Class FetchProfile

java.lang.Object
org.hibernate.engine.profile.FetchProfile
Direct Known Subclasses:
DefaultFetchProfile
public class FetchProfile extends Object
The runtime representation of a Hibernate fetch profile defined in annotations.

Fetch profiles compete with JPA-defined named entity graphs. The semantics of these two facilities are not identical, however, since a fetch profile is a list, not a graph, and is not by nature rooted at any one particular entity. Instead, given a root entity as input, an active fetch profile contributes to the determination of the fetch graph.

A named fetch profile may be enabled in a given session by calling Session.enableFetchProfile(String).
