[protected]

Constructor that could be used by the derived classes.

Sometimes new pluggable protocols which have similarities with IIOP may be tempted to this class for their use. Classical example being that of IIOP_SSL_Connection_Handler. This constructor just initializes its base class and sets all of its contents to the default value, if any

Member Function Documentation

int TAO_IIOP_Connection_Handler::open

(

void *

)

[virtual]

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

int TAO_IIOP_Connection_Handler::close

(

u_long

= 0

)

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

int TAO_IIOP_Connection_Handler::resume_handler

(

void

)

[virtual]

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::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

)

[virtual]

int TAO_IIOP_Connection_Handler::handle_close	(	ACE_HANDLE	,
		ACE_Reactor_Mask
	)			[virtual]

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

int TAO_IIOP_Connection_Handler::add_transport_to_cache

(

void

)

Add ourselves to Cache.

int TAO_IIOP_Connection_Handler::process_listen_point_list

(

IIOP::ListenPointList &

listen_list

)

Process the listen_list.

int TAO_IIOP_Connection_Handler::enable_network_priority

(

void

)

Check if network priority needs to be enabled.

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::open_handler

(

void *

)

[virtual]

A open () hook.

See Thread_Per_Connection_Handler for a use case

Implements TAO_Connection_Handler.

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::release_os_resources

(

void

)

[protected, virtual]

Release the OS resources related to this handler.

Reimplemented from TAO_Connection_Handler.

int TAO_IIOP_Connection_Handler::set_tos

(

int

tos

)

[protected]
