Method Detail

create

public static SolverContext create(LogManager pLogger,
                                   ShutdownNotifier pShutdownNotifier,
                                   int randomSeed,

                                   FloatingPointRoundingMode pFloatingPointRoundingMode)

getVersion

public String getVersion()

Description copied from interface: SolverContext

Get version information out of the solver.

In most cases, the version contains the name of the solver followed by some numbers and additional info about the version, e.g., "SMTInterpol 2.5-12-g3d15a15c".

close

public void close()

Description copied from interface: SolverContext

Close the solver context.

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

getSolverName

public SolverContextFactory.Solvers getSolverName()

Description copied from interface: SolverContext

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

This is an uppercase String matching the enum identifier from SolverContextFactory.Solvers

newProverEnvironment0

public ProverEnvironment newProverEnvironment0(Set<SolverContext.ProverOptions> pOptions)

Specified by:

newProverEnvironment0 in class AbstractSolverContext

supportsAssumptionSolving

protected boolean supportsAssumptionSolving()

Description copied from class: AbstractSolverContext

Whether the solver supports solving under some given assumptions (with all corresponding features) by itself, i.e., whether BasicProverEnvironment.isUnsatWithAssumptions(java.util.Collection) and BasicProverEnvironment.isUnsatWithAssumptions(java.util.Collection) are fully implemented.

Otherwise, i.e., if this method returns false, the solver does not need to support this feature and may simply throw UnsupportedOperationException in the respective methods. This class will wrap the prover environments and provide an implementation of the feature.

This method is expected to always return the same value. Otherwise the behavior of this class is undefined.
