All Implemented Interfaces:

Postulate<Argument>
```
public class RaQualityPrecedence
extends RankingPostulate
```
The "quality precedence" postulate for ranking semantics as proposed in [Amgoud, Ben-Naim. Ranking-based semantics for argumentation frameworks. 2013]: The greater the acceptability of one direct attacker for an argument, the weaker the level of acceptability of this argument.

Method Summary

Modifier and Type	Method	Description
`java.lang.String`	`getName()`	The textual name of the postulate
`boolean`	`isApplicable(java.util.Collection<Argument> kb)`	Checks whether the given kb represents a non-trivial instance for this postulate, i.e., whether assumptions of this postulates are satisfied (evaluating an approach on a non-applicable instance always succeeds).
`boolean`	`isSatisfied(java.util.Collection<Argument> kb, AbstractRankingReasoner<ArgumentRanking> ev)`
