RaAdditionOfDefenseBranch()

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)`
