Method Detail

query

public Boolean query(AbaTheory<T> beliefbase,
                     Assumption<T> query)

Specified by:

query in interface net.sf.tweety.commons.QualitativeReasoner<AbaTheory<T extends net.sf.tweety.commons.Formula>,Assumption<T extends net.sf.tweety.commons.Formula>>

Specified by:

query in interface net.sf.tweety.commons.Reasoner<Boolean,AbaTheory<T extends net.sf.tweety.commons.Formula>,Assumption<T extends net.sf.tweety.commons.Formula>>

query

public Boolean query(AbaTheory<T> beliefbase,
                     Assumption<T> query,
                     net.sf.tweety.commons.InferenceMode inferenceMode)

Queries the given ABA theory for the given assumption using the given inference type.

Parameters:

beliefbase - an ABA theory

query - some assumption

inferenceMode - either InferenceMode.SKEPTICAL or InferenceMode.CREDULOUS

Returns:

"true" if the query is accepted
