Constructor Detail

LoggingProverEnvironment

public LoggingProverEnvironment(LogManager logger,
                        ProverEnvironment pe)

Method Detail

push

public Void push(BooleanFormula f)

Description copied from interface: BasicProverEnvironment

Push a backtracking point and add a formula to the environment stack, asserting it. The return value may be used to identify this formula later on in a query (this depends on the sub-type of the environment).

Specified by:

push in interface BasicProverEnvironment<Void>

pop

public void pop()

Description copied from interface: BasicProverEnvironment

Remove one formula from the environment stack.

Specified by:

pop in interface BasicProverEnvironment<Void>

addConstraint

public Void addConstraint(BooleanFormula constraint)

Description copied from interface: BasicProverEnvironment

Add constraint to the context.

Specified by:

addConstraint in interface BasicProverEnvironment<Void>

push

public void push()

Description copied from interface: BasicProverEnvironment

Create backtracking point.

Specified by:

push in interface BasicProverEnvironment<Void>

isUnsat

public boolean isUnsat()
                throws SolverException,
                       InterruptedException

Description copied from interface: BasicProverEnvironment

Check whether the conjunction of all formulas on the stack is unsatisfiable.

Specified by:

isUnsat in interface BasicProverEnvironment<Void>

Throws:

SolverException

InterruptedException

getModel

public Model getModel()
               throws SolverException

Description copied from interface: BasicProverEnvironment

Get a satisfying assignment. This should be called only immediately after an BasicProverEnvironment.isUnsat() call that returned false.

Specified by:

getModel in interface BasicProverEnvironment<Void>

Throws:

SolverException

getUnsatCore

public List<BooleanFormula> getUnsatCore()

Description copied from interface: ProverEnvironment

Get an unsat core. This should be called only immediately after an BasicProverEnvironment.isUnsat() call that returned false.

Specified by:

getUnsatCore in interface ProverEnvironment

allSat

public <T> T allSat(ProverEnvironment.AllSatCallback<T> callback,
           List<BooleanFormula> important)
         throws InterruptedException,
                SolverException

Description copied from interface: ProverEnvironment

Get all satisfying assignments of the current environment with regards to a subset of terms, and create a region representing all those models.

Specified by:

allSat in interface ProverEnvironment

important - A set of variables appearing in f. Only these variables will appear in the region.

Returns:

A region representing all satisfying models of the formula.

Throws:

InterruptedException

SolverException

close

public void close()

Description copied from interface: BasicProverEnvironment

Closes the prover environment. The object should be discarded, and should not be used after closing.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface BasicProverEnvironment<Void>
