TAO_Wait_Strategy::TAO_Wait_Strategy | ( | TAO_Transport * | transport | ) | [explicit] |
Constructor.
TAO_Wait_Strategy::~TAO_Wait_Strategy | ( | void | ) | [virtual] |
Destructor.
virtual bool TAO_Wait_Strategy::can_process_upcalls | ( | void | ) | const [pure virtual] |
Flag that indicates whether we can process requests while waiting for the reply. This flag is to check whether the thread can process upcalls while waiting for the reply. Some wait strategies, like Wait_On_LF_No_Upcall does not allow the client threads to process requests while waiting for the reply.
Implemented in TAO_Wait_On_Leader_Follower, TAO_Wait_On_Read, TAO::Wait_On_LF_No_Upcall, and TAO_Wait_On_Reactor.
int TAO_Wait_Strategy::defer_upcall | ( | ACE_Event_Handler * | ) | [virtual] |
Method to support deffering an upcall event till later in cases where can_process_upcalls() returns false. Some wait strategies like Wait_On_LF_No_Upcall allow an event to be deferred at the Leader_Follower which resumes the upcall at an opportune moment (when a new leader thread is activated).
Reimplemented in TAO::Wait_On_LF_No_Upcall.
void TAO_Wait_Strategy::finished_request | ( | ) | [virtual] |
Reimplemented in TAO_Wait_On_Read.
bool TAO_Wait_Strategy::is_registered | ( | void | ) | const |
Get method for the flag.
void TAO_Wait_Strategy::is_registered | ( | bool | flag | ) |
Set method for the flag.
virtual bool TAO_Wait_Strategy::non_blocking | ( | void | ) | const [pure virtual] |
Returns a value to indicate whether the transport needs to set the socket on which it is waiting to non-blocking mode or not.
Implemented in TAO_Wait_On_Leader_Follower, TAO_Wait_On_Read, and TAO_Wait_On_Reactor.
virtual int TAO_Wait_Strategy::register_handler | ( | void | ) | [pure virtual] |
Register the handler needs with the reactor provided that it makes sense for the strategy.
Implemented in TAO_Wait_On_Leader_Follower, TAO_Wait_On_Read, and TAO_Wait_On_Reactor.
int TAO_Wait_Strategy::sending_request | ( | TAO_ORB_Core * | orb_core, |
TAO_Message_Semantics | msg_semantics | ||
) | [virtual] |
The user is going to send a request, prepare any internal variables because the reply may arrive *before* the user calls wait.
Reimplemented in TAO_Wait_On_Leader_Follower, and TAO_Wait_On_Read.
virtual int TAO_Wait_Strategy::wait | ( | ACE_Time_Value * | max_wait_time, |
TAO_Synch_Reply_Dispatcher & | rd | ||
) | [pure virtual] |
Base class virtual method. Wait till the reply_received
flag is true or the time expires.
Implemented in TAO_Wait_On_Leader_Follower, TAO::Wait_On_LF_No_Upcall, TAO_Wait_On_Read, and TAO_Wait_On_Reactor.
bool TAO_Wait_Strategy::is_registered_ [protected] |
Flag to indicate whether the service handler that created the above transport has been registered with the reactor or not. The default is false.
TAO_Transport* TAO_Wait_Strategy::transport_ [protected] |
Transport object.
