QueryResult VCL::query | ( | const Expr & | e | ) | [virtual] |

If it returns VALID, the scope and context are the same as when called. If it returns INVALID, the context will be one which falsifies the query. If it returns UNKNOWN, the context will falsify the query, but the context may be inconsistent. Finally, if it returns ABORT, the context will be one which satisfies as much as possible.

bool VCL::incomplete | ( | ) | [virtual] |
Returns true if the invalid result from last query() is imprecise.
Some decision procedures in CVC are incomplete (quantifier elimination, non-linear arithmetic, etc.). If any incomplete features were used during the last query(), and the result is "invalid" (query() returns false), then this result is inconclusive. It means that the system gave up the search for contradiction at some point.
