- Method Detail
  - stop
```
boolean stop(StateT abstractState,
             java.util.Collection<StateT> reachedAbstractStates,
             Precision precision)
```
    The operator may decide based on the (generalized under the given precision) convergence. In this case it needs to look up the abstractState in the reachedAbstractStates. Otherwise, it can return true if sufficient information is collected, e.g., a safety property is violated.
