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

)

[protected, virtual]

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

)

[protected, virtual]

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.
