Class IsoSafeEnumeratingDungTheoryGenerator

java.lang.Object

net.sf.tweety.arg.dung.util.IsoSafeEnumeratingDungTheoryGenerator

All Implemented Interfaces:

Iterator<DungTheory>, DungTheoryGenerator, net.sf.tweety.commons.BeliefSetIterator<Argument,DungTheory>

public class IsoSafeEnumeratingDungTheoryGenerator
extends Object
implements DungTheoryGenerator

This generator generators all possible Dung argumentation theories (modulo graph isomorphism). It starts with the argumentation frameworks just consisting of one arguments and then increases their size.

Method Detail

next

public DungTheory next()

Specified by:

next in interface net.sf.tweety.commons.BeliefSetIterator<Argument,DungTheory>

Specified by:

next in interface DungTheoryGenerator

Specified by:

next in interface Iterator<DungTheory>

next

public DungTheory next(Argument arg)

Description copied from interface: DungTheoryGenerator

Generates a new Dung theory where the given argument is enforced to be in the grounded extension

Specified by:

next in interface DungTheoryGenerator

Parameters:

arg - an argument that is enforced to be in the grounded extension of the generated theory.

Returns:

a Dung theory,

setSeed

public void setSeed(long seed)

Description copied from interface: DungTheoryGenerator

Set the seed for the generation. Every two runs of generations with the same seed are ensured to be identical.

Specified by:

setSeed in interface DungTheoryGenerator

Parameters:

seed - some seed.

hasNext

public boolean hasNext()

Specified by:

hasNext in interface net.sf.tweety.commons.BeliefSetIterator<Argument,DungTheory>

Specified by:

hasNext in interface DungTheoryGenerator

Specified by:

hasNext in interface Iterator<DungTheory>
