Class MetadataDrivenModelGraphVisitor

java.lang.Object

org.hibernate.persister.walking.spi.MetadataDrivenModelGraphVisitor

public class MetadataDrivenModelGraphVisitor
extends Object

Provides model graph visitation based on the defined metadata (as opposed to based on the incoming graph as we see in cascade processing). In layman terms, we are walking the graph of the users model as defined by mapped associations.

Re-implementation of the legacy JoinWalker contract to leverage load plans.
