Method Details

getFormulaManager

public FormulaManager getFormulaManager()

Description copied from interface: SolverContext

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

Specified by:

getFormulaManager in interface SolverContext

newProverEnvironment

public ProverEnvironment newProverEnvironment(SolverContext.ProverOptions... pOptions)

Description copied from interface: SolverContext

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

Specified by:

newProverEnvironment in interface SolverContext

Parameters:

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

newProverEnvironmentWithInterpolation

public InterpolatingProverEnvironment<?> newProverEnvironmentWithInterpolation(SolverContext.ProverOptions... pOptions)

Description copied from interface: SolverContext

Create a fresh new InterpolatingProverEnvironment which encapsulates an assertion stack and allows generating 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.

Specified by:

newProverEnvironmentWithInterpolation in interface SolverContext

Parameters:

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

newOptimizationProverEnvironment

public OptimizationProverEnvironment newOptimizationProverEnvironment(SolverContext.ProverOptions... pOptions)

Description copied from interface: SolverContext

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

Specified by:

newOptimizationProverEnvironment in interface SolverContext

Parameters:

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

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".

Specified by:

getVersion in interface SolverContext

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

Specified by:

getSolverName in interface SolverContext

getStatistics

public ImmutableMap<String,String> getStatistics()

Description copied from interface: SolverContext

Get statistics for a complete solver context. The returned mapping is intended to provide the solver-internal statistics. The keys can differ between individual solvers.

Calling the statistics several times for the same context returns accumulated number, i.e., we currently do not provide any possibility to reset the statistics.

We do not guarantee any specific key to be present, as this depends on the used solver. We might even return an empty mapping if the solver does not support calling this method or is in an invalid state.

Specified by:

getStatistics in interface SolverContext

• BasicProverEnvironment.getStatistics()

close

public void close()

Description copied from interface: SolverContext

Close the solver context.

After calling this method, further access to any object that had been returned from this context is not wanted, i.e., it depends on the solver. Java-based solvers might wait for the next garbage collection with any cleanup operation. Native solvers might even reference invalid memory and cause segmentation faults.

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

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SolverContext

getSolverStatistics

public SolverStatistics getSolverStatistics()

export statistics about the solver interaction.
