Member Function Documentation

const ACE_INET_Addr& TAO_IIOP_Acceptor::address ( void  ) const

@ Helper method for the implementation repository, should go away

int TAO_IIOP_Acceptor::close ( void  )

Closes the acceptor.

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::create_new_profile ( const TAO::ObjectKey object_key,
TAO_MProfile mprofile,
CORBA::Short  priority 

Helper method to add a new profile to the mprofile for each endpoint.

int TAO_IIOP_Acceptor::create_profile ( const TAO::ObjectKey object_key,
TAO_MProfile mprofile,
CORBA::Short  priority 

Create the corresponding profile for this endpoint. If share_profile is set to true, the pluggable protocol implementation should try to add the endpoint to a profile in the mprofile that is of the same type. Currently, this is used when RT CORBA is enabled.

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::create_shared_profile ( const TAO::ObjectKey object_key,
TAO_MProfile mprofile,
CORBA::Short  priority 

Helper method to create a profile that contains all of our endpoints.

const ACE_INET_Addr& TAO_IIOP_Acceptor::default_address ( void  ) const

Returns address for default endpoint.

int TAO_IIOP_Acceptor::dotted_decimal_address ( const ACE_INET_Addr addr,
char *&  host 

Set the host name for the given address using the dotted decimal format.

CORBA::ULong TAO_IIOP_Acceptor::endpoint_count ( void  )

Returns the number of endpoints this acceptor is listening on. This is used for determining how many profiles will be generated for this acceptor.

Implements TAO_Acceptor.

const ACE_INET_Addr* TAO_IIOP_Acceptor::endpoints ( void  )

Returns the array of endpoints in this acceptor.

int TAO_IIOP_Acceptor::hostname ( TAO_ORB_Core orb_core,
const ACE_INET_Addr addr,
char *&  host,
const char *  specified_hostname = 0 

Set the host name for the given addr. A hostname may be forced by using specified_hostname. This is useful if the given address corresponds to more than one hostname and the desired one cannot be determined in any other way. This method is used both when constructing IOR endpoints and LPL (listen point lists).

The algorithm used is:

  • If hostname_in_ior_ has been set, it is used "as is";
  • else if use_dotted_decimal_addresses_ is set, the text representaion of the IP is used;
  • else if specified_hostname is given, it used "as is";
  • else a reverse (address to name) lookup is used to obtain the hostname or the IP if no reverse mapping exists.
int TAO_IIOP_Acceptor::is_collocated ( const TAO_Endpoint endpoint)

Return 1 if the endpoint has the same address as the acceptor.

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::object_key ( IOP::TaggedProfile &  profile,
TAO::ObjectKey key 

This method fetches the key from the profile. Protocols that are pluggable can send data that are specific in the profile_data field encapsulated as a octet stream. This method allows those protocols to get the object key from the encapsulation.

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::open ( TAO_ORB_Core orb_core,
ACE_Reactor reactor,
int  version_major,
int  version_minor,
const char *  address,
const char *  options = 0 

The TAO_Acceptor methods, check the documentation in Transport_Acceptor.h for details.

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::open_default ( TAO_ORB_Core ,
ACE_Reactor reactor,
int  version_major,
int  version_minor,
const char *  options = 0 

Open an acceptor with the given protocol version on a default endpoint

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::open_i ( const ACE_INET_Addr addr,
ACE_Reactor reactor 

Implement the common part of the open*() methods. This method is virtual to allow a derived class implementation to be invoked instead.

void TAO_IIOP_Acceptor::operator= ( const TAO_IIOP_Acceptor )
int TAO_IIOP_Acceptor::parse_address ( const char *  address,
ACE_INET_Addr addr,
ACE_CString specified_hostname,
int *  def_type = 0 

Helper method Clear out 'addr' & 'specified_hostname' and initialize them based upon 'address'. If a non-zero pointer is passed in for def_type, this will be set to AF_INET6 if IPv6 support is enabled and supplied hostname is either [] or [::]. It will be set to AF_INET if the hostname is, otherwise it is set to AF_UNSPEC. This value is then passed to probe_interfaces by open.

int TAO_IIOP_Acceptor::parse_options ( const char *  options)

Parse protocol specific options.

Currently supported: portspan – specifies the range of ports over which the acceptor should scan looking for a free port (this is convenient for situations where you might normally use an ephemeral port but can't because you're behind a firewall and don't want to permit passage on all ephemeral ports)

int TAO_IIOP_Acceptor::parse_options_i ( int &  argc,
ACE_CString **  argv 

Parse options splits the options list in to an argv array. This allows manipulation of the list in a manner similar to orb_init. By moving the consumed args to the tail of the list and reducing the argc count, the base parse_options_i can be called by derived parse_options_i. Method returns -1 if an ill-formed or otherwise bogus arg is encountered. The only strictly bogus arg was priority, which was a holdover from the early RT IIOP implementations. an ill-formed option is one which is missing an equal sign or something to the left of it.

int TAO_IIOP_Acceptor::probe_interfaces ( TAO_ORB_Core orb_core,
int  def_type = AF_UNSPEC 

Probe the system for available network interfaces, and initialize the <addrs_> array with an ACE_INET_Addr for each network interface. The port for each initialized ACE_INET_Addr will be set in the open_i() method. This method only gets invoked when no explicit hostname is provided in the specified endpoint.

The optional argument def_type is used to constrain the resulting list of interfaces to be either only IPv6 or IPv4, or both, when ACE_HAS_IPV6 is enabled and the source endpoint was an explicitly declared wildcard.

void TAO_IIOP_Acceptor::set_default_address ( const ACE_INET_Addr addr)

Set address for default endpoint.

The number of host names cached in the hosts_ array (equivalent to the number of endpoints opened by this Acceptor).

char* TAO_IIOP_Acceptor::hostname_in_ior_

char** TAO_IIOP_Acceptor::hosts_

Cache the information about the endpoints serviced by this acceptor. There may in fact be multiple hostnames for this endpoint. For example, if the IP address is INADDR_ANY ( then there will be possibly a different hostname for each interface.

TAO_GIOP_Message_Version TAO_IIOP_Acceptor::version_
