ReturnCode_t RTC::PeriodicExecutionContext::activate_component ( LightweightRTObject_ptr  comp) throw (CORBA::SystemException) [virtual]

Activate an RT-component.

Activate an RT-Component.

The given participant RTC is Inactive and is therefore not being invoked according to the execution context°«s execution kind. This operation shall cause the RTC to transition to the Active state such that it may subsequently be invoked in this execution context. The callback on_activate shall be called as a result of calling this operation. This operation shall not return until the callback has returned, and shall result in an error if the callback does.

Parameters:
compThe target RT-Component for activation
Returns:
The return code of ReturnCode_t type

ReturnCode_t RTC::PeriodicExecutionContext::add_component ( LightweightRTObject_ptr  comp) throw (CORBA::SystemException) [virtual]

Add an RT-component.

Add an RT-Component.

The operation causes the given RTC to begin participating in the execution context. The newly added RTC will receive a call to LightweightRTComponent::attach_context and then enter the Inactive state. BAD_PARAMETER will be invoked, if the given RT-Component is null or if the given RT-Component is other than DataFlowComponent.

Parameters:
compThe target RT-Component for add
Returns:
The return code of ReturnCode_t type

Definition at line 526 of file PeriodicExecutionContext.cpp.

int RTC::PeriodicExecutionContext::close ( unsigned long  flags) [virtual]

Thread execution function for ExecutionContext.

This function is invoked when activity thread for ExecutionContext exits. Deactivate the component object and notify it to manager. This is coil::Task class method's override.

Parameters:
flagsFlag of the close
Returns:
The close result

Reimplemented from coil::Task.

Definition at line 190 of file PeriodicExecutionContext.cpp.

ReturnCode_t RTC::PeriodicExecutionContext::deactivate_component ( LightweightRTObject_ptr  comp) throw (CORBA::SystemException) [virtual]

Deactivate an RT-component.

Deactivate an RT-Component.

The given RTC is Active in the execution context. Cause it to transition to the Inactive state such that it will not be subsequently invoked from the context unless and until it is activated again. The callback on_deactivate shall be called as a result of calling this operation. This operation shall not return until the callback has returned, and shall result in an error if the callback does.

Parameters:
compThe target RT-Component for deactivate
Returns:
The return code of ReturnCode_t type

Definition at line 368 of file PeriodicExecutionContext.cpp.

LifeCycleState RTC::PeriodicExecutionContext::get_component_state ( LightweightRTObject_ptr  comp) throw (CORBA::SystemException) [virtual]

Get RT-component's state.

Get RT-Component's state.

This operation shall report the LifeCycleState of the given participant RTC. UNKNOWN_STATE will be returned, if the given RT-Component is not inclued in the participant list.

Parameters:
compThe target RT-Component to get the state
Returns:
The current state of the target RT-Component(LifeCycleState)

Definition at line 478 of file PeriodicExecutionContext.cpp.

ExecutionKind RTC::PeriodicExecutionContext::get_kind ( void  ) throw (CORBA::SystemException) [virtual]

Returns:
The return code of ReturnCode_t type

Definition at line 255 of file PeriodicExecutionContext.cpp.
