Protected Attributes | |

Private Types | |
| typedef TAO_ESF_Proxy_Collection< PROXY > | Collection |
| Shorthand for the Proxy collection. | |
Private Attributes | |
| Collection * | collection_ |
| The proxy collection object. | |
The EVENT_CHANNEL interface must implement:
* /// create a new proxy * void create_proxy (PROXY*&); * * /// destroy a proxy * void destroy_proxy (PROXY*); * * /// create a proxy collection * void create_proxy_collection (TAO_ESF_Proxy_Collection<PROXY>*&); * * /// destroy a proxy collection * void destroy_proxy_collection (TAO_ESF_Proxy_Collection<PROXY>*&); *
In addition to the requirements imposed by TAO_ESF_Proxy_Collection<>, the PROXY interface must define:
* /// The T_ptr for the IDL interface implemented by the PROXY. * typename .... _ptr_type; * * /// The T_var for the IDL interface implemented by the PROXY. * typename .... _var_type; * * /// activate the proxy and return the object reference * PROXY::_ptr_type * PROXY::activate (void) throw (); *
