public AbstractExtensionReasoner()

Method Details

query

public Boolean query(DungTheory beliefbase,
 Argument formula)

Description copied from interface: Reasoner

Queries the given belief base for the given formula.

Specified by:

query in interface QualitativeReasoner<DungTheory,Argument>

Specified by:

query in interface Reasoner<Boolean,DungTheory,Argument>

Specified by:

query in class AbstractDungReasoner

Parameters:

beliefbase - a belief base

formula - a formula

Returns:

the answer to the query

query

public Boolean query(DungTheory 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

getSimpleReasonerForSemantics

public static AbstractExtensionReasoner getSimpleReasonerForSemantics(Semantics semantics)

Creates a reasoner for the given semantics.

Parameters:

semantics - a semantics

Returns:

a reasoner for the given Dung theory, inference type, and semantics

isInstalled

public boolean isInstalled()

the solver is natively installed and is therefore always installed

Specified by:

isInstalled in interface QualitativeReasoner<DungTheory,Argument>

Returns:

if the solver is installed
