Class AbstractUjoExt<UJO_IMPL extends UjoExt>

java.lang.Object
  org.ujoframework.extensions.AbstractUjo
      org.ujoframework.extensions.AbstractUjoExt<UJO_IMPL>

All Implemented Interfaces:

UjoCloneable, UjoExt<UJO_IMPL>, UjoMiddle<UJO_IMPL>, UjoTextable, Ujo

Direct Known Subclasses:

ArrayUjoExt, BeanUjoExt, FieldUjoExt, MapUjoExt

public abstract class AbstractUjoExt<UJO_IMPL extends UjoExt>
extends AbstractUjo
implements UjoExt<UJO_IMPL>

This is a simple abstract implementation of Ujo.
For implementation define only a "public static final UjoProperty" constants in a child class. The code syntax is Java 1.5 complied.

Features: very simple implementaton and a sufficient performance for common tasks. The architecture is useful for a rare assignment of values in object too.
