| TAO_Stub (const TAO_Stub &) | |
| TAO_Stub & | operator= (const TAO_Stub &) |
Per-objref data includes the (protocol-specific) Profile, which is handled by placing it into a subclass of this type along with data that may be used in protocol-specific caching schemes. The type ID (the data specified by CORBA 2.0 that gets exposed "on the wire", and in stringified objrefs) is held by this module. The stub APIs are member functions of this type.

TAO_Abstract_ServantBase* TAO_Stub::collocated_servant_ [protected] |
Servant pointer. It is 0 except for collocated objects.
const CORBA::Boolean TAO_Stub::collocation_opt_ [protected] |
This should be the same value as cached in the ORB_Core. The reason for caching this helps our generated code, notably the stubs to be decoubled from ORB_Core. Please do not move it away.
TAO_MProfile* TAO_Stub::forward_profiles_ [protected] |
The list of forwarding profiles. This is actually implemented as a linked list of TAO_MProfile objects.
TAO_MProfile* TAO_Stub::forward_profiles_perm_ [protected] |
IOP::IOR* TAO_Stub::forwarded_ior_info_ [protected] |
Forwarded IOR info.
IOP::IOR* TAO_Stub::ior_info_ [protected] |
The ior info. This is needed for GIOP 1.2, as the clients could receive an exception from the server asking for this info. The exception that the client receives is LOC_NEEDS_ADDRESSING_MODE. The data is set up here to be passed on to Invocation classes when they receive an exception. This info is for the base profiles that this class stores
CORBA::Boolean TAO_Stub::is_collocated_ [protected] |
Flag that indicates that this stub is collocated (and that it belongs to an ORB for which collocation optimisation is active).
TAO::Object_Proxy_Broker* TAO_Stub::object_proxy_broker_ [protected] |
Pointer to the Proxy Broker.
This cached pointer instance takes care of routing the call for standard calls in CORBA::Object like _is_a (), _get_component () etc.
CORBA::ORB_var TAO_Stub::orb_ [protected] |
TAO_ORB_Core_Auto_Ptr TAO_Stub::orb_core_ [protected] |
Automatically manage the ORB_Core reference count.
The ORB_Core cannot go away until the object references it creates are destroyed. There are multiple reasons for this, but in particular, the allocators used for some of the TAO_Profile objects contained on each TAO_Stub are owned by the TAO_ORB_Core.
This must be the first field of the class, otherwise the TAO_ORB_Core is destroyed too early!
TAO_Policy_Set* TAO_Stub::policies_ [protected] |
The policy overrides in this object, if nil then use the default policies.
TAO_Profile* TAO_Stub::profile_in_use_ [protected] |
This is the profile that we are currently sending/receiving with.

All objref representations carry around a type ID.
