Inheritance diagram for DynExpInstr::NIDAQDigitalInTasks::RestartTask:Public Member Functions | |
| RestartTask (CallbackType CallbackFunc) noexcept | |
| Public Member Functions inherited from DynExp::TaskBase | |
| TaskBase (CallbackType CallbackFunc=nullptr) noexcept | |
| Constructs an instrument task. More... | |
| virtual | ~TaskBase ()=0 |
The destructor aborts a waiting task setting State to TaskState::Aborted. Then, it calls CallbackFunc with a default-constructed ExceptionContainer instance. More... | |
| TaskState | GetState () const noexcept |
| Getter for the instrument task's current state. More... | |
| bool | IsLocked () const noexcept |
| Determines whether the task is locked. More... | |
| bool | IsAborting () const noexcept |
| Determines whether the task should abort. A derived task is encouraged to call this method before performing any action or in between the individual steps of a more complex action. More... | |
| int | GetErrorCode () const noexcept |
| Getter for the error code related to an error possibly occurred while the task was executed. More... | |
| void | Abort () |
Requests the task to abort. There is no guarantee that the derived task does call IsAborting() to check whether it should abort. The task could have finished already or the implementation of RunChild() in the derived class does not allow for aborting. More... | |
Private Member Functions | |
| virtual DynExp::TaskResultType | RunChild (DynExp::InstrumentInstance &Instance) override |
Runs the task. Override RunChild() to define a derived task's action(s). Any exception leaving RunChild() will terminate the instrument thread. In this case, the instrument has to be reset in order to restart it. For minor errors occurring in RunChild(), return a TaskResultType instance with TaskResultType::ErrorCode set to an appropriate (non-zero) value. This sets State to TaskState::Failed. Note that in this case there might be no way to retrieve the error if finished tasks are not kept (i.e. KeepFinishedTask() returns false) and if no CallbackFunc has been set. RunChild() is supposed to check the return value of IsAborting(). More... | |
Additional Inherited Members | |
| Public Types inherited from DynExp::TaskBase | |
| enum class | TaskState { Waiting , Locked , Running , Finished , Failed , Aborted } |
| Defines states an instrument's task can undergo. Possible state transitions are: More... | |
| using | CallbackType = std::function< void(const TaskBase &, ExceptionContainer &)> |
| Type of a callback function which is invoked when a task has finished, failed or has been aborted. The function receives a reference to the task it originates from as well as a reference to a wrapper holding an exception which might have occurred while executing the task. More... | |
| Public Attributes inherited from DynExp::TaskBase | |
| InstrumentBaseOnlyType | InstrumentBaseOnly |
Allow exclusive access to some of TaskBase's private methods to InstrumentBase. More... | |
| InstrumentDataBaseOnlyType | InstrumentDataBaseOnly |
Allow exclusive access to some of TaskBase's private methods to InstrumentDataBase. More... | |
