Class AbstractContentAssistVisitor.VisitParentVisitor

java.lang.Object

org.eclipse.persistence.jpa.jpql.parser.AnonymousExpressionVisitor

org.eclipse.persistence.jpa.jpql.tools.AbstractContentAssistVisitor.VisitParentVisitor

All Implemented Interfaces:

ExpressionVisitor

Enclosing class:

AbstractContentAssistVisitor

protected static final class AbstractContentAssistVisitor.VisitParentVisitor
extends AnonymousExpressionVisitor

This visitor is meant to adjust the corrections stack when traversing an Expression in order to increase the list of valid proposals.

For instance, if the query is "SELECT e FROM Employee e WHERE IN" and the cursor is at the end of the query, then IN would be parsed with InExpression. However, due to how AbstractContentAssistVisitor works, the identifier INDEX is not added as a valid proposal. This visitor adds that functionality.
