Member Function Documentation

TAO_Stub * TAO_ServantBase::_create_stub (  ACE_ENV_SINGLE_ARG_DECL    )  [virtual]

This is an auxiliar method for _this() and _narrow(). Implements TAO_Abstract_ServantBase. Reimplemented in TAO_Local_ServantBase.

PortableServer::POA_ptr TAO_ServantBase::_default_POA (  ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS    )  [virtual]

Returns the default POA for this servant. Reimplemented in ServerObject_i.

virtual void TAO_ServantBase::_dispatch (  TAO_ServerRequest &    request, void *servant_upcall    ACE_ENV_ARG_DECL )  [pure virtual]

Dispatches a request to the object: find the operation, cast the type to the most derived type, demarshall all the parameters from the request and finally invokes the operation, storing the results and out parameters (if any) or the exceptions thrown into <request>. Implements TAO_Abstract_ServantBase. Implemented in TAO_Local_ServantBase.

virtual void* TAO_ServantBase::_downcast (  const char *    repository_id )  [pure virtual]

Get the correct vtable. Implements TAO_Abstract_ServantBase. Implemented in POA_ImplementationRepository::ServerObject, POA_ImplementationRepository::Administration, POA_ImplementationRepository::ServerInformationIterator, POA_ImplementationRepository::Locator, and POA_CORBA::Policy.

int TAO_ServantBase::_find (  const char *    opname, TAO_Collocated_Skeleton &    skelfunc, TAO::Collocation_Strategy    st, const unsigned int    length = 0 )  [virtual]

Implements TAO_Abstract_ServantBase.

int TAO_ServantBase::_find (  const char *    opname, TAO_Skeleton &    skelfunc, const unsigned int    length = 0 )  [virtual]

Please see documentation in tao/Abstract_Servant_Base.h for details. Implements TAO_Abstract_ServantBase.

CORBA::Object_ptr TAO_ServantBase::_get_component (  ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS    )  [virtual]

Default <_get_component>: always returns CORBA::Object::_nil(). Implements TAO_Abstract_ServantBase.

CORBA::InterfaceDef_ptr TAO_ServantBase::_get_interface (  ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS    )  [virtual]

Query the Interface Repository for the interface definition. Implements TAO_Abstract_ServantBase.

virtual const char* TAO_ServantBase::_interface_repository_id (  void    )  const [protected, pure virtual]

Get this interface's repository id (TAO specific). Implements TAO_Abstract_ServantBase. Implemented in POA_ImplementationRepository::ServerObject, POA_ImplementationRepository::Administration, POA_ImplementationRepository::ServerInformationIterator, POA_ImplementationRepository::Locator, and POA_CORBA::Policy.
