Function details

void sofa::core::DataTrackerEngine::addCallback ( std::function< sofa::core::objectmodel::ComponentState(void)>  f)

set the update function to call when asking for an output and any input changed.

void sofa::core::DataTrackerEngine::update ( )
overridevirtual

Calls the callback when one of the data has changed.

Each callback in the engine is called, setting its owner's component state to the value returned by the last callback. Because each callback overwrites the state of the same component, it is important that within a component, all callbacks perform the same checks to determine the value of the ComponentState.
