Detailed Description

Defines the Endpoint interface in the Pluggable Protocol framework.

Lightweight encapsulation of addressing information for a single acceptor endpoint. In other words, Endpoint represents a single point of contact for the server, and is the smallest unit of addressing information necessary for a client to connect to a server. A Profile contains one or more Endpoints, i.e., knows of one or more ways to contact server(s).


Constructor & Destructor Documentation

TAO_Endpoint::TAO_Endpoint ( CORBA::ULong  tag,
CORBA::Short  priority = TAO_INVALID_PRIORITY 
)

Constructor.

TAO_Endpoint::~TAO_Endpoint ( void   )  [virtual]

Destructor.

TAO_Endpoint::TAO_Endpoint ( const TAO_Endpoint  )  [private]

Endpoints should not be copied.


Member Function Documentation

virtual int TAO_Endpoint::addr_to_string ( char *  buffer,
size_t  length 
) [pure virtual]

Return a string representation for the address.

The purpose of this method is to provide a general interface to the underlying address object's addr_to_string method. This allows the protocol implementor to select the appropriate string format.

Returns:
-1 if buffer is too small.

Implemented in TAO_IIOP_Endpoint.

virtual TAO_Endpoint* TAO_Endpoint::duplicate ( void   )  [pure virtual]

This method returns a deep copy of the corresponding endpoints by allocating memory.

Implemented in TAO_IIOP_Endpoint.

virtual CORBA::ULong TAO_Endpoint::hash ( void   )  [pure virtual]

Return a hash value for this object.

Implemented in TAO_IIOP_Endpoint.

virtual CORBA::Boolean TAO_Endpoint::is_equivalent ( const TAO_Endpoint other_endpoint  )  [pure virtual]

Returns:
true if this endpoint is equivalent to other_endpoint.

Implemented in TAO_IIOP_Endpoint.

virtual TAO_Endpoint* TAO_Endpoint::next ( void   )  [pure virtual]

Endpoints can be linked in a list.

Returns:
The next endpoint in the list, if any.

Implemented in TAO_IIOP_Endpoint.

TAO_Endpoint * TAO_Endpoint::next_filtered ( TAO_ORB_Core ,
TAO_Endpoint root 
) [virtual]

Return the next endpoint in the list, but use protocol-specific filtering to constrain the value. The orb core is needed to supply any sort of filter arguments, and the root endpoint is needed in case the algorithm needs to rewind. If the supplied root is 0, then this is assumed to be the candidate next endpoint.

To use this, the caller starts off the change with root == 0. This is a bit of a violation in logic, a more correct implementation would accept this == 0 and a non-null root. To do iteration using next_filtered, do: for (TAO_Endpoint *ep = root_endpoint->next_filtered (orb_core, 0); ep != 0; ep = ep->next_filtered(orb_core, root_endpoint)) { }

Reimplemented in TAO_IIOP_Endpoint.

void TAO_Endpoint::operator= ( const TAO_Endpoint  )  [private]

Lock for the address lookup.

Todo:
This lock should be strategized so that we dont lock in single threaded configurations. It is not possible to do this now as most of the information is available in the ORB_Core which is not available here.

CORBA::Short TAO_Endpoint::priority ( void   )  const

<priority_> attribute getter.

void TAO_Endpoint::priority ( CORBA::Short  priority  ) 

<priority_> attribute setter.

CORBA::ULong TAO_Endpoint::tag ( void   )  const

IOP protocol tag accessor.


Member Data Documentation

TAO_SYNCH_MUTEX TAO_Endpoint::addr_lookup_lock_ [mutable, protected]

Lock for the address lookup.

Todo:
This lock should be strategized so that we dont lock in single threaded configurations. It is not possible to do this now as most of the information is available in the ORB_Core which is not available here.

Cache the hash value.

CORBA priority of the acceptor this Endpoint is representing. This is part of TAO 'prioritized endpoints' architecture, and is currently used for RTCORBA only.

CORBA::ULong const TAO_Endpoint::tag_ [protected]

IOP tag, identifying the protocol for which this endpoint contains addressing info.
