java.lang.Object

org.sosy_lab.java_smt.basicimpl.AbstractProver<T>

org.sosy_lab.java_smt.basicimpl.AbstractProverWithAllSat<T>

All Implemented Interfaces:

AutoCloseable, BasicProverEnvironment<T>

public abstract class AbstractProverWithAllSat<T>
extends AbstractProver<T>

This class is a utility-class to avoid repeated implementation of the AllSAT computation.

If a solver does not support direct AllSAT computation, please inherit from this class.

SolverException

Description copied from interface: BasicProverEnvironment

Get all satisfying assignments of the current environment with regard to a subset of terms, and create a region representing all those models.

importantPredicates - A set of (positive) variables appearing in the asserted queries. Only these variables will appear in the region.

Returns:

A region representing all satisfying models of the formula.

Throws:

InterruptedException

SolverException

getEvaluatorWithoutChecks

protected abstract Evaluator getEvaluatorWithoutChecks()
                                                throws SolverException

Get an evaluator instance for model evaluation without executing checks for prover options.

This method allows model evaluation without explicitly enabling the prover-option SolverContext.ProverOptions.GENERATE_MODELS. We only use this method internally, when we know about a valid solver state. The returned evaluator does not have caching or any direct optimization for user interaction.

Throws:

SolverException - if model can not be constructed.
