All Implemented Interfaces:

PersistentPropertyAccessorFactory

public class ClassGeneratingPropertyAccessorFactory
extends Object
implements PersistentPropertyAccessorFactory

A factory that can generate byte code to speed-up dynamic property access. Uses the PersistentEntity's PersistentProperty to discover the access to properties. Properties are accessed either using method handles to overcome Java visibility issues or directly using field access/getter/setter calls.
