Field Detail

delegate

protected final P extends BasicProverEnvironment<T> delegate

solverAssumptionsAsFormula

protected final List<BooleanFormula> solverAssumptionsAsFormula

Method Detail

clearAssumptions

protected void clearAssumptions()

pop

public void pop()

Description copied from interface: BasicProverEnvironment

Remove one formula from the environment stack.

Specified by:

pop in interface BasicProverEnvironment<T>

addConstraint

public T addConstraint(BooleanFormula constraint)

Description copied from interface: BasicProverEnvironment

Add constraint to the context.

Specified by:

addConstraint in interface BasicProverEnvironment<T>

push

public void push()

Description copied from interface: BasicProverEnvironment

Create backtracking point.

Specified by:

push in interface BasicProverEnvironment<T>

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<T>

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. A model might contain additional symbols with their evaluation, if a solver uses its own temporary symbols. There should be at least an value-assignment for each free symbol.

Specified by:

getModel in interface BasicProverEnvironment<T>

Throws:

SolverException

getModelAssignments

public ImmutableList<Model.ValueAssignment> getModelAssignments()
                                                         throws SolverException

Description copied from interface: BasicProverEnvironment

Get a list of satisfying assignments. This is equivalent to ImmutableList.copyOf(getModel()), but removes the need for calling Model.close().

Note that if you need to iterate multiple times over the model it may be more efficient to use this method instead of BasicProverEnvironment.getModel() (depending on the solver).

Specified by:

getModelAssignments in interface BasicProverEnvironment<T>

Throws:

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<T>
