public AbstractNode()
```
- Method Detail
  - getPropagator
```
public abstract Propagator getPropagator()
```
    Instead of calling the propagation directly from here, we export the propagation queue and allow BavetConstraintSession to call it. This is done with the idea that Propagator only has two implementations (unlike AbstractNode with myriad implementations) and therefore JVM call site optimizations will kick in to make the method dispatch faster.
    
    Returns:
    
    never null; the PropagationQueue in use by this node
