TAO_IIOP_Connection_Handler::TAO_IIOP_Connection_Handler ( TAO_ORB_Core * orb_core )

Constructor.

TAO_IIOP_Connection_Handler::~TAO_IIOP_Connection_Handler ( void )

Destructor.

Member Function Documentation

void TAO_IIOP_Connection_Handler::abort ( void )

This is used during a canceled connection attempt. Force the SO_LINGER timeout to 0 so that when the peer is closed, it won't hang around.

int TAO_IIOP_Connection_Handler::add_transport_to_cache ( void )

Add ourselves to Cache.

int TAO_IIOP_Connection_Handler::close ( u_long flags = 0 )

virtual

Close called by the Acceptor or Connector when connection establishment fails.

Reimplemented from ACE_Svc_Handler< ACE_SOCK_STREAM, ACE_NULL_SYNCH >.

int TAO_IIOP_Connection_Handler::close_connection ( void )

virtual

Close the underlying connection.

Used by the ORB to actively close connections that are idle, stale or somehow are determined to be broken before the Reactor does.

Returns: Return 0 if the connection was already closed, non-zero otherwise.

Implements TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::enable_network_priority ( void )

Check if network priority needs to be enabled.

int TAO_IIOP_Connection_Handler::handle_close	(	ACE_HANDLE	,
		ACE_Reactor_Mask
	)

virtual

Reimplemented from ACE_Svc_Handler< ACE_SOCK_STREAM, ACE_NULL_SYNCH >.

int TAO_IIOP_Connection_Handler::handle_input ( ACE_HANDLE fd )

virtual

The event handler calls, here so that other objects who hold a reference to this object can call the event handler methods.

Implements TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::handle_output ( ACE_HANDLE handle )

virtual

Reimplemented from ACE_Event_Handler.

int TAO_IIOP_Connection_Handler::handle_timeout	(	const ACE_Time_Value &	current_time,
		const void *	act = `0`
	)

virtual

Reimplemented from ACE_Svc_Handler< ACE_SOCK_STREAM, ACE_NULL_SYNCH >.

int TAO_IIOP_Connection_Handler::handle_write_ready ( const ACE_Time_Value * timeout )

protectedvirtual

Derived classes should implement this for proper support with the Blocking Flushing Strategy.

Reimplemented from TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::open ( void * )

virtual

Called by the Strategy_Acceptor when the handler is completely connected. Argument is unused.

Reimplemented from ACE_Svc_Handler< ACE_SOCK_STREAM, ACE_NULL_SYNCH >.

int TAO_IIOP_Connection_Handler::open_handler ( void * )

virtual

A open () hook.

See Thread_Per_Connection_Handler for a use case

Implements TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::process_listen_point_list ( IIOP::ListenPointList & listen_list )

Process the listen_list.

int TAO_IIOP_Connection_Handler::release_os_resources ( void )

protectedvirtual

Release the OS resources related to this handler.

Reimplemented from TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::resume_handler ( void )

virtual

Reimplemented from ACE_Event_Handler.

int TAO_IIOP_Connection_Handler::set_dscp_codepoint ( CORBA::Boolean set_network_priority )

virtual

Set Diff-Serv codepoint on outgoing packets.

Reimplemented from TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::set_dscp_codepoint ( CORBA::Long dscp_codepoint )

virtual

Reimplemented from TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::set_tos ( int tos )

protected

helper function used by the set_dscp_codepoint () methods to set the TOS field in the IP packets.
