Class JudgeCriterion

java.lang.Object
dev.langchain4j.test.judge.JudgeCriterion
@Experimental public final class JudgeCriterion extends Object
A criterion for a Judge, written in natural language, for example "mentions the refund amount". Optionally, it defines when it is satisfied and when it is not, which makes the verdicts more consistent and lets the team agree on what the criterion means: 
JudgeCriterion.from("mentions the refund amount")
        .satisfiedWhen("the response states the amount of money that will be refunded")
        .notSatisfiedWhen("the response only says that a refund will be made, without the amount");
A criterion is immutable: satisfiedWhen(String) and notSatisfiedWhen(String) return a new criterion.
