Method Detail

getModels

public java.util.Collection<Extension> getModels(DungTheory bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Specified by:

getModels in interface ModelProvider<Argument,DungTheory,Extension>

Specified by:

getModels in class AbstractExtensionReasoner

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public Extension getModel(DungTheory bbase)

Description copied from interface: ModelProvider

Returns a single (dedicated) model of the given belief base. If the implemented method allows for more than one dedicated model, the selection may be non-deterministic.

Specified by:

getModel in interface ModelProvider<Argument,DungTheory,Extension>

Specified by:

getModel in class AbstractExtensionReasoner

Parameters:

bbase - some belief base

Returns:

a selected model of the belief base.

singleAFExtensions

private java.util.Set<Extension> singleAFExtensions(DungTheory theory)

Computes the extensions for the single af case.

Parameters:

theory - some Dung theory

Returns:

the set of extensions

getOutparents

private java.util.Collection<Argument> getOutparents(DungTheory af,
                                                     java.util.Collection<Argument> s)

Returns the set { a in A | a nicht in S und a -> S }

Parameters:

af - some Dung theory

s - a set of arguments

Returns:

a set of arguments
