Detailed Description

template<class T>
class DetectorGraph::SubscriberInterface< T >

A Pure interface that declares the Subscriber behavior.

Detectors inherit from a number of versions of this interface to declare their input set.

A class FooDetector acquires the "Subscriber of BarTopicState" behavior by inheriting SubscriberInterface templated to BarTopicState.

class FooDetector :
    public Detector,
    public SubscriberInterface<BarTopicState>
{
    // ...
}

This interface serves a tiny purpose:

• Abstracts the interface of Subscriber to a Topic into a type-safe method.
• Document in a clear way the Subscriptions of a Detector.

To enable the subscription Detectors must call Detector::Subscribe from the inheriting Detector's constructor:

class FooDetector :
    public Detector,
    public SubscriberInterface<BarTopicState>
{
    FooDetector(Graph* graph) : Detector(graph)
    {
        Subscribe<BarTopicState>(this);
    }
}
