructor & Destructor Documentation

ServiceHandler() [1/2]

template<class PEER_STREAM>

ASSA::ServiceHandler< PEER_STREAM >::ServiceHandler ( )

inline

Default constructor.

In case of server-side, ServiceHandler is created by Acceptor, when new connection is detected.

Definition at line 38 of file ServiceHandler.h.

        : m_peerStream (new PEER_STREAM)
        {
            trace("ServiceHandler::ServiceHandler");
        }

References m_peerStream, and trace.

ServiceHandler() [2/2]

template<class PEER_STREAM>

ASSA::ServiceHandler< PEER_STREAM >::ServiceHandler ( PEER_STREAM * ps_ )

inline

Constructor that takes PEER_STREAM as a parameter.

In case of server-side, ServiceHandler is created by Acceptor, when new connection is detected. Note that PEER_STREAM is created by PEER_STREAM::accept () method.

Definition at line 49 of file ServiceHandler.h.

        : m_peerStream (ps_) 
        {
            trace("ServiceHandler::ServiceHandler");
        }

References m_peerStream, and trace.

~ServiceHandler()

template<class PEER_STREAM>

virtual ASSA::ServiceHandler< PEER_STREAM >::~ServiceHandler ( )

inlinevirtual

Destructor closes and deletes PEER_STREAM.

Definition at line 56 of file ServiceHandler.h.

                               {
        trace("ServiceHandler::~ServiceHandler");
 
        if ( m_peerStream ) {
            delete m_peerStream;
            m_peerStream = (PEER_STREAM*) NULL;
        }
    }

Member Function Documentation

close()

template<class PEER_STREAM>

virtual void ASSA::ServiceHandler< PEER_STREAM >::close ( void )

inlinevirtual

Pure virtual method defined by subclass.

The close() hook closes PEER_STREAM by default The behavior of this method can be changed by a subclass, which typically performs any service-specific cleanup. EventHandler::handle_close() method of base class EventHandler is called when client closes connection. ServiceHandler object can destroy itself from there.

Definition at line 81 of file ServiceHandler.h.

        {
            trace("ServiceHandler::close");
            if ( m_peerStream ) m_peerStream->close ();
        }

References m_peerStream, and trace.

get_stream()

template<class PEER_STREAM>

PEER_STREAM & ASSA::ServiceHandler< PEER_STREAM >::get_stream ( )

inline

Return referenct to underlying PEER_STREAM.

Definition at line 100 of file ServiceHandler.h.

{ return *m_peerStream; }

References m_peerStream.

open()

template<class PEER_STREAM>

virtual int ASSA::ServiceHandler< PEER_STREAM >::open ( void )

pure virtual

Pure virtual method defined by subclass.

The open() hook is called by the Acceptor or Connector once a connection is established. The behavior of this method must be defined by a subclass, which typically performs any service-specific initialization.

Implemented in ASSA::RemoteLogger.

operator PEER_STREAM &()

template<class PEER_STREAM>

ASSA::ServiceHandler< PEER_STREAM >::operator PEER_STREAM & ( )

inline

Conversion operator to type PEER_STREAM &.

Comes handy when you want to call underlying PEER_STREAM member functions directly.

Returns

reference to underlying stream mechanism

Definition at line 93 of file ServiceHandler.h.

        { 
            // trace("ServiceHandler::opt PEER_STREAM& ()");
            return *m_peerStream;
        }

Member Data Documentation

m_peerStream
