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.

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

getModelWithoutChecks

protected abstract Model getModelWithoutChecks()
                                        throws SolverException

model computation without checks for further options.

Throws:

SolverException - if model can not be constructed.
