Interface ImplementationCreator

public interface ImplementationCreator

Create instances of PersistenceCapable objects. Instantiation of interfaces or abstract classes is impossible, and for this reason concrete classes are generated and and enhanced at runtime by the ImplementationCreator. The generated classes are loaded/defined by an internal ClassLoader to the ImplementationCreator. The internal ClassLoader delegates to the ClassLoaderResolver (loader) the load of user classes.

Method Summary

java.lang.Object	newInstance(java.lang.Class pc, MetaDataManager mmgr, ClassLoaderResolver loader) Constructs an implementation for an interface and instantiates it
