Class AbstractValidator.JPQLQueryBNFValidator

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

All Implemented Interfaces:

ExpressionVisitor

Enclosing class:

AbstractValidator

public static class AbstractValidator.JPQLQueryBNFValidator
extends AnonymousExpressionVisitor

This visitor validates any Expression by checking its BNF against some BNFs.

Field Summary

protected boolean	bypassCompound
protected boolean	valid Determines whether the visited Expression's BNF is valid based on the BNF that was used for validation.

Constructor Summary

AbstractValidator.JPQLQueryBNFValidator(JPQLQueryBNF queryBNF)
Creates a new JPQLQueryBNFValidator.

Method Summary

void	dispose() Disposes of the internal data.
boolean	isValid() Determines whether the visited Expression is valid or not based on the JPQLQueryBNF that was specified.
void	setBypassCompound(boolean bypassCompound) Sets
void	validate(JPQLQueryBNF queryBNF) Validates the given JPQLQueryBNF by making sure it is the one expected or one of the children from the "root" BNF passed to this validator's constructor.
void	visit(BadExpression expression) Visits the BadExpression expression.
void	visit(CollectionExpression expression) Visits the CollectionExpression expression.
protected void	visit(Expression expression) Blindly visit the given Expression.
void	visit(NullExpression expression) Visits the NullExpression expression.
void	visit(SubExpression expression) Visits the SubExpression expression.
void	visit(UnknownExpression expression) Visits the UnknownExpression expression.
