Field Summary

Fields

Modifier and Type	Field and Description
protected Set<IVariable>	alwaysBound The set of variables which are bound in ALL solutions.
protected Map<IVariable,IConstant>	constants The set of variables which are effective constants (they are bound in every solution and always to the same value) together with their constant bindings.
protected Set<IVariable>	materialized The set of variables whose bound values always have their IVCache assertion set (if the variable is bound).
protected Set<IVariable>	notAlwaysBound The set of variables which are NOT bound in at least one solution (e.g., MAYBE bound semantics).
protected long	nsolutions The #of solutions.
protected Set<IVariable>	usedVars The set of variables observed across all solutions.
