java.lang.RuntimeException

org.antlr.v4.runtime.RecognitionException

org.antlr.v4.runtime.FailedPredicateException

All Implemented Interfaces:

java.io.Serializable

public class FailedPredicateException
extends RecognitionException

A semantic predicate failed during validation. Validation of predicates occurs when normally parsing the alternative just like matching a token. Disambiguating predicate evaluation occurs when we test a predicate during prediction.
