Examples of org.hibernate.bytecode.spi.ClassTransformer

org.hibernate.bytecode.spi.ClassTransformer
A persistence provider provides an instance of this interface to the PersistenceUnitInfo.addTransformer method. The supplied transformer instance will get called to transform entity class files when they are loaded and redefined. The transformation occurs before the class is defined by the JVM @author Bill Burke @author Emmanuel Bernard

   * @throws Exception Indicates an issue either access files or applying the transformations.
