Constructor Details

FileDungTheoryGenerator

public FileDungTheoryGenerator(File[] files,
 Parser<DungTheory,?> parser,
 boolean loop)

Creates a new theory generator for the given files, which can be parsed by the given parser.

Parameters:

files - an array of files.

parser - a parser for the files.

loop - whether to loop the files indefinitely.

Method Details

hasNext

public boolean hasNext()

Specified by:

hasNext in interface BeliefSetIterator<Argument,DungTheory>

Specified by:

hasNext in interface DungTheoryGenerator

Specified by:

hasNext in interface Iterator<DungTheory>

next

public DungTheory next()

Specified by:

next in interface BeliefSetIterator<Argument,DungTheory>

Specified by:

next in interface DungTheoryGenerator

Specified by:

next in interface Iterator<DungTheory>

getAbsolutePathOfNext

public String getAbsolutePathOfNext()

Returns the absolute path of the next file

Returns:

the absolute path of the next file

getPreviousFile

public File getPreviousFile()

Returns the file of the theory previously returned by "next()"

Returns:

the file of the theory previously returned by "next()" (or NULL if there was none)

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.
