Interface SolverContext

All Superinterfaces:

AutoCloseable

All Known Implementing Classes:

AbstractSolverContext, LoggingSolverContext, Mathsat5SolverContext, PrincessSolverContext, SmtInterpolSolverContext

public interface SolverContext
extends AutoCloseable

Instances of this interface provide access to an SMT solver. A single SolverContext should be used only from a single thread.

If you wish to use multiple contexts (even for the same solver), create one SolverContext per each. Formulas can be transferred between different contexts using FormulaManager.translateFrom(BooleanFormula, FormulaManager).

OptimizationProverEnvironment	newOptimizationProverEnvironment(SolverContext.ProverOptions... options) Create a fresh new OptimizationProverEnvironment which encapsulates an assertion stack and allows to solve optimization queries.
ProverEnvironment	newProverEnvironment(SolverContext.ProverOptions... options) Create a fresh new ProverEnvironment which encapsulates an assertion stack and can be used to check formulas for unsatisfiability.
InterpolatingProverEnvironment<?>	newProverEnvironmentWithInterpolation(SolverContext.ProverOptions... options) Create a fresh new InterpolatingProverEnvironment which encapsulates an assertion stack and allows to generate and retrieve interpolants for unsatisfiable formulas.

Method Detail

getFormulaManager

FormulaManager getFormulaManager()

Get the formula manager, which is used for formula manipulation.

newProverEnvironment

ProverEnvironment newProverEnvironment(SolverContext.ProverOptions... options)

Create a fresh new ProverEnvironment which encapsulates an assertion stack and can be used to check formulas for unsatisfiability.

Parameters:

options - Options specified for the prover environment. All of the options specified in SolverContext.ProverOptions are turned off by default.

newProverEnvironmentWithInterpolation

InterpolatingProverEnvironment<?> newProverEnvironmentWithInterpolation(SolverContext.ProverOptions... options)

Create a fresh new InterpolatingProverEnvironment which encapsulates an assertion stack and allows to generate and retrieve interpolants for unsatisfiable formulas. If the SMT solver is able to handle satisfiability tests with assumptions please consider implementing the InterpolatingProverEnvironment interface, and return an Object of this type here.

Parameters:

options - Options specified for the prover environment. All of the options specified in SolverContext.ProverOptions are turned off by default.

newOptimizationProverEnvironment

OptimizationProverEnvironment newOptimizationProverEnvironment(SolverContext.ProverOptions... options)

Create a fresh new OptimizationProverEnvironment which encapsulates an assertion stack and allows to solve optimization queries.

Parameters:

options - Options specified for the prover environment. All of the options specified in SolverContext.ProverOptions are turned off by default.

getVersion

String getVersion()

Get version information out of the solver.

getSolverName

SolverContextFactory.Solvers getSolverName()

Get solver name (MATHSAT5/Z3/etc...).

close

void close()

Close the solver context.

Necessary for the solvers implemented in native code, frees the associated memory.
