Reimplemented in TAO_Default_Resource_Factory.

virtual TAO_Flushing_Strategy* TAO_Resource_Factory::create_flushing_strategy | ( | void |  | ) | `[pure virtual]`

Creates the flushing strategy. The new instance is owned by the caller.

Implemented in TAO_Default_Resource_Factory.

virtual TAO_LF_Strategy* TAO_Resource_Factory::create_lf_strategy | ( | void |  | ) | `[pure virtual]`

Creates the leader followers strategy. The new instance is owned by the caller.

Implemented in TAO_Default_Resource_Factory.

ACE_Lock * TAO_Resource_Factory::create_object_key_table_lock | ( | void |  | ) | `[virtual]`

virtual TAO_Connection_Purging_Strategy* TAO_Resource_Factory::create_purging_strategy | ( | void |  | ) | `[pure virtual]`

Creates the connection purging strategy.

Implemented in TAO_Default_Resource_Factory.

virtual void TAO_Resource_Factory::disable_factory | ( | void |  | ) | `[pure virtual]`

Disables the factory. When a new factory is installed and used, this function should be called on the previously used (default) factory. This should result in proper error reporting if the user attempts to set options on an unused factory.

Implemented in TAO_Default_Resource_Factory.

virtual bool TAO_Resource_Factory::drop_replies_during_shutdown | ( |  | ) | const`[pure virtual]`

Return the value of the strategy that indicates whether the ORB should wait for the replies during shutdown or drop replies during shutdown.

TAO_ProtocolFactorySet * TAO_Resource_Factory::get_protocol_factories | ( | void |  | ) | `[virtual]`

Return an ACE_Reactor to be utilized.

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::init_protocol_factories | ( | void |  | ) | `[virtual]`

This method will loop through the protocol list and using the protocol name field this method will retrieve a pointer to the associated protocol factory from the service configurator. It is assumed that only one thread will call this method at ORB initialization. NON-THREAD-SAFE

Loads the default protocols. This method is used so that the advanced_resource.cpp can call the one in default_resource.cpp without calling unnecessary functions.

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::locked_transport_cache | ( | void |  | ) | `[virtual]`

Should the transport cache have a lock or not? Return 1 if the transport cache needs to be locked else return 0

Reimplemented in TAO_Default_Resource_Factory.
