Class SActionQuerySatisfactionTester

java.lang.Object

net.sf.tweety.action.query.SActionQuerySatisfactionTester

All Implemented Interfaces:

ActionQuerySatisfactionTester

public class SActionQuerySatisfactionTester
extends Object
implements ActionQuerySatisfactionTester

This class provides methods capable of checking if a given transition system satisfies a set of action queries in the action query language s. This is acomplished by a translation of action queries to normal logic programms presented in [1]. [1] Bachelor thesis. Action und Change: Update von Aktionsbeschreibungen by Sebastian Homann.

SActionQuerySatisfactionTester

public SActionQuerySatisfactionTester(net.sf.tweety.lp.asp.solver.AspInterface aspsolver)

Creates a new instance of this satisfaction tester using the given answer set solver.

Parameters:

aspsolver -

Method Detail

isSatisfied

public boolean isSatisfied(TransitionSystem transitionSystem,
                           net.sf.tweety.commons.BeliefBase actionQueries)

Description copied from interface: ActionQuerySatisfactionTester

Checks whether the given transition system satisfies the given action queries.

Specified by:

isSatisfied in interface ActionQuerySatisfactionTester

Parameters:

transitionSystem - the transition system, that will be checked for satisfaction.

actionQueries - a belief base containing action queries, all of which have to be satisfied by the transition system.

Returns:

true iff the transition system satisfies all action queries in the given belief base.

isSatisfied

public boolean isSatisfied(TransitionSystem transitionSystem,
                           Set<ActionQuery> actionQueries)

Description copied from interface: ActionQuerySatisfactionTester

Checks whether the given transition system satisfies the given action queries.

Specified by:

isSatisfied in interface ActionQuerySatisfactionTester

Parameters:

transitionSystem - the transition system, that will be checked for satisfaction.

actionQueries - a set of action queries, which have to be satisfied by the transition system.

Returns:

true iff the transition system satisfies all action queries in the given set.

regainIllegalCharacters

public String regainIllegalCharacters(String s)

This function exists mainly for debug reasons to regain a human readable version of the atoms in a logic program or in a resulting stable model.

Parameters:

s -
