Method Detail

query

public java.lang.Boolean query(AbstractDialecticalFramework beliefbase,
                               Argument formula)

Description copied from interface: Reasoner

Queries the given belief base for the given formula.

Specified by:

query in interface QualitativeReasoner<AbstractDialecticalFramework,Argument>

Specified by:

query in interface Reasoner<java.lang.Boolean,AbstractDialecticalFramework,Argument>

Parameters:

beliefbase - a belief base

formula - a formula

Returns:

the answer to the query

query

public java.lang.Boolean query(AbstractDialecticalFramework beliefbase,
                               Argument formula,
                               InferenceMode inferenceMode)

Queries the given AAF for the given argument using the given inference type.

Parameters:

beliefbase - an AAF

formula - a single argument

inferenceMode - either InferenceMode.SKEPTICAL or InferenceMode.CREDULOUS

Returns:

"true" if the argument is accepted

getModels

public abstract java.util.Collection<Interpretation> getModels(AbstractDialecticalFramework bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Specified by:

getModels in interface ModelProvider<Argument,AbstractDialecticalFramework,Interpretation>

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public abstract Interpretation getModel(AbstractDialecticalFramework 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,AbstractDialecticalFramework,Interpretation>

Parameters:

bbase - some belief base

Returns:

a selected model of the belief base.
