virtual void setActivity(ActivityInterface *task)
Set the task this interface is run in.
virtual ~RunnableInterface()
Checks if this is still in a task and if so, issues a critical warning.
virtual bool isRunning() const =0
Query if the activity is initialized and executing.
virtual os::ThreadInterface * getThread() const
Get the thread this object is run in.
virtual void step()=0
The method that will be (periodically) executed when this object is run in an Activity.
A thread which is being run.
virtual bool hasWork()
This method is for &#39;intelligent&#39; activity implementations that wish to see if it is required to call ...
Interface to start/stop and query a Activity.
virtual os::ThreadInterface * thread()=0
Returns a pointer to the thread which will run this activity.
Notify the Logger in which &#39;module&#39; the message occured.
Definition: Logger.hpp:159
virtual void loop()
The method that will be executed once when this class is run in a non periodic Activity.
virtual bool breakLoop()
This method is called by the framework to break out of the loop() method.
Contains TaskContext, Activity, OperationCaller, Operation, Property, InputPort, OutputPort, Attribute.
Definition: Activity.cpp:52
RunnableInterface()
Create a runnable object.
void disableRun(RunnableInterface *caller)
This method is only meant for RunnableInterface (ie runner) in order to inform the ActivityInterface ...
virtual void work(WorkReason reason)
Identical to step() but gives a reason why the function was called.
