Member Data Documentation

IOP::IOR_var CORBA::Object::ior_ [private]
 

If the IOR hasnt been evaluated fully, then the contents of the IOR that we received should be in here!

CORBA::Boolean CORBA::Object::is_collocated_ [private]
 

Flag to indicate collocation. It is 0 except for collocated objects.

Boolean CORBA::Object::is_evaluated_ [private]
 

Flag to indicate whether the IOP::IOR has been evaluated fully.

CORBA::Boolean CORBA::Object::is_local_ [private]
 

Specify whether this is a local object or not.

TAO_ORB_Core* CORBA::Object::orb_core_ [private]
 

Cached pointer of our ORB_Core.

Reimplemented in TAO_CDR_Encaps_Codec, TAO_CodecFactory, TAO_ORBInitInfo, and TAO::PICurrent.

TAO_Stub* CORBA::Object::protocol_proxy_ [private]
 

Pointer to the protocol-specific "object" containing important profiling information regarding this proxy. The protocol proxy is (potentially) shared among several Objects

TAO::Object_Proxy_Broker* CORBA::Object::proxy_broker_ [private]
 

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.

Number of outstanding references to this object.

Reimplemented in TAO_Local_RefCounted_Object.

ACE_Lock* CORBA::Object::refcount_lock_ [private]

TAO_Abstract_ServantBase* CORBA::Object::servant_ [protected]
 

Servant pointer. It is 0 except for collocated objects.
