Class VisitorWithResult

java.lang.Object

org.neo4j.cypherdsl.core.ast.VisitorWithResult

All Implemented Interfaces:

Visitor

public abstract class VisitorWithResult
extends Object
implements Visitor

Sometimes it will be necessary - for example in dialects - to change the flow of elements visited. Some vistables will react on Visitor.enterWithResult(Visitable) and change course (not all, and we don't give any guarantees on any behaviour). This class has been introduced for visitors providing such a behaviour so that an implementation doesn't need to deal with an empty Visitor.enter(Visitable) method.

2022.3.0
