FailedPredicateException (ANTLR 4 Runtime 4.13.1 API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.RuntimeException
    - - org.antlr.v4.runtime.RecognitionException
      - org.antlr.v4.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 test a predicate during prediction.
