Class QInstanceValidator

java.lang.Object

com.kingsrook.qqq.backend.core.instances.QInstanceValidator

public class QInstanceValidator
extends Object

Class that knows how to take a look at the data in a QInstance, and report if it is all valid - e.g., non-null things are set; references line-up (e.g., a table's backend must be a defined backend). Prior to doing validation, the the QInstanceEnricher is ran over the QInstance, e.g., to fill in things that can be defaulted or assumed. TODO let the instance customize or opt-out of Enrichment.
