Package org.hibernate.collection.spi

package org.hibernate.collection.spi

This package defines the SPI of a framework for lazy-initializing and state-tracking collection wrappers.

The interface PersistentCollection and all its implementations belong to an SPI. They are not part of the public API of Hibernate, and are not meant to be used directly by typical programs which use Hibernate for persistence.
