              org.antlr.runtime.FailedPredicateException

All Implemented Interfaces:

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 hoist a predicate into a prediction decision.
