Class EntityDescriptor

java.lang.Object
  de.schwarzrot.data.access.support.EntityDescriptor

public class EntityDescriptor
extends Object

an description container like Class- or BeanInfo class, that holds meta-information about an entity. As the default java introspection is not usable for this persistence layer, we do the introspection by ourself - mainly to get rid of types used with generics.
