Class EclipseLinkContentAssistVisitor

java.lang.Object
  org.eclipse.persistence.jpa.jpql.parser.AnonymousExpressionVisitor
      org.eclipse.persistence.jpa.jpql.AbstractContentAssistVisitor
          org.eclipse.persistence.jpa.jpql.EclipseLinkContentAssistVisitor

All Implemented Interfaces:

EclipseLinkExpressionVisitor, ExpressionVisitor

public class EclipseLinkContentAssistVisitor
extends AbstractContentAssistVisitor
implements EclipseLinkExpressionVisitor

This extension over the default content assist visitor adds the additional support EclipseLink provides.

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.
