Class ClassDescriptorImpl

java.lang.Object
  org.exolab.castor.mapping.loader.ClassDescriptorImpl

All Implemented Interfaces:

NatureExtendable, PropertyHolder, ClassDescriptor

public class ClassDescriptorImpl
extends Object
implements ClassDescriptor

The standard ClassDescriptor implementation, holding general OO information about the class described.

Engines will use Natures to augment this class with engine-specific knowledge and functionality, using addNature(String) to register these views with this class.

Once a Nature has been registered with this ClassDescriptor, the nature can be applied to the ClassDescriptor and nature-specific properties can be accessed in a type-safe way.
