## Constructor & Destructor Documentation

TAO_BEGIN_VERSIONED_NAMESPACE_DECL TAO_IIOP_Acceptor::TAO_IIOP_Acceptor | ( | CORBA::Boolean | flag = `0` | ) |

Constructor.

TAO_IIOP_Acceptor::~TAO_IIOP_Acceptor | ( | void |  | ) |

Destructor.

## Member Function Documentation

TAO_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE 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 |  | ) | `[virtual]`

Closes the acceptor.

Implements TAO_Acceptor.

int TAO_IIOP_Acceptor::create_new_profile | ( | const TAO::ObjectKey & | object_key,
|  | TAO_MProfile & | mprofile,
|  | CORBA::Short | priority |
| ) |  |  | `[protected]`

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 |
| ) |  |  | `[virtual]`

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 |
| ) |  |  | `[protected]`

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

ACE_INLINE const ACE_INET_Addr & TAO_IIOP_Acceptor::default_address | ( | void |  | ) | const

Returns address for default endpoint.

int TAO_IIOP_Acceptor::dotted_decimal_address | ( | ACE_INET_Addr & | addr,
|  | char *& | host |
| ) |  |  | `[protected]`

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

CORBA::ULong TAO_IIOP_Acceptor::endpoint_count | ( | void |  | ) | `[virtual]`

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.

ACE_INLINE 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,
|  | ACE_INET_Addr & | addr,
|  | char *& | host,
|  | const char * | specified_hostname = `0` |
| ) |  |  | `[virtual]`

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 | ) | `[virtual]`

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 |
| ) |  |  | `[virtual]`

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` |
| ) |  |  | `[virtual]`

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 * | orb_core,
|  | ACE_Reactor * | reactor,
|  | int | version_major,
|  | int | version_minor,
|  | const char * | options = `0` |
| ) |  |  | `[virtual]`

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 |
| ) |  |  | `[protected, virtual]`

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

int TAO_IIOP_Acceptor::parse_options | ( | const char * | options | ) | `[protected]`

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 |
| ) |  |  | `[protected, virtual]`

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 | ) | `[protected]`

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.

ACE_INLINE void TAO_IIOP_Acceptor::set_default_address | ( | const ACE_INET_Addr & | addr | ) |

Set address for default endpoint.

Override the hostname used in the ORBEndPoint.

char** TAO_IIOP_Acceptor::hosts_`[protected]`

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 (0.0.0.0) then there will be possibly a different hostname for each interface.

unsigned short TAO_IIOP_Acceptor::port_span_`[protected]`

The number of ports over which the acceptor should search (starting at the port specified in each element of addrs_) for an available port. This is specified via the "portspan=" option to the endpoint.

Enable socket option SO_REUSEADDR to be set.

TAO_GIOP_Message_Version TAO_IIOP_Acceptor::version_`[protected]`

The GIOP version for this endpoint @ Theoretically they shouldn't be here!! We need to look at a way to move this out
