Member Function Documentation

◆ abort()

void TAO_IIOP_Connection_Handler::abort ( )

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::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 >.

◆ close_connection()

int TAO_IIOP_Connection_Handler::close_connection ( )

virtual

Add ourselves to Cache.

Implements TAO_Connection_Handler.

◆ enable_network_priority()

int TAO_IIOP_Connection_Handler::enable_network_priority ( )

Check if network priority needs to be enabled.

◆ handle_close()

virtual

Add ourselves to Cache.

Implements TAO_Connection_Handler.

◆ handle_output()

int TAO_IIOP_Connection_Handler::handle_output ( ACE_HANDLE handle )

virtual

Add ourselves to Cache.

Reimplemented from ACE_Event_Handler.

◆ handle_timeout()

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

virtual

Add ourselves to Cache.

Reimplemented from ACE_Svc_Handler< ACE_SOCK_STREAM, ACE_NULL_SYNCH >.

◆ handle_write_ready()

int TAO_IIOP_Connection_Handler::handle_write_ready ( const ACE_Time_Value * timeout )

protectedvirtual

Stores the type of service value.

Reimplemented from TAO_Connection_Handler.

◆ open()

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 >.

◆ open_handler()

int TAO_IIOP_Connection_Handler::open_handler ( void * v )

virtual

Add ourselves to Cache.

Implements TAO_Connection_Handler.

◆ process_listen_point_list()

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 ( )

protectedvirtual

Stores the type of service value.

Reimplemented from TAO_Connection_Handler.

◆ resume_handler()

int TAO_IIOP_Connection_Handler::resume_handler ( )

virtual

◆ set_dscp_codepoint() [1/2]

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.

◆ set_dscp_codepoint() [2/2]

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

virtual

Add ourselves to Cache.

Reimplemented from TAO_Connection_Handler.

◆ set_tos()

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.
