Member Function Documentation

ACE_Allocator * TAO_Resource_Factory::amh_response_handler_allocator ( void  ) [virtual]

Access the AMH response handler allocator.

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::ami_response_handler_allocator ( void  ) [virtual]

Access the AMI response handler allocator.

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::cache_maximum ( void  ) const [virtual]

This denotes the maximum number of connections that can be cached.

Reimplemented in TAO_Default_Resource_Factory.

TAO_Codeset_Manager * TAO_Resource_Factory::codeset_manager ( void  ) [virtual]

Gets the codeset manager.

Reimplemented in TAO_Default_Resource_Factory.

ACE_Lock * TAO_Resource_Factory::create_cached_connection_lock ( void  ) [virtual]

Creates the lock for the lock needed in the Cache Map

Deprecated:

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 auto_ptr<TAO_GIOP_Fragmentation_Strategy> TAO_Resource_Factory::create_fragmentation_strategy ( TAO_Transport transport,
CORBA::ULong  max_message_size 
) const [pure virtual]

Outgoing fragment creation strategy.

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.

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.

Implemented in TAO_Default_Resource_Factory.

TAO_Acceptor_Registry * TAO_Resource_Factory::get_acceptor_registry ( void  ) [virtual]

Return a reference to the acceptor registry.

Reimplemented in TAO_Default_Resource_Factory.

TAO_Connector_Registry * TAO_Resource_Factory::get_connector_registry ( void  ) [virtual]

Return a connector to be utilized.

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::get_parser_names ( char **&  names,
int &  number_of_names 
) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

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

The protocol factory list is implemented in this class since a) it will be a global resource and b) it is initialized at start up and then not altered. Returns a container holding the list of loaded protocols.

Reimplemented in TAO_Default_Resource_Factory.

ACE_Reactor * TAO_Resource_Factory::get_reactor ( 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

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::input_cdr_allocator_type_locked ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::input_cdr_buffer_allocator ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::input_cdr_dblock_allocator ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::input_cdr_msgblock_allocator ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::load_default_protocols ( void  ) [protected, virtual]

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.

int TAO_Resource_Factory::max_muxed_connections ( void  ) const [virtual]

Return the number of muxed connections that are allowed for a remote endpoint

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::output_cdr_buffer_allocator ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::output_cdr_dblock_allocator ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

ACE_Allocator * TAO_Resource_Factory::output_cdr_msgblock_allocator ( void  ) [virtual]

Reimplemented in TAO_Default_Resource_Factory.

int TAO_Resource_Factory::purge_percentage ( void  ) const [virtual]

This denotes the amount of entries to remove from the connection cache.

Reimplemented in TAO_Default_Resource_Factory.

void TAO_Resource_Factory::reclaim_reactor ( ACE_Reactor reactor) [virtual]

Reclaim reactor resources (e.g. deallocate, etc).

Reimplemented in TAO_Default_Resource_Factory.

virtual TAO_Resource_Factory::Resource_Usage TAO_Resource_Factory::resource_usage_strategy ( void  ) const [pure virtual]

Return the resource usage strategy.

Implemented in TAO_Default_Resource_Factory.

void TAO_Resource_Factory::use_local_memory_pool ( bool  ) [virtual]
