TAO: TAO_Endpoint Class Reference

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).

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.

Referenced by TAO_Base_Transport_Property::duplicate().

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

Return a hash value for this object.

Implemented in TAO_IIOP_Endpoint.

Referenced by TAO_Base_Transport_Property::hash().

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.

Referenced by TAO_Acceptor_Registry::is_collocated(), next_filtered(), and TAO_IIOP_Profile::~TAO_IIOP_Profile().

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.

TAO_SYNCH_MUTEX TAO_Endpoint::addr_lookup_lock_ [mutable, protected]

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.
