◆ computeTruth()

bool klee::DummySolverImpl::computeTruth ( const Query &  query,
bool &  isValid 
)
virtual

computeTruth - Determine whether the given query expression is provably true given the constraints.

The query expression is guaranteed to be non-constant and have bool type.

This method should evaluate the logical formula:

\[ \forall X constraints(X) \to query(X) \]

Where $X$ is some assignment, $constraints(X)$ are the constraints in the query and $query(X)$ is the query expression.

Parameters
[out]isValid- On success, true iff the logical formula is true.
Returns
True on success

Implements klee::SolverImpl.

Definition at line 38 of file DummySolver.cpp.

References klee::stats::queries.

◆ computeValidity()

bool klee::DummySolverImpl::computeValidity ( const Query &  query,
Solver::Validity &  result 
)
virtual

computeValidity - Compute a full validity result for the query.

The query expression is guaranteed to be non-constant and have bool type.

SolverImpl provides a default implementation which uses computeTruth. Clients should override this if a more efficient implementation is available.

Parameters
[out]result- if

\[ \forall X constraints(X) \to query(X) \]

then Solver::True, else if

\[ \forall X constraints(X) \to \lnot query(X) \]

then Solver::False, else Solver::Unknown
Returns
True on success

◆ computeValue()

bool klee::DummySolverImpl::computeValue ( const Query &  query,
ref< Expr > &  result 
)
virtual

computeValue - Compute a feasible value for the expression.

The query expression is guaranteed to be non-constant.

Returns
True on success
