Public Member Functions

• SearchEngine (TheoryCore *core)

  Constructor.
  

• virtual ~SearchEngine ()

  Destructor.
  

• virtual const std::string & getName ()=0

  Name of this search engine.
  

• TheoryCore * theoryCore ()

  Accessor for TheoryCore.
  

• virtual void registerAtom (const Expr &e)=0

  Register an atomic formula of interest.
  

• virtual Theorem getImpliedLiteral ()=0

  Return next literal implied by last assertion. Null Expr if none.
  

• virtual Theorem checkValid (const Expr &e)=0

  Checks the validity of a formula in the current context.
  

• virtual Theorem restart (const Expr &e)=0

  Reruns last check with e as an additional assumption.
  

• virtual void returnFromCheck ()=0

  Returns to context immediately before last call to checkValid.
  

• virtual Theorem lastThm ()=0

  Returns the result of the most recent valid theorem.
  

• virtual Theorem newUserAssumption (const Expr &e, int scope=-1)=0

  Generate and add an assumption to the set of assumptions in the current context.
  

• virtual void getUserAssumptions (std::vector< Expr > &assumptions)=0

  Get all user assumptions made in this and all previous contexts.
  

• virtual void getInternalAssumptions (std::vector< Expr > &assumptions)=0

  Get assumptions made internally in this and all previous contexts.
  

• virtual void getAssumptions (std::vector< Expr > &assumptions)=0

  Get all assumptions made in this and all previous contexts.
  

• virtual bool isAssumption (const Expr &e)=0

  Check if the formula has already been assumed previously.
  

• virtual void getCounterExample (std::vector< Expr > &assertions, bool inOrder=true)=0

  Will return the set of assertions which make the queried formula false.
  

• virtual Proof getProof ()=0

  Returns the proof term for the last proven query.
  

• void getConcreteModel (ExprMap< Expr > &m)

  Build a concrete Model (assign values to variables), should only be called after an invalid query.
