Class AbstractValidator.ExpressionValidator

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

All Implemented Interfaces:

ExpressionVisitor

Enclosing class:

AbstractValidator

protected static class AbstractValidator.ExpressionValidator

extends AnonymousExpressionVisitor

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

Field Summary

private JPQLQueryBNF	queryBNF The query BNF used to determine if the expression's BNF is valid.
private JPQLQueryBNF[]	queryBNFs The list of query BNFs used to determine if the expression's BNF is valid.
boolean	valid Determines whether the visited Expression's BNF is valid based on the BNF that was used for validation.

Constructor Summary

protected	AbstractValidator.ExpressionValidator(JPQLQueryBNF... queryBNFs) Creates a new ExpressionValidator.
protected	AbstractValidator.ExpressionValidator(JPQLQueryBNF queryBNF) Creates a new ExpressionValidator.

Method Summary

private void	allJPQLQueryBNFs(java.util.Set<JPQLQueryBNF> queryBNFs, JPQLQueryBNF queryBNF)
private void	validate(JPQLQueryBNF queryBNF)
void	visit(BadExpression expression) Visits the BadExpression 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.
