extends RecognitionException

Imports
org.antlr.v4.runtime.atn.ATNState, .AbstractPredicateTransition, .PredicateTransition, java.util.Locale
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.
