Method Detail

getFormulaManager

public final 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 final ProverEnvironment newProverEnvironment(SolverContext.ProverOptions... options)

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:

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

newProverEnvironment0

protected abstract ProverEnvironment newProverEnvironment0(Set<SolverContext.ProverOptions> options)

newProverEnvironmentWithInterpolation

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

Description copied from interface: SolverContext

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.

Specified by:

newProverEnvironmentWithInterpolation in interface SolverContext

Parameters:

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

newProverEnvironmentWithInterpolation0

protected abstract InterpolatingProverEnvironment<?> newProverEnvironmentWithInterpolation0(Set<SolverContext.ProverOptions> pSet)

newOptimizationProverEnvironment

public final OptimizationProverEnvironment newOptimizationProverEnvironment(SolverContext.ProverOptions... options)

Description copied from interface: SolverContext

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

Specified by:

newOptimizationProverEnvironment in interface SolverContext

Parameters:

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

newOptimizationProverEnvironment0

protected abstract OptimizationProverEnvironment newOptimizationProverEnvironment0(Set<SolverContext.ProverOptions> pSet)

supportsAssumptionSolving

protected abstract boolean supportsAssumptionSolving()

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.
