AbstractValidator

java.lang.Object
- org.eclipse.persistence.jpa.jpql.parser.AnonymousExpressionVisitor
- - org.eclipse.persistence.jpa.jpql.AbstractValidator

All Implemented Interfaces:

ExpressionVisitor

Direct Known Subclasses:

AbstractGrammarValidator, AbstractSemanticValidator
```
public abstract class AbstractValidator
extends AnonymousExpressionVisitor
```
The abstract definition of a validator, which provides helper methods and visitors.
Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Since:

2.4

2.5
