| Encapsulates code common to _is_a(), _get_interface() and _create_stub().

## Detailed Description

Base class for DSI.

It is expected that the <invoke> and <_primary_interface> methods will be only invoked by the POA in the context of serving a CORBA request. Invoking this method in other circumstances may lead to unpredictable results.

## Member Function Documentation

TAO_Stub * TAO_DynamicImplementation::_create_stub | ( |  | ) | `[protected, virtual]`

This is an auxiliary method for _this() and _narrow().

void TAO_DynamicImplementation::_dispatch | ( | TAO_ServerRequest & | request,
|  | void * | context |
| ) |  |  | `[protected, virtual]`

Turns around and calls invoke.

void * TAO_DynamicImplementation::_downcast | ( | const char * | repository_id | ) | `[protected, virtual]`

Simply returns "this".

CORBA::InterfaceDef_ptr TAO_DynamicImplementation::_get_interface | ( |  | ) | `[virtual]`

Query the Interface Repository for the interface definition.

const char * TAO_DynamicImplementation::_interface_repository_id | ( | void |  | ) | const`[protected, virtual]`

Return 0. Should never be used.

TAO_BEGIN_VERSIONED_NAMESPACE_DECL CORBA::Boolean TAO_DynamicImplementation::_is_a | ( | const char * | logical_type_id | ) | `[virtual]`

Local implementation of the CORBA::Object::_is_a method.

virtual CORBA::RepositoryId TAO_DynamicImplementation::_primary_interface | ( | const PortableServer::ObjectId & | oid,
|  | PortableServer::POA_ptr | poa |
| ) |  |  | `[pure virtual]`

The _primary_interface() method receives an ObjectId value and a POA_ptr as input parameters and returns a valid RepositoryId representing the most-derived interface for that oid.

CORBA::Object_ptr TAO_DynamicImplementation::_this | ( |  | ) |

Returns a CORBA::Object_ptr for the target object.

CORBA::RepositoryId TAO_DynamicImplementation::get_id_from_primary_interface | ( |  | ) | `[private]`

Encapsulates code common to _is_a(), _get_interface() and _create_stub().

virtual void TAO_DynamicImplementation::invoke | ( | CORBA::ServerRequest_ptr | request | ) | `[pure virtual]`

The invoke() method receives requests issued to any CORBA object incarnated by the DSI servant and performs the processing necessary to execute the request.
