Member Function Documentation

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

This is an auxiliary 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 POA_CORBA::Policy_tie< T >.

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, 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.

virtual 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 [pure virtual]

Get this interface's repository id (TAO specific). Implements TAO_Abstract_ServantBase. Implemented in POA_CORBA::Policy.

CORBA::Boolean TAO_ServantBase::_is_a (  const char *logical_type_id  ACE_ENV_ARG_DECL_WITH_DEFAULTS  )  [virtual]

Local implementation of the CORBA::Object::_is_a method. Implements TAO_Abstract_ServantBase. Reimplemented in POA_CORBA::Policy.

virtual CORBA::Boolean TAO_ServantBase::_non_existent (  ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS   )  [virtual]

Default _non_existent: always returns false. Implements TAO_Abstract_ServantBase.

void TAO_ServantBase::asynchronous_upcall_dispatch (  TAO_ServerRequest &  req, void *  servant_upcall, void *derived_this  ACE_ENV_ARG_DECL )  [protected, virtual]

TAO_ServantBase & TAO_ServantBase::operator= (  const TAO_ServantBase &   )  [protected]

Assignment operator.

void TAO_ServantBase::synchronous_upcall_dispatch (  TAO_ServerRequest &  req, void *  servant_upcall, void *derived_this  ACE_ENV_ARG_DECL )  [protected, virtual]

Implements TAO_Abstract_ServantBase.
