Class AbstractLazyInitializer

java.lang.Object
  org.hibernate.proxy.AbstractLazyInitializer

All Implemented Interfaces:

LazyInitializer

Direct Known Subclasses:

BasicLazyInitializer, Dom4jLazyInitializer, MapLazyInitializer

public abstract class AbstractLazyInitializer
extends Object
implements LazyInitializer

Convenience base class for lazy initialization handlers. Centralizes the basic plumbing of doing lazy initialization freeing subclasses to acts as essentially adapters to their intended entity mode and/or proxy generation strategy.
