Class LoadQueryInfluencers

java.lang.Object

org.hibernate.engine.spi.LoadQueryInfluencers

All Implemented Interfaces:

Serializable

public class LoadQueryInfluencers
extends Object
implements Serializable

Centralize all options which can influence the SQL query needed to load an entity. Currently, such influencers are defined as:

• filters
• fetch profiles
• internal fetch profile (merge profile, etc)

See Also:

• Serialized Form
