Class AbstractEclipseLinkTraverseChildrenVisitor

java.lang.Object
  org.eclipse.persistence.jpa.jpql.parser.AnonymousExpressionVisitor
      org.eclipse.persistence.jpa.jpql.parser.AbstractTraverseChildrenVisitor
          org.eclipse.persistence.jpa.jpql.parser.AbstractEclipseLinkTraverseChildrenVisitor

All Implemented Interfaces:

EclipseLinkExpressionVisitor, ExpressionVisitor

public abstract class AbstractEclipseLinkTraverseChildrenVisitor
extends AbstractTraverseChildrenVisitor
implements EclipseLinkExpressionVisitor

This ExpressionVisitor traverses the entire hierarchy of the JPQL parsed tree by going down into each of the children of any given Expression. It is up to the subclass to complete the behavior.

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.
