Class QQueryRenderer

java.lang.Object

to.etc.webapp.query.QRenderingVisitorBase

to.etc.webapp.query.QQueryRenderer

All Implemented Interfaces:

QNodeVisitor

public class QQueryRenderer
extends QRenderingVisitorBase
implements QNodeVisitor

Render a QCriteria query as something more or less human-readable. This does not extend QNodeVisitorBase anymore because that way we're forced to implement new nodes.
