Examples with ProxyFactory org.hibernate.proxy.ProxyFactory used on opensource projects

Example 1 with ProxyFactory

use of org.hibernate.proxy.ProxyFactory in project hibernate-orm by hibernate.

the class PojoEntityTuplizer method buildProxyFactory.

@Override
protected ProxyFactory buildProxyFactory(PersistentClass persistentClass, Getter idGetter, Setter idSetter) {
    // determine the id getter and setter methods from the proxy interface (if any)
    // determine all interfaces needed by the resulting proxy
    /*
		 * We need to preserve the order of the interfaces they were put into the set, since javassist will choose the
		 * first one's class-loader to construct the proxy class with. This is also the reason why HibernateProxy.class
		 * should be the last one in the order (on JBossAS7 its class-loader will be org.hibernate module's class-
		 * loader, which will not see the classes inside deployed apps.  See HHH-3078
